TM 9-2350-287-10
OPERATING AUXILIARY EQUIPMENT (continued)
Operation and Maintenance
For general operating and maintenance instructions, refer to TM 3-6665-225-12. When used with the M992A1, the
instructions that follow also apply.
When vehicle is parked, connect detector unit (1) to vehicle hook-ups (2) via telephone cable (3). Detector unit (1)
must then be operated by its own power supply.
During periods of continuous operation, detector units fluid reservoir and air filter must be changed every
12 hours. When operating less than 12 hours per day, reservoir and filter must be changed daily. See TM
3-6665-22512 for complete Instructions. Failure to do this will greatly reduce effectiveness of the system.
Detector unit may also be used inside cargo compartment during transit, but its effectiveness will be greatly reduced.
Power for detector unit operation will come from the vehicle electrical system. To operate detector unit using vehicle
power, connect electrical wiring harness (4) to detector, and turn vehicle MASTER switch to ON.
