Safety precautions W

Read this manual and the safety precautions carefully before use. Explain their contents to your children, and the potential hazards associated with using the telephone. Only use the mains unit supplied.
Do not install the phone in a bathroom or shower room as the handset and base are not splash-proof. (page 7) Do not use the telephone in environments subject to explosion hazard (e.g. auto paint shops).
If you give your Gigaset to someone else, make sure you also give them the operating manual.
Fit only the approved rechargeable battery pack! Never use a conventional (non-rechargeable) battery pack as this could damage your health and cause injury. Use the battery pack as directed in these instructions (page 7). The operation of medical appliances may be affected. Be aware of the technical conditions within the particular environment (e.g. doctor's practice). The handset may cause an intrusive 'hum' in hearing aids. Do not hold the handset against your ear while it is ringing (incoming call).
Dispose of the battery pack and telephone in accordance with environmental regulations.
Do not pollute the environment. Emergency numbers cannot be dialled if the keypad lock (page 3) is activated! Not all of the functions described in this manual are available in all countries.
Setting up the telephone for use
Step 1: Connecting the base
Step 3: Registering the handset to the base and charging the battery pack
Place your handset in the base with the display facing forwards. The handset will now register automatically to the base. For procedure see page 4.
Charging the battery pack
Connect the phone jack with the phone cord 1 and the mains units (230 V) with the power cord 2 as shown. Place the cords in the cord recesses. The two cords must be plugged in at all times. Use only the mains unit supplied (see the bottom of the base). If you ever purchase another phone cord from a store, ensure that the phone conductors are correctly connected: 3-4 connection of the telephone conductors/EURO CTR37. The range may be affected if the telephone is wall mounted.
To charge the battery pack, leave the handset in the base for approx. ten hours. The battery pack is now fully charged. The charge status of the battery pack is correctly displayed only after uninterrupted charging/discharging. You should not therefore interrupt the charging process. Charging is electronically controlled to prevent overcharging. The battery pack heats up during charging; this is normal and not dangerous. After a time the charge capacity of the pack will decrease for technical reasons. You must set the date and time to ensure that the times of calls are logged correctly (page 9). Your telephone is now ready to use.

Activating/deactivating the handset
Press the 'end call' key a and hold. If you place a deactivated handset in the base station or charger, it will automatically activate.

Plug the jack firmly into the socket (see picture on right). To close the battery compartment, position the cover and press until it snaps home.
Only insert the recommended rechargeable battery pack, i.e. never use a normal battery pack as this could damage your health and cause injury. Never use non-Siemens battery chargers as this could damage the battery pack.
