MODES OF OPERATION: 
 

The AR2 uses an advanced way to access the many useful features built in to 
the unit. What looks like a volume control at first glance is actually a jog dial. 
No, it doesn’t go for a jog at the end of a long work day, instead it allows you 
to enter values digitally in a convenient way. 
 
There are a few modes of entry of using the jog dial: 

a. 

Turn clockwise and counter clockwise 

 

b. 

Press the knob and turn

 

c. 

Press the knob briefly

 

d. 

Press and hold.

 

 
By pressing and turning the knob you can select the various modes of 
operation of the AR2. As you turn the knob while holding it in, the display will 
show the current selected mode. Release the knob to choose that selection.  
 
The modes are as follows: 
 
1. 

Normal receive mode

. This mode operates much like the old AR1, 

allowing the jog dial to select frequencies within the aircraft band to listen 
to. The display shows both frequency and the field strength of the signal 
(RSSI). 

2. 

Lighting Control Mode. 

This mode allows a user to access an external 

circuit to remotely control runway lights in small airports by keying the 
radio at the frequency to which the AR2 is set. 

3. 

Full Scanner Mode. 

This mode operates like normal receive mode but 

will scan for the next frequency that opens the squelch when you press 
the knob briefly. 

4. 

Scanner 1 Mode. 

This mode allows you to scan up to 20 frequencies 

saved in the Scanner 1 Setup mode. 

5. 

Scanner 2 Mode. 

This mode allows you to scan up to 20 frequencies 

saved in the Scanner 2 Setup mode. 

6. 

Scanner 3 Mode. 

This mode allows you to scan up to 20 frequencies 

saved in the Scanner 3 Setup mode. 

7. 

Scanner 4 Mode. 

This mode allows you to scan up to 20 frequencies 

saved in the Scanner 4 Setup mode. 

8. 

Scanner Skip Mode. 

This mode operates like Mode 2, except that it skips 

automatically to the next active frequency after a specified period of time 
that you’ve preset in the skip timer setup screen. 

9. 

Skip Scanner 1 Mode. 

This mode allows you to scan up to 20 

frequencies saved in the Scanner 1 Setup mode, only this will
