Important note emergency calls
The iDECT X2 is not designed for making emergency calls if the mains power fails. So you should make alternative arrangements for access to Emergency Services. (This means that you should also have a basic phone, that does not need mains power, connected to your line so that you can make calls during a power failure.)
Unpacking your iDECT X2 system
In the box are: the cordless handset (up to four, depending on which iDECT X2 system youve bought) the base unit two batteries and a battery compartment cover for each handset a telephone line cable for the base unit a mains power lead and adapter for the base unit up to three charger pods, each with a separate mains power lead and adapter, for multi-handset systems Keep the packaging materials in a safe place in case you later need to transport the unit. Keep your sales (till) receipt, which is your guarantee. Before you can use the handset to make calls youll need to fit and fully charge the batteries, as described on pages 5 and 6. Please read the notes on page 4 before you install the base unit.

Connection and conditions for use
You can connect your iDECT X2 to a direct exchange line (DEL) a line connected to a local exchange, with its own phone number; to an extension socket connected to a DEL; or to an extension on an approved compatible PBX. Do not connect the iDECT X2 as an extension to a payphone. The ringer equivalence numbers (RENs) of all instruments (phones, fax machines, etc.) connected to an exchange line must not add up to more than 4 otherwise, one or more of them may not ring and/or answer calls correctly. The iDECT X2 has a REN of 1, and most other telephones have a REN of 1 unless marked otherwise.

Always use the battery pack supplied never use any other kind of batteries in the handset.
Charge the batteries for 15 hours Before you use the handset for the first time, its important to charge the batteries fully. The handset beeps when its correctly in position on the charging cradle. Leave the handset on the charging cradle for 15 hours.
The battery charge level symbol blinks

Before you start

Electrical safety
DONT let the base unit or charger pod get wet. Electrical equipment can cause serious injury if used while you are wet or standing in water. If the base unit or charger pod ever falls into water, DONT retrieve it until you have unplugged the power lead from the mains and the telephone line plug from the telephone socket (base unit only); then pull it out by the unplugged cables. NEVER use your iDECT X2 outdoors during a thunderstorm unplug the base unit from the telephone line and the mains socket when there are storms in your area. Damage caused by lightning is not covered by the guarantee. If the sound quality gets worse as you move around while on a call, this is probably caused by interference between the handset and the base unit, perhaps because you are too near to another phone or other electrical equipment. Move to a different position to clear the interference. If you do not move, your call may be cut off.

Interference

Out of range warning
Radio interference in the environment may occasionally cause a short break in the link between the handset and the base unit while you are on a call. The signal level on symbol handsets display may flash until the link is restored. If you hear a warning tone during a call, and/or the sound in the earpiece becomes faint or distorted, you may be going out of range of the base unit. Move nearer to the base unit within 20 seconds, until the tone stops. Otherwise, your call may be cut off.

When the handset is switched off, it wont ring for incoming calls, but the base unit will ring. To answer a call when the handset is switched off, you need to switch it back on. It may take a few moments for the handset to re-establish a radio link with the base unit.

The phone does not ring

There is interference and noise on the line.
Move the handset closer to the base unit, or to a different position. Try moving the base unit so that its not near other electrical equipment, such as a television or a computer.
Youll get the best results if you site the base unit as high as possible. For example, in a two-storey house, the first-floor landing is an ideal place for the base unit. My call was cut off when I went out of range. Now I cant use my handset. I hear beeps from my handset while Im on a call. Move the handset closer to the base unit before you try again to make a call.
You may be going out of range of the base unit. Move closer, or your call may be cut off. Check the battery charge level symbol on the display. If it is low, recharge the batteries. You need to subscribe to the Caller Display feature. Contact your service provider (BT or cable company). The caller may have withheld their number by dialling 141. Or they may be calling from a network that does not transmit the Caller ID (for example, it may be an international call). If you have more than one handset registered to your base unit, make sure that another handset isnt already using the line.
The Caller Display feature isnt working.
When I try to make a call, I hear Busy tone. The volume in the earpiece is low when Im on a call.
Make sure youre holding the earpiece correctly over your ear. Adjust the volume using the or button.
I cant transfer a call. Make sure the other handset is in range of the base unit. Make sure youre dialling the correct number for the other handset (1 to 4, or for all registered handsets).

Batteries

The handsets batteries are running low within an hour or two. Before you first used the handset, you should have left it on the base unit or charger pod for up to 15 hours to charge the batteries fully. You may need to replace the batteries (see below). Clean the battery charging contacts on the base unit with a dry cloth. Check the connections between the base unit and the mains power socket. I try to recharge the batteries, but I still get a warning that they are low. Dispose of used batteries safely never burn them, or put them where they could get punctured. ALWAYS use the batteries supplied with your iDECT X2 other batteries may burst, causing damage.

