BASIC OPERATION

Squelch attenuator
The transceiver has an RF attenuator related to the squelch
level setting. Approx. 10 dB attenuation is obtained at maxi-
mum setting.
The squelch attenuator allows you to set a minimum signal
level needed to open the squelch. The attenuator function can
be deactivated in initial set mode.
➥
Rotate [SQL] clockwise past the 12 o’clock position to ac-
tivate the squelch attenuator.
• Attenuation level can be adjusted up to 10 dB (approx.) between
12 o’clock and fully clockwise position.
• When setting the squelch from the microphone, a level greater
than ‘19’ activates the squelch attenuator.
NOTE:
The squelch attenuator functions even when the
monitor function is in use. Thus set the [SQL] control within
10 to 12 o’clock position is recommended when using the
monitor function.
