TRANSCEIVER OPERATION

December 1997
Part No. 001-7500-001
2.3.6 ADJUSTING VOLUME
To adjust the volume, rotate the on-off/volume
control while a message is being received. To adjust
while no message is being received, press and hold the
Monitor switch (if programmed, see Section 2.5.6).
This enables background noise for use as a reference
level. Otherwise, note the position of the index on the
knob.
2.4 BASIC OPERATION
2.4.1 RECEIVING A CALL
1. Turn power on and set the volume as described in
Sections 2.3.4 and 2.3.6.
2. Select the desired channel using the
▲ ▼
switches.
The transceiver is now set to receive a message on
that channel.
2.4.2 TRANSMITTING A CALL
CAUTION
Do not transmit without an antenna because trans-
ceiver damage may result. Antenna attachment is
described in Section 2.3.2.
1. Turn power on and set the volume as described in
Sections 2.3.4 and 2.3.6.
2. Wait for the channel to become clear to avoid inter-
ference (see “MONITOR” description in Section
2.5.6).
3. Push and hold the PTT switch on the side and speak
into the microphone at a normal voice level.
NOTE: If a selective calling feature is being used (see
Section 2.4.5), it is recommended that you pause for a
moment before speaking after pressing the PTT
switch. This gives the receiving transceiver time to
detect the call which prevents the possible loss of part
of your first word.
4. Release the PTT switch as soon as your message is
complete so that a response can be received.
2.4.3 LOW BATTERY INDICATION
When a low battery condition is detected,
is
displayed continuously. The battery will require
recharging soon.
When battery capacity is nearing the minimum
level needed to operate the transceiver,
begins
flashing.
2.4.4 TIME-OUT TIMER
This function disables the transmitter if it is
keyed continuously for longer than the programmed
time. This prevents possible transceiver damage
caused by transmitting for excessive periods and also
a channel from being blocked for an extended period
by an accidentally keyed transmitter.
A penalty timer may also be programmed which
inhibits the transmitter for a fixed time after the time-
out timer is activated.
2.4.5 SELECTIVE CALLING
Introduction
If your transceiver utilizes a selective calling sys-
tem of some type, it may be necessary to select the
particular station to which a call is to be placed or
from which a call is to be received. The general proce-
dure is as follows:
1. Select the transmit code channel or 5-tone code (see
following).
2. Press the switch programmed for the call function.
3. After transmitting a 5-tone code, the remainder of
the call can be carried out in the normal manner.
Transmit Code Channels
Your transceiver may be programmed so that a
transmit code channel is selected when using the call
function just described. To activate this function, press
the switch programmed for transmit code channel
selection. Then enter the number of the desired trans-
mit code channel using the number keypad. The call
