BATTERY PACKS AND ACCESSORIES

s About the battery pack

D Operating period
Depending on the attached battery pack, the operating period of the transceiver varies. Refer to p. 28 for battery pack specications.

s Battery pack charging

The supplied* BP-180 BATTERY PACK includes rechargeable Ni-Cd batteries and can be charged approx. 300 times. Charge the battery pack before rst operating the transceiver or when the battery pack becomes exhausted.
*Optional for versions which come with the BP-170 BATTERY CASE.
If you want to be able to charge the battery pack more than 300 times, the following points should be observed: 1. Avoid overcharging. The charging period should be less than 48 hours. 2. Use the battery until it becomes almost completely exhausted under normal conditions. We recommend battery charging just after transmitting becomes impossible.

BATTERY CASE is connected, otherwise the battery may leak and damage the transceiver.
Open the case. CP-12L (optional)
To a cigarette lighter socket OPC-254L (optional) white black To a 4.5 to 16* V DC power source Install 4 AA(R6) size dry cell batteries into the battery case.
*To charge the battery pack 12 to 16 V DC is necessary.

s Accessory attachment

D Antenna
Insert the supplied antenna into the antenna connector and rotate the antenna as shown in the diagram below. Keep the jack cover attached when jacks are not in use to avoid bad contacts.

s Subaudible tone operation

D Tone squelch operation

The tone squelch opens only when receiving a signal containing a matching subaudible tone. You can silently wait for calls from group members using the same tone.
SET MODE D Setting subaudible tones for tone squelch operation (CTCSS tones)

Push [(VFO)CLR] to exit set mode.
Operate the transceiver in the normal way. To cancel the tone squelch, push [TONE].
NOTE: The transceiver has 50 tone frequencies and consequently their spacing is narrow compared with units having 38 tones. Therefore, some tone frequencies may receive interference from adjacent tone frequencies. CONVENIENT Store subaudible tone frequencies and tone squelch ON/OFF settings in memories (call) for easy recall.
ADVANCED FUNCTIONS D Tone scan
The transceiver can detect the subaudible tone frequency in a received signal. By monitoring a signal, such as that being transmitted on a repeater input frequency, you can determine the tone frequency required to access the repeater.

D Pocket beep operation

This function uses subaudible tones for calling and can be used as a common pager to inform you that someone has called while you were away from the transceiver.
Set the operating frequency. Set the desired subaudible tone (same as that used for
tone squelch operation, CT) in set mode.
See p. 21 for programming.
Set the desired frequency or memory channel to be
checked for a tone frequency.
Push [T SCAN] for 1 sec. to start the tone scan.
To change the scanning direction, rotate [DIAL].
Push [TONE] two times until TSQLS appears. When a signal with a matched tone is received, the transceiver emits beep tones for 30 sec. and ashes S.
When the tone frequency is decoded, the set mode contents are programmed with the tone frequency.
The decoded tone frequency is used for the tone encoder or tone encoder/decoder, depending on the the tone squelch ON/OFF setting. CT or rT appears during tone scan when the tone squelch is in use or not, respectively.
Push [PTT] to answer or push [VFO] to stop the beeps and
