Important Safeguards and Precautions:

3

All Crate products are designed for continuous safe operation. Abiding by the following
rules can help prevent damage to your amplifier, yourself and others.

• The amplifier is equipped with a three-pronged AC power cord. To
reduce the risk of electrical shock, NEVER remove or otherwise attempt
to defeat the ground pin of the power cord.

• Connect the amplifier ONLY to a properly grounded AC outlet of the
proper voltage for your amp.

• Avoid sudden temperature extremes, rain and moisture. Also, avoid
sudden and intense impact. (If the unit has been subjected to any of the
preceding abuses, have it looked at by an authorized service center.)

• Do not expose the unit to splashing or dripping liquid. Do not place liq­uid filled objects on the unit.

• NEVER set the amplifier on a support that will not bear its weight.

• Always keep the total speaker impedance at or above the rated load.

• Unplug the amplifier before cleaning it. NEVER spray liquid cleaners

onto the amplifier. Wipe it with a slightly dampened, lint-free cloth to
remove dirt and film.

• DO NOT use the amplifier if it has sustained damage to the chassis,
controls, or power cord. Refer the unit to an authorized service center
for inspection.

• Prolonged exposure to high volume levels may cause permanent hear­ing loss or damage. Such damage is progressive and irreversible!
