Using the Attenuator
The attenuator reduces the amount of signal at the receiver input (20 dB) and may help reduce interference from strong nearby transmitters. There are two attenuation modes, Normal and Global. Normal attenuation uses the attenuation settings for each object or search. Global attenuation forces attenuation for all objects, on or off
To Attenuate a Conventional Object press ATT anytime a conventional object is in the display.
To Attenuate a Trunking System press ATT anytime a talkgroup object is in the display.
To Attenuate a Search Object or Dedicated Search press ATT during the search.
Personally if someone asks my help programming I do a FUNC ATT to turn off the G since with the G on, too easy for someone to accidentally push the ATT button that would kill reception with the attenuation actually on. Then someone would ask why there radio is not picking anything up?
