Button 6: Squelch , Mic Gain, RF Gain, Repeater control

The squelch is used to eliminate background or "white" noise when monitoring strong
signals. To activate the squelch control press "SQ, MICG, RFG/RPT" button and then use
the "up" and "down" button to set the desired point where the background noise is just
eliminated.
MIC-G (MIC-Gain) : When activated, the MIC-G feature actually adjusts the microphone gain
in the transmit mode, On the unit activating the MIC-Gain feature would have its best
application when the user has a very strong, "booming" voice tone that would create a
distorted signal going into the microphone, because this situation will only occur in rare
situation. Mic-Gain feature in maximum position give the user to its maximum sensitivity.
•
To Turn-On, press "SQ, MICG, RFG/RPT " 2 times until the word 'MC-G" will
appear on display. Then use the "up "and "down" button to increase and decrease
microphone amplifier gain.
RF-G (RF Gain): Allows optimizing the incoming signal gain.
•
To activate, press "SQ, MICG, RFG/RPT" button 3 times until the word "RF-G"
appear on the display. Use "up" and "down" button to increase and decrease the
receiver sensitivity.
Activating the "RF-G" feature helps to attenuate very strong signals that are produced from
another radio that is in very close proximity to the unit. Turning this feature to maximum
position creates full receiver sensitivity.
RPT: Repeater access tone on and off control
Most USA repeaters require an 88.5 Hz CTCSS tone to access.
•
To activate the 88.5Hz CTCSS tone press "FUNC" and then "SQ, MICG, RFG/RPT ".
