1. Menu/Execute - Any change to the programming of the  unit must be initiated by pressing 

the Menu/Execute switch and completed by pressing the Menu/Execute switch.

2. Horizontal Switch - This switch is mounted so its movement is horizontal and moves the cursor 

left or right.  

3. Vertical Switch - This switch is mounted so its movement  is vertical and has two functions:

a. During gain changes, the vertical movement will raise or lower the number in the direction 

of the arrows.

b. For other functions such as Remote Mode, the vertical switch will cycle through the different options.
