MAINTENANCE INFORMATION
General
In general the OMD is practically maintenance free. Normally,
the only maintenance required is to clean the lenses periodi-
cally with a wet cotton rag. It is recommended, however,
during winter conditions when sand and salt are used on the
roadways that the light bar/receiver assembly is rinsed with
water daily to prevent buildup of mineral deposits.
Recommended Spare Parts
There are only two recommended spare parts for the OMD.
The first is the IR specific halogen lamp, which is rated to last
one to two years. The Heath part number for the lamp is
2510592. The second is a fuse: 7 amp SLO-BLO (3AG), Heath
part number 2510569.
