N 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 the minimum signal
level needed to open the squelch. The attenuator function can
be deactivated in set mode.
± Rotate [SQL] clockwise past the 13 o’clock position to ac-
tivate the squelch attenuator.
• Attenuation level can be adjusted up to 10 dB (approx.) between
13 o’clock and fully clockwise position.
