Figure 3 – Option Select (DIP) Switch Diagram 

 

A switch is “On” when it is pointing in the direction of the arrow 
AWAY FROM the switch numbers, and “Off” when it is pointing 
TOWARDS the switch numbers. 
 
The diagram above is for illustrative purposes only—your actual 
switch settings will vary. 
 
Switch settings are read only at the moment power is turned on. 
Therefore, any changes made to the switch settings while power 
is on do not take effect until the power is recycled.
