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!