PBX use

You may need to change the recall signal length from The Recall function doesnt its default of 100 ms. Consult your PBX documentation for help if necessary. To change the recall setting, use seem to work. the BASE SETTING menu (page 34).
Last Number Redial and/or memory dialling dont work on a PBX.
When you first make a call, after keying in the outside line access code (e.g. 9), press and hold the Last Number Redial button until a P appears on the display. This inserts a pause between the access code and the telephone number. You should later be able to redial the number. When storing numbers in memory, you can include the outside line access code (e.g. 9) with each number. If your PBX requires you to wait for a second Dial tone before dialling the telephone number, press and hold the Last Number Redial button for a pause between the access code and the number.

If the fault persists

Disconnect all other instruments connected to the same line as the iDECT X2 and see whether you can make a call. Disconnect the base unit from the telephone line and plug a different phone into the master telephone socket. Try making a call. If this works, the line is OK. If the call does not work, and you are using a two-way socket adapter, remove it and plug a telephone directly into the socket. If the call now works, the adapter may be faulty. If you cannot make a call, the fault may be on the exchange line. Contact the service provider (the BT engineers on 151, or your cable company).

The signal level on symbol handsets display may flash until the link is restored. If you hear a warning tone during a call, and/or the sound in the earpiece becomes faint or distorted, you may be going out of range of the base unit. Move nearer to the base unit within 20 seconds, until the tone stops. Otherwise, your call may be cut off.

Caller Display

Troubleshooting

ALWAYS check first that:
The iDECT X2 must be serviced by trained engineers. NEVER attempt any repairs or adjustments yourself you could make the problem worse and invalidate the Guarantee.
you have followed all the steps listed on pages 5 to 7 to install and set up your iDECT X2 all connectors are firmly inserted in their sockets mains power is switched on at the socket the handsets batteries are correctly and securely installed, and are not run down

Everyday use

I cannot make If the handsets display is blank, it may be switched off. or answer calls. Press the HANG UP button to switch it back on. Check that the base units mains power adapter is plugged in and power is switched on. The base unit needs mains power for normal operation of the phone not just for charging the batteries. Make sure youre using the telephone line cable that was supplied with your iDECT X2. Other telephone line cables might not work. Move the handset closer to the base unit. Check the Battery Level symbol on the display. If its low, replace the handset on the base unit or charger pod to recharge the batteries. Switch off power at the mains socket, wait for a few seconds and then switch back on. This may help.

I cannot make a call.

The handsets keypad may be locked (see page 9). Unlock it before you make a call. Call barring may be set. Refer to pages to for details.
When I press keys, nothing happens. When I key in a number, it appears on the display, but I cant make an outside call.
Make sure the batteries are correctly fitted in your handset. If the battery charge level symbol on the display shows low, recharge the batteries. Try moving the handset closer to the base unit. Try a different position for the base unit somewhere higher if possible, or further from other electrical equipment. If you have more than one registered handset, make sure another handset isnt already using the line. Check that the base units mains power adapter is plugged in and power is switched on. The base unit needs mains power for normal operation of the phone not just for charging the batteries. Make sure youre using the telephone line cable that was supplied with your iDECT X2. Other telephone line cables might not work. Check that the total REN value of all equipment connected to your telephone line is no more than 4 (see page 3). Disconnect one or more telephones and see whether that helps.

The phone does not ring

There is interference and noise on the line.
Move the handset closer to the base unit, or to a different position. Try moving the base unit so that its not near other electrical equipment, such as a television or a computer.
Youll get the best results if you site the base unit as high as possible. For example, in a two-storey house, the first-floor landing is an ideal place for the base unit. My call was cut off when I went out of range. Now I cant use my handset. I hear beeps from my handset while Im on a call. Move the handset closer to the base unit before you try again to make a call.
You may be going out of range of the base unit. Move closer, or your call may be cut off. Check the battery charge level symbol on the display. If it is low, recharge the batteries. You need to subscribe to the Caller Display feature. Contact your service provider (BT or cable company). The caller may have withheld their number by dialling 141. Or they may be calling from a network that does not transmit the Caller ID (for example, it may be an international call). If you have more than one handset registered to your base unit, make sure that another handset isnt already using the line.
The Caller Display feature isnt working.
When I try to make a call, I hear Busy tone. The volume in the earpiece is low when Im on a call.
Make sure youre holding the earpiece correctly over your ear. Adjust the volume using the or button.
I cant transfer a call. Make sure the other handset is in range of the base unit. Make sure youre dialling the correct number for the other handset (1 to 4, or for all registered handsets).

Batteries

The handsets batteries are running low within an hour or two. Before you first used the handset, you should have left it on the base unit or charger pod for up to 15 hours to charge the batteries fully. You may need to replace the batteries (see below). Clean the battery charging contacts on the base unit with a dry cloth. Check the connections between the base unit and the mains power socket. I try to recharge the batteries, but I still get a warning that they are low. You need to replace the batteries. To find out how to obtain replacements, call 9677, between 9.00 am and 5.00 pm, Monday to Friday. Dispose of used batteries safely never burn them, or put them where they could get punctured. ALWAYS use the batteries supplied with your iDECT X2 other batteries may burst, causing damage.
