TS+

Increase frequency step

 

This moves the frequency marker from right to left. When it gets to the far left it wraps around to 
the lowest digit. When you turn the frequency knob clockwise, you increase the frequency based on 
the frequency step you are under. When you turn the frequency knob counter clockwise, you 
decrease the frequency based on the frequency step you are under.

 

 

TS-

Reduce frequency step

 

This moves the frequency marker from left to right. When it gets to the far right it wraps around to 
the highest digit. When you turn the frequency knob clockwise, you increase the frequency based 
on the frequency step you are under. When you turn the frequency knob counter clockwise, you 
decrease the frequency based on the frequency step you are under.

 

 

ATT

Switch receive signal attenuator on or off

 

When the attenuator is on, the signal is attenuated about 10 dBm. You would typically keep the 
attenuator on when you are trying to listen to a very strong signal or there are strong signals around 
the frequency you are listening to. Keep the attenuator off if you are trying to listen to very weak 
signals. When the attenuator is on, there is a small ATT indication on the top left of the screen.
