The functions of keys of the transceiver unit and the remote station are almost the same. The table below shows the controls and keys for the transceiver unit.
Control
Function CHANNEL
(PUSH TO
ENTER) ? Selects a channel. ? Moves the cursor in menu opened. ? Registers selected item when pressed.
SQUELCH ? Mutes the receiver when no signal is present on
the channel selected.
? AUTO position automatically reduces white noise.
? With the SHIFT key is pressed, adjust the contrast of the
display.
VOLUME/POWER
? Turns the power on/off and adjusts the volume of the loudspeaker. Key Function
DISTRESS ? Transmits the distress alert after pressing three seconds.
When the key is pressed, the LED in the key blinks and the
buzzer sounds. Pressing the key three seconds
continuously the distress alert is transmitted and the LED
lights continuously and buzzer also sounds continuously.
These conditions are continued until the distress
acknowledge is received or you cancel the distress alert.
ALARM (INDICATOR)
? Blinks in red when a distress alert or urgent call is received.
Also, the acoustic alarm sounds. To stop the blinking and
silence the buzzer, press the CANCEL key.
? Blinks in green when a safety call or routine call is received.
The acoustic alarm sounds and stops automatically five
seconds later.
CANCEL ? Stops audible and visual alarms.
? Erases an error message.

1-51.1.3 Indications on the LCD
Below are all the indications which appear on the standby display on the transceiver unit.
Standby display on the transceiver unit Reference no.
Meaning 1
Displays the channel mode. (INTL / USA / WX / CANADA / INLND-WA / PRIV / (MEMO)) 2
SHIFT is displayed if the shift function is active. Or channel mode (for example CANADA) is displayed at the MEMO mode. 3
Displays the scan mode: SCAN, DUAL or no display. During the scan mode, channel indications are changed alternatively. No display means that the unit receives continuously on the same channel. 4
Lights when the loudspeaker is off. Goes off when the loudspeaker is on. 5 Displays the transmission output.
(Hi=25W / Lo=1W)
6 Displays reception signal strength by 4 steps.
1. No signal. Only antenna mark is displayed.
2. Less than 20 dB SINAD antenna mark and short bar
3. 20 - 40 dB SINAD antenna mark and two bars
4. 40 dB SINAD and more antenna mark and three bars
7 RX is displayed during reception and TX is displayed when
the RF signal detected at transmission state.
8 Displays the current channel.
PRIV channel: max three digits
