SAFETY PRECAUTIONS

WARNING: EYE PROTECTION SHOULD BE USEDWHEN SERVICING GLASS COMPONENTS. PER-

SONAL INJURY CAN RESULT.

CAUTION: Do not touch the glass of halogen bulbs

with fingers or other possibly oily surface, reducedbulb life will result.

Do not use bulbs with higher candle power thanindicated in the Bulb Application table at the end of

this group. Damage to lamp can result.Do not use fuses, circuit breakers or relays hav-

ing greater amperage value than indicated on thefuse panel or in the Owners Manual.

When i t is necessary to remove components to ser-
