will be transmitted on the HOME channel instead
of the elected channel.
If the radio is scanning when the
∧
button is
pressed and no HOME channel is programmed, the
radio will stop scanning, transmit the emergency
ANI code on the selected channel, and resume
scanning. If the radio is scanning when the button
is pressed and a HOME channel is programmed,
the radio will stop scanning, transmit the emer-
gency ANI code on the HOME channel, switch the
receive operation to the HOME channel, and re-
sume scanning.
Emergency transmissions can only be disabled by
turning the radio off and then back on.
BACKLIGHT - In 2-channel radio operation, this
button illuminates the backlight. BACKLIGHT
will be illuminated when the button is pressed and
will remain on for 5 seconds after the button is re-
leased (provided the button was pressed for at least
one second).
∨
In 8 and 16 channel radios, while the "S" button is
being pressed, activating the
∨
button will remove
(delete) the selected channel from the Scan list.
Radio operating status is not altered when this but-
ton is activated alone.
In the 2-channel radio, this button toggles the TX
power between 2 and 5 watts.
CHAN
UP/
DOWN The CHAN UP/DOWN button selects the trans-
mit/receive channel. Communications channels
are selected one at a time or progressively by
pressing and holding the CHAN UP/DOWN but-
tons. The next higher channel is always selected
(channel 1 follows channel 2, 8, or 16 for 2-, 8-, or
16-channel radios respectively).
VOL
ume The VOLume buttons set the receive audio to the
desired level while pressing the UP or DOWN but-
ton. Changing the volume level while the radio is
squelched causes the radio to beep, if programmed,
at the new selected level. No beep will sound
when the radio is already unsquelched. The rela-
tive volume level is indicated by the number of
bars illuminated in the LCD. There are eight (8)
levels of volume indicated by the four (4) bars on
the LCD; each bar represents two levels of volume.
Pressing and holding the volume buttons continues
to increment the volume in the direction indicated
on the button.
INDICATORS
The LCD shows the SCAN mode (for 8 and 16 channel
radios only); P1, P2, and S (Scan list) indicators; channel
number; volume level; battery condition; Type 99 Tone de-
code status; and transmit indicator (see Figure 2). With re-
gards to 8 and 16 channel operation, the LCD is backlit
anytime a control button is pressed. Backlighting is always
turned ON during transmit and remains on for 5 seconds af-
ter the PTT or control button is released, if programmed.
In the 2-channel radio, the high and low power are indi-
cated by the "P1" and "P2" pixels, respectively, and the "S"
pixel indicates the radio is in "Talkaround" mode.
The LCD indicators are shown below in the transmit and
receive mode.
Transmit Mode
TX TX indicates transmit mode when the PTT button
is pressed.
BAT BAT indicates battery voltage is low and the bat-
tery pack requires charging. when the battery pack
voltage reaches the low level while in the transmit
mode, BAT is illuminated and stays illuminated for
another 5 seconds after the radio is returned to the
receive mode. BA is turned off after five seconds
unless the battery pack voltage level is also low in
the receive mode.
Receive Mode
VOL The volume level (eight different levels) is indi-
cated by 4 bars on the LCD; each bar represents 2
volume levels.
PG This display indicates the selected channel pro-
grammed to receive Type 99 calls. Upon receipt of
a Type 99 call, the PG flag flashes until the Type
99 call decoder is reset.
The short beep indicator on volume change will
not be sounded when the speaker is already on.
