ACCESSORIES

6.1 BATTERY PACK MODULE (OPTIONAL)
The battery pack module is a field-installable assembly that provides
approximately eight hours of uninterrupted operation. A monitoring circuit
ensures that the two 12V batteries charge within 12 hours and then switch to
trickle charge to ensure maximum charge without battery damage. An alarm
warns the operator when batteries are low.
