TX6160 INSTRUCTION MANUAL
18
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 ashes but you cannot hear the signal, it is likely that the incoming signal is
using a dierent CTCSS or DCS tone to that selected in your radio (see Menu options for more details on
setting CTCSS/DCS tones).
If no further signals are received, the unit will return to standby mode after a few seconds.
TRANSMITTING
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 vertical 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 time). If no further signals are received,
the unit will revert to Standby mode.
Note: The PTT switch can also be used to transmit a Call Alarm melody.
When the Call Alarm melody is enabled (see Menu options for more details on Call Alarm settings), 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 time 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 time-out timer that automatically limits transmissions to a maximum of 3
minutes of continuous operation. This feature is required by the ACMA to prevent accidental
blocking of the frequency should your PTT become jammed or be otherwise pressed accidentally.
When the time-out timer activates, the radio will beep and “tot” is displayed briey on the LCD. Normal
operation will be restored once the PTT is released.
