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

instructions contained in this manual, meets FCC 

requirements. Modifications not expressly approved by 

Vocopro may void your authority, granted by the FCC, 

to use this product.

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. Failure to follow instructions could void your 

FCC authorization to use this product in the U.S.A.

3. NOTE: This product has been tested and found to 

comply with the requirements listed in FCC Regulations, 

Part 15 for Class "B" digital devices. Compliance with 

these requirements provides a reasonable level of 

assurances that your use of this product in a residential 

environment will not result in harmful interference with 

other electronic devices. 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. Compliance with 

FCC regulations does not guarantee that interference 

will not occur in all installations. 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.

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.

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,  

    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.

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.

NOTE:

Please check the copyright laws in your country 

before recording from records, compact discs, 

radio, etc. Recording of copyrighted material may 

infringe copyright laws.

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 ensure 

that the apparatus is indeed fully void of residual power, 

leave unit disconnected from the AC outlet for at least 

fifteen seconds. 

CAUTION: 
READ THIS BEFORE OPERATING YOUR UNIT

Voltage Selector (General Model Only)

Be sure to position the voltage selector to match the
