RECEIVE
CTCSS /CDCSS/ DTMF/Two-Tone functions are programmed by the factory or your dealer.
When signaling tones have been programmed, only channels with the same frequency and
signaling tones can be heard. If tone signaling is not used, then all conversations on your selected
channel can be heard.
TRANSMIT
Before transmitting, verify there is no channel activity. Push the PTT button and speak clearly
into the microphone (mouth is 1 – 2 inches away from the microphone); or push a key on the
keypad to transmit a DTMF tone. When the
PTT button is released, the radio returns to receive
mode.
NOTE:
•
If your dealer has enabled Busy Channel Lockout feature and the selected channel is
busy, when pressing the
[PTT]
button, the radio will sound an alert tone and the
transmission is prohibited.
•
When pressing the [PTT] button, the radio will check its battery voltage. If the battery
voltage is lower than the “low battery” threshold value, the red LED flashes. If the
voltages drops further, the radio stops transmitting and an alert sounds. In this condition,
recharge or replace the battery with a charged battery.
•
When continuous transmission time exceeds the preset time of the “Time-Out-Timer”
(programmed by the dealer), the radio stops transmission and an alert sounds. The unit
then returns to the receive mode. Also, a “Transmit Warning” alert tone can be
programmed by the dealer to warn the end user that the transmission time is becoming
long.
SELECT TRANSMIT POWER
If transmit power (programmed by the dealer) is set to “high” on any given channel, pressing
the
[LO] key will toggle the transmit power modes between “high” and “low”. When in low
power mode, “Lo
”
appears on the LCD. Since using low transmit power mode can save
battery life and decreases potential interference to others, low transmit power mode should be
selected when the communication quality can be guaranteed.
NOTE:
•
If “high” transmit power is prohibited on the current channel and “Lo” is displayed on
LCD, when pressing [LO], an alert tone of wrong operation will be heard and the
transmit power will remain “low”.
•
The operation of switching a channel from “high” transmit power mode to “low”
transmit power mode will switch all channels from “high” transmit power mode to
“low“ transmit power mode.
CONNECT ID/DISCONNECT ID
When the radio is connecting or disconnecting to a repeater, a connect ID or disconnect ID
(programmed by your dealer) can be sent. One of the following methods can be configured:
To transmit a connect ID:
