Transming
To transmit:
1. Press and hold the PTT (Push-To-Talk) switch. The other radio you are talking to must be
set to the same channel.
2. Hold the radio approximately 5-8 cm from your mouth with the antenna vercal and
speak into the built-in microphone.
3. While the PTT switch is pressed, the LED indicator on the upper edge of the radio will
light red and the
icon will appear on the LCD.
4. When you have nished speaking, release the PTT switch to receive incoming signals (it is
not possible to transmit and receive at the same me). If no further signals are received,
the unit will revert to ‘Standby’ mode.
The PTT switch can also be used to transmit a Call Alarm Melody.
When the call alarm melody is enabled (see Menu opons for more details on
Call Alarm sengs), pressing the PTT switch twice quickly will play the call alarm melody in the
speaker of other radios on the same channel to alert them to your call. During this me the
icon is displayed and the LED indicator will light red for about 5 seconds. The call alarm can
only be sent once per minute.
Time-out Timer
The radio has a built-in me-out mer that automacally limits transmissions to a maximum of
3 minutes of connuous operaon. This feature is required by the ACMA to prevent accidental
blocking of the frequency should your PTT switch become jammed or be otherwise pressed
accidentally. When the me-out mer acvates, the radio will beep and ‘tot’ is displayed briey on
the LCD. Normal operaon will be restored once the PTT switch is released.
Selecng Channels
1. In the ‘Standby’ mode, press the key to step up one channel or the key to step down
one channel.
2. Press and hold the or keys to quickly scroll through the channels.
Squelch
The Squelch is used to eliminate the background noise when there are no signals present. When
the squelch is open the receiver’s background noise can be heard. When the squelch is closed the
receiver remains quiet while there are no signals present but any incoming signals will override the
squelch and be heard in the speaker.
To open the squelch:
Briey press the SQL key. This will allow you to check the current channel for acvity before
transming, parcularly if you have CTCSS/DCS enabled.

will appear on the display. Adjust the Volume control for a comfortable listening
level.
If the incoming signal is encoded with a CTCSS or DCS tone matching the one set
in your radio, the LED indicator will light orange and you will be able to hear the
signal in the speaker. If the LED indicator lights green and the
