Battery save function can decrease the battery power consumption.
Low Power Warning
Low power warning tone sounds and LED flashes red when the battery power goes below the
preset value and you need to recharge the battery. In low battery status transmission is prohibited.
Channel Annunciation
The dealer can activate or prohibit this function. Two types of Chinese and English annunciation
are available.
When switching to a channel by rotating the channel knob, the current channel number will sound.
CTCSS/DCS
The dealer can set CTCSS/DCS on the radio channels to ignore calls on the same channel from
irrelevant radios.
If a channel has been set with CTCSS/DCS, the squelch will be activated only when it receives the
proper CTCSS/DCS signals. And only the radios set with the same CTCSS/DCS signaling as
those on yours can hear your call.
Note: Using a CTCSS/DCS channel doesn’t mean your calls are private. If the CTCSS/DCS tones
of other radios are identical with those on yours, they can hear your calls.
User Solution
A user solution includes PTT code-transmitting, encoding, decoding, Busy Channel Lockout, Call
1/2, SP un-mute, and decoding conditions, etc. Maximum 32 user solutions are available on this
radio.
a) An encoding template consists of at least one and at most 3 encoding sequences. The setting of
each sequence has options 5-Tone, 2-Tone, and DTMF. If it is set at 5-Tone or DTMF, you need
to program its content. If it is set at 2-Tone, you need to program two frequencies. After setting
the encoding templates, the dealer can choose one of these encoding templates as the user
solution.
b) The decoding templates are divided into 5-Tone decoding templates and 2-Tone decoding
templates. Only when the decoding template is identical with the encoding template, it can
decode successfully.
Busy Channel Lockout (BCL)
Busy Channel Lockout can prevent you from interfering other radios using the same channel.
If you press the PTT button when the channel is busy, the radio with BCL function active will
make warning sound and transmission is prohibited. To stop the warning sound, please release the
PTT button and the radio will return to receiving mode.
The dealer can set one of the following BCL types:
1) OFF: BCL is inactive and you can transmit on the busy channel.
2) Carrier wave: If carrier wave is detected, the radio is unable to transmit.
3) CTCSS/DCS: The radio is allowed to transmit when the CTCSS/DCS signalings are identical.
4) Selective signaling: The radio is allowed to transmit when the selective signalings (2-Tone or
5-Tone) are identical.
