Rotary Switch
NOTE
For purposes of this manual, assume that the rotary switch will always be in the
NORMAL position.
NOTE
If the position of the rotary switch must be changed, as in servicing, it is imperative
that the Operator observe the light in the corner of the Rotary Switch panel before
making any change. The switch position may be changed only if the light is green.
Never move the switch if the light is red. Instead, call the Dual-Lite System Services
technician.
NOTE
The LED light is positioned in the lower left-hand corner.

NOTE
The manufacturers of the valve-regulated batteries supplied with Dual-Lite’s standard
battery cabinets recommend that when first installed the batteries be equalize
charged. After that initial equalize charge, they recommend no further equalize
charging for their batteries. Other manufacturers may have different
recommendations for their products. Consult the battery manufacturer’s manual for
specific information about equalize charging.
