Squelch Setting

SQ_SQ: Signal strength monitoring squelch setting
This function is used for squelch level setting, but it detects the strength of received signal, and
better strength means a better signal. It is divided into 29 levels (0.F~2.8), 0.F is the lowest level,
and 2.8 is the highest level. For example, when set to 2.8, the audio channel can only be turned
on when the received signal reaches its maximum. (In an experiment, the noise adjustment
range of SQ_SQ is obviously larger than SQ_AQ. We recommend using SQ_SQ as the first
choice, as SQ-SQ and SQ-ASQ can't work at the same time. One will stop working when the
other one is running.)
Operation instructions:
1. Enter: short press the SQ button, the screen displays "sq" for one second, and then display
the current SQ level. At this time, the SQ level can be adjusted by pressing UP and DN.
2. Exit: After the adjustment is completed, you can press SQ again to exit the SQ setting mode,
or you can automatically exit the SQ setting mode and enter the waiting mode. Keep it for a
while without any operation will also exit the SQ setting..
SQ_ASQ: Noise monitoring squelch setting.
This function is also used for squelch level setting, but it detects the noise of received signal,
and the smaller the noise, the better the signal. It is divided into 9 levels (A1~A9), A1 is the
lowest level, and A9 is the highest level.
Operation instructions:
1. Enter: Long press the SQ button, the screen displays the AQ icon and the current ASQ level.
Short press the SQ button or wait for a while, back to waiting mode, the AQ icon will still light
up. When SQ_ASQ is in waiting mode, short press SQ will return to SQ_ASQ setting status.
2. Exit: When the SQ_ASQ function is on, long press SQ will exit.

Modulation Selection

Depending on the selected frequency range and the selected channel, the device supports FM
(Frequency Modulation) and AM (Amplitude Modulation) modes.
Long press [A/F] key to select AM mode and FM mode. However, such a change is only possible
if the set channel is also allowed in the respective operating mode.
for European version.
The respective operating mode is indicated on the LC display with "AM" or "FM" to the left of the
channel number.

RF Gain Control Function

This function will affect the strength of signal reception.
1. Enter: short press [RFG] key to enter. After entering, the screen will display current RFG level,
you can press [UP] and [DN] keys to adjust RFG level. The RFG level is not a continuous
number but "6", "12", "18", "24", "30", "36", "42", "48" a total of 8 levels. When the RFG function
is turned on, the signal reception intensity will be attenuated. The higher the level is, the
