8. Troubleshooting
A. The battery power may be insufficient. Please recharge or replace the
battery pack.
B. The battery pack may not be installed properly. Please remove the
battery pack and install again.
A. The battery life is finished. Please replace it with a new battery pack.
A. Make sure the CTCSS/DCS signal is the same as that of your group
members.
B. The radio is out of effective communication range.
A. Change the CTCSS/DCS signal, and make sure to change the
CTCSS/DCS signal of all radios in your group.
Causes and Solutions
Problem
The radio cannot be
switched on or no display
after being switched on.
The battery power
consumes quickly after
charging.
Cannot talk to or hear
other group members.
Other voices from non-
group members are heard
on the channel.
No.

used to notify the identity of the callers to the
monitoring center, or used to activate the repeater.
The encoder sequence and the encoder type can be
set for each channel. There are 16 groups of
sequences for your selection.
PTT ID Keydown Code: The radio will send DTMF
sequence when the PTT button is pressed.
PTT ID Dekey Code: The radio will send DTMF
sequence when the PTT button is released.
7.6 CTCSS/DCS
CTCSS/DCS tones may have been pre-programmed
on some radio channels. A CTCSS/DCS tone is a
sub-audible tone, which allows you to ignore (not
hear) calls from other irrelevant parties who are using
the same channel. When you receive a signal that
has a tone different from the one set on your radio,
you will not hear the signal. Likewise, signals that you
transmit will only be received by parties whose
CTCSS/DCS tones are the same as yours.
Note: Using a CTCSS/DCS channel doesn't mean
your calls are private. If other parties' CTCSS/DCS
tones are identical with yours, they can hear your
calls.
7.7 PTT ID
PTT ID uses DTMF code. The preset DTMF
sequence can be sent at the beginning of the
transmission or at the end of the transmission. It is
monitoring state.
