SAFETY INFORMATION (U.S.A.)

CAUTION:

1. IMPORTANT NOTICE: DO NOT MODIFY THIS
UNIT!: This product, when installed as indicated in the

instructions contained in this manual, meets Q.C.
requirements. Modifications not expressly approved by
Vocopro may void your warrenty.

2. IMPORTANT: When connecting this product to
accessories and/or another product use only high
quality shielded cables. Cable(s) supplied with this
product MUST be used. Follow all installation
instructions.

3. NOTE: This equipment generates/uses radio
frequencies and, if not installed and used according to
the instructions found in the owner's manual, may cause
interference harmful to the operation of other electronic
devices. If this product is found to be the source of
interference, which can be determined by turning the
unit "Off" and "On", please try to eliminate the problem
by using one of the following measures:

Relocate either this product or the device that is being
affected by the interference.

Use power outlets that are on different branch (circuit
breaker or fuse) circuits or install AC line filter(s).

In the case of radio or TV interference, relocate/reorient
the antenna. If the antenna lead-in is 300-ohm ribbon
lead, change the lead-in to coaxial type cable.

READ THIS BEFORE OPERATING YOUR UNIT

1. To ensure the finest performance, please read this

manual carefully. Keep it in a safe place for future reference.

2. Install your unit in a cool, dry, clean place - away from
windows, heat sources, and too much vibration, dust,
moisture or cold. Avoid sources of hum (transformers, v
motors). To prevent fire or electrical shock, do not expose to
rain and water.

3. Do not operate the unit upside-down.

4. Never open the cabinet. If a foreign object drops into the

set, contact your dealer.

5. Place the unit in a location with adequate air circulation.
Do not interfere with its proper ventilation; this will cause the
internal temperature to rise and may result in a failure.

6. Do not use force on switches, knobs or cords. When
moving the unit, first turn the unit off. Then gently disconnect
the power plug and the cords connecting to other
equipment. Never pull the cord itself.

7. Do not attempt to clean the unit with chemical solvents:
this might damage the finish. Use a clean, dry cloth.

8. Be sure to read the "Troubleshooting" section on common
operating errors before concluding that your unit is faulty.

If these corrective measures do not produce satisfactory
results, please contact your local retailer authorized to
distribute Vocopro products. If you can not locate the
appropriate retailer, please contact Vocopro, 1728
Curtiss Court, La Verne, CA 91750.

CAUTION

The apparatus is not disconnected from the AC power
source so long as it is connected to the wall outlet,
even if the apparatus itself is turned off. To fully insure
that the apparatus is indeed fully void if residual power,
leave unit disconnected from the AC outlet for at least
fifteen seconds.

9. This unit consumes a fair amount of power even when the
power switch is turned off. We recommend that you unplug
the power cord from the wall outlet if the unit is not going to
be used for a long time. This will save electricity and help
prevent fire hazards. To disconnect the cord, pull it out by
grasping the plug. Never pull the cord itself.

10. To prevent lightning damage, pull out the power cord
and remove the antenna cable during an electrical storm.

11. The general digital signals may interfere with other
equipment such as tuners or receivers. Move the system
farther away from such equipment if interference is

observed.
