1. ANL-OFF 

Selector 

This selector enables the ANL function (Automatic Noise Limiter). The ANL reduces electric and electromagnetic noise on the 
operating frequency. Move the selector to ANL to enable the Automatic Noise Limiter and move it to OFF to disable it. 

2. LOC-DX 

Selector 

This selector enables the LOC function (Local), in order to attenuate the strength of the incoming signals. The attenuator is useful in 
case of very strong incoming signals from local stations that, due to the high signal level, might cause distortion and poor quality of 
the received signals. Move the selector to the DX (Long Distance) when receiving weak signals or from long distance. Move the 
selector to LOC (Local) when receiving strong signals from local stations. 

3. LCD 

Display 

Large size (visible area mm 54 x 21) LCD display with orange colour backlighting system, for best readability. The LCD display 
shows all the enabled functions as well as several other information and user programmable functions, like the full 5-digit frequency 
readout. LCD also includes a digital 10-bar S/RF Meter to monitor the strength/power of the received and transmitted signals.
