MAINTENANCE:
Remove dust and dirt wvlh a damp soft cloth. Heavier dirt should be removed with a damp soft cloth and mild detergent.
Do not use strong cleaning agents containing gasoline, thinner, benzene or alcohol. These substances may damage the
exterior surface of the monitor.
**CAUTION**
1. Before drilling, be sure no cable or wiring Is on the other side. Be sure to drill a IBrnm 15/B”) diameter hole only
2. Feed as much cable as possible into vehicle and clamp securely. This reduces the possibility of being hooked
during production.
3. Keep all cables away from HOT, ROTATING and ELECTRICALLY NOISY components.
4. To increase protection of cable, place all excess wire and extension cable in convoluted tubing.
5. Do not twist camera cable and do not cut camera pigtail or cable.
