2. To disable the key press tone, press the push-to-talk switch to select "KP_MUTE". Then to enable the tone again,
select either "KP_ENAB" or "KP_LOCK" (see preceding section). Shortly after the desired mode is selected,
normal operation resumes.
Time-Out Timer
This transceiver has a Time-Out Timer feature which automatically disables the transmitter if it is keyed continu-
ously for longer than the programmed time. It is programmed by your system operator for a time from 0.5-5.0 minutes.
If this timer times out, the transmitter is disabled, the intercept tone sounds, and "TX TIME" is displayed. The timer and
tone are reset by releasing the push-to-talk switch. This timer prevents a blocked channel caused by an accidentally
keyed transmitter. It also prevents possible transmitter damage caused by transmitting for extended periods.
Voice Encryption
Optional voice encryption prevents your conversations from being monitored by casual eavesdropping or analog
scanners. It does this by encrypting your voice so that it can be understood only by someone using a transceiver
equipped with a similar encryption device.
To transmit an encrypted call, encryption must be manually enabled by pressing 2ND OPT. The display indicates
O
" " when encryption is enabled. To disable encryption, press SND OPT again. Encrypted calls are received even if
encryption is disabled; however, encryption must always be enabled to transmit an encrypted call. Encryption may need
to be disabled to dial a telephone number. Your system operator will provide more information if this is necessary.
Introduction
The remote control unit shown on the next page can be used to control the transceiver when the vehicular adapter
is being used. The vehicular adapter or charger accessories can be installed in a vehicle to allow this transceiver to be
converted to mobile use by simply plugging it into a special connector. The remote control unit enhances operation of
the vehicular adapter by making the transceiver controls more accessible. Contact your system operator for more infor-
mation on these optional accessories.
Control Unit Controls
PWR - Turns both control unit and transceiver power on and off. Power may also be controlled by the vehicle's
ignition switch. Therefore, that switch may need to be on to turn power on. The transceiver on-off/volume control
is non functional when the control unit is used with the vehicular adapter.
VOLUME - Pressing the upper Volume switch increases the volume level by one step, and pressing the lower switch
decreases the volume level by one step. Holding either switch down causes the function to repeat. The volume level
is indicated by a bar graph on the right side of the display.
