IMPORTANT SAFETY INSTRUCTIONS

WARNING:

When using electric products, basic cautions should always be followed, including the following.

1.

Read all safety and operating instructions before using this product

2.

All safety and operating instructions should be retained for future reference

3.

Obey all cautions in the Operating instructions and on the back of the unit

4.

All operating instructions should be followed

5.

This product should not be used near water, i.e. a bathtub, sink, swimming pool, wet basement, etc.

6.

This product should be located so that its position does not interfere with its proper ventilation. It should not

be placed flat against a wall or placed in a built up enclosure that will impede the flow of cooling air.

7.

This product should not be placed near a source of heat such as stove, radiator, or another heat producing

amplifier.

8.

Connect only to a power supply of the type marked on the unit adjacent to the power supply cord.

9.

Never break off the ground pin on a power supply cord.

10.

Power supply cords should always be handled carefully. Never walk or place equipment on power supply

cords. Periodically check cords for cuts or signs of stress, especially at the plug and the point where the

chord exits the unit.

11.

The power supply cord should be unplugged when the unit is to be unused for long periods of time.

12.

If this product is to be mounted in an equipment rack, rear support should be provided.

13.

Metal parts can be cleaned with a damp cloth. The vinyl covering used on some units can be cleaned with

a damp cloth or ammonia based household cleaner if necessary. Disconnect the unit from the power

supply before cleaning.

14.

Care should be taken so that objects do not fall and liquids are not spilled into the unit through any

ventilation holes or openings.

15.

A qualified service technician should check the unit if:

The power cord has been damaged

Anything has fallen or spilled into the unit

The unit does not appear to operate correctly

The unit has been dropped or the enclosure damaged.

16.

The user should not attempt to service the equipment. All service work is done by a qualified

service technician.

17.

Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary

considerably in susceptibility to noise induced hearing loss, but nearly everyone will lose some hearing if

exposed to sufficiently intense noise for a sufficient time. The U.S. Government's Occupational Safety and

Health Administration (OSHA) has specified the following permissible noise level exposure.

According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear

plugs or protectors in the ear canals or over the ears must be worn when operating this amplification system in

order to prevent a permanent hearing loss if exposure exceeds the limits set forth above. To ensure against

potentially dangerous exposure to high sound pressure levels it is recommended that all persons exposed to

equipment capable of producing high sound pressure levels such as this amplification system be protected by

hearing protectors while this unit is in operation.
