AUXILIARY FUNCTIONS
TIME-OUT TIMER (TOT)
Time-out Timer is to prevent the use of the same channel for too long and the radio from energy waste due to
continued transmission.
If the radio continuously transmits signals for a period over the preset limit (set by your dealer, max time is 5
minutes), the transceiver will stop transmitting and a beep will sound. To stop the tone, release the PTT button
.
Press the PTT button again to resume transmission.
Battery Save
This function minimizes the amount of power used when a signal is not being received and no operations are
being performed (no keys are being pressed).
While the channel is not busy and no operation performed for 10 seconds, Battery Save turns ON. When a
signal is received or an operation is performed, Battery Save turns OFF.
LOW BATTERY WARNING
Low Battery Warning alerts you when the battery needs to be recharged.
While transmitting, if power of the battery goes below a pre-determined value, the red light will flash, a tone
sound, and the radio will stop transmitting. Please replace or recharge the battery.
MONITOR
The squelch circuit on the radio automatically mutes the speaker when there are no signals, eliminating
background noise.
Press and hold "CH UP" key to manually deactivate the squelch mechanism. This
operation is especially useful for adjusting volume level or receiving a weak signal.
CTCSS & DCS
Some channels may have pre-programmed CTCSS/DCS tones. A CTCSS/DCS tone is a sub-audible signal,
which allows you to ignore (not hear) calls from other parties using the same channel.
When you receive a signal that has a tone different from the one set up in your radio, you will not hear the
signal. Likewise, signals that you transmit will only be heard by parties whose CTCSS/DCS tone matches the
tone set up in your radio.
NOTE Although using channels set up with CTCSS/DCS tones enable you to avoid hearing those unwanted
calls, it does not mean your calls will be private.
TROUBLESHOOTING
See below for some common problems and their remedies. DO NOT attempt any repairs yourself. This will
invalidate your warranty.
PROBLEM POSSIBLE CAUSES / REMEDIES
Can’t turn the radio on
● Check the battery is correctly installed and has been fully
charged
Can’t communicate with other
radios
● Check the channel and CTCSS code
