Adjustment of RF gain and muting level
Proper RF gain can facilitate to improve the quality of signal received. In general,
appropriately reducing the RF gain value at some low-frequency ranges with strong
interference can significantly improve the hearing.
Adjustment methods of RF gain:
1. Short press the volume knob to bring up the RF GAIN setting items. The tag on the
left side of the screen will display RF GAIN.
2. Rotate the volume knob to adjust the RF gain value.
SQL setting
When muting is necessary for signals or noise less than a certain amplitudes,
appropriate muting level can be set to disable the audio switch without signal so that the
speaker can be muted.
Operation methods:
1. Short press the volume knob to bring up the RFGAIN setting items. The tag on the
left side of the screen will display SQLLevel.
2、 Rotate the volume knob to set the muting level. At the same time, the muting grade
will display on the screen.

13
■ The muting grade gradually strengthens from S1 ~S9, corresponding to strength.
For example, when the muting grade is set to be S3, it indicates that the speaker will
sound when the signal strength is more than S3. Otherwise, the speaker will in the silent
mode.
Pre-amplifier/pre-attenuator
The pre-amplifier can improve
the receiving effect of some
weak signals of high frequency
range and the sensitivity of the
receiver.
Pre-attenuator can improve
barrage jamming caused by
strong signals and the
performance of receiver.

3. Short press [PRE] button again and no character will appear on the top of the screen,
indicating that the current state is shoot-through state.
■ Before they are used in frequency range less than 14MHz, disabling the
pre-amplifier is recommended so that the radio can be in the shoot-through state, which
is conducive to strengthen the front-end performance of the receiver and reduce the
influence of interference signals.
■ When the level displays that the received signals exceed _40dBm, turning on the
pre-attenuator is recommended to avoid the decreasing of the dynamics of the receiver
due to strong signals.
