DIFFICULT RECEIVER CONDITIONS

Receiving signals under difficult conditions.

1.

High Sensitivity

Press 

 to increase the Sensitivity by approx. 5dB.

The HiSens annunciator is on when High Sensitivity is
selected.The HiSens should be used if very weak signals
are receiced.

High Sensitivity is switched off by pressing 

 once more.

2.

Antenna Attenuator

Press 

 

 

 to switch on and off

the receiver Antenna Attenuator. The Att annunciator
is on in the display when the Antenna Attenuator is
switched on.
The Antenna attenuator should be used when strong
interferring signals are present at the receiver antenna
input.

Strong interferring signals may distort the wanted signal by overloading the receiver input.
