3.3.7 BANK SELECT
Two banks of up to 16 channels each can be pro-
grammed. Only the channels in the current bank are
then selectable. This would allow, for example, groups
of channels to be programmed for operation in differ-
ent cities.
The key is pressed to switch between
banks, and the current bank is indicated briefly in the
display as “BANK 1” or “BANK 2”. If bank select is
not used, a single block of up to 32 channels can be
programmed.
3.3.8 AUTOMATIC SCAN ENABLE
The transceiver can be programmed so that scan-
ning is automatically enabled whenever power is
turned on or the microphone is placed on-hook. Refer
to the scan description in Section 3.6 for more
information.

The following backlight modes can be selected
by the option switch or by pressing F3 in the
power-on menu described in Section 3.3.4.
LI ON - On continuously
LI OF - Always off
LI AT - Controlled by the voltage applied to pin 1
of the DB9 connector on the optional accessory
cable (see “Light” in Table 4-2).
3.3.10 BEEP ON-OFF
The key beep which sounds when keys are
pressed can be enabled and disabled by pressing the
option switch or pressing F2 in the power-on
menu described in Section 3.3.4. Either “BP ON” or
“BP OF” is displayed to indicate the current mode.
3.4 RECEIVING AND PLACING CALLS
3.4.1 INTRODUCTION
The two calls which can be placed and received
are mobile-to-mobile and telephone calls. With tele-
phone calls, the telephone number can be dialed using
a microphone with a telephone keypad, or up to seven
telephone numbers also may be preprogrammed and
then selected by pressing the
key (see descrip-
tion in Section 3.5.7).
3.4.2 RECEIVING A CALL
1. Turn transceiver power on and set the volume level
as described starting in Section 3.3.1.
2. Select or scan the channel or channels on which you
want to receive the call. Refer to Section 3.6 for
more information on scanning.
3. When the message is received, take the microphone
off-hook and respond. Press the microphone push-
to-talk (PTT) switch to talk and release it to listen.
4. When the conversation is finished, place the micro-
phone back on-hook. The microphone hanger may
control features such as scanning and monitoring
that are described later.
3.4.3 PLACING A CALL
1. Turn transceiver power on and set the volume level
as described starting with Section 3.3.1.
2. Select the channel on which the call will be made as
described in Section 3.4.
3. Regulations require that the channel be monitored
before transmitting to make sure that it is not being
used by anyone else. If you were to transmit while
someone was talking, you would probably disrupt
their conversation. Refer to “Monitoring Before
Transmitting” description which follows for more
information.
4. If the channel is not busy, press the microphone PTT
switch to talk and release it to listen.
