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.
 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.
 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

 To ensure the finest performance, please read this
manual carefully. Keep it in a safe place for future reference.
 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.
 Do not operate the unit upside-down.
 Never open the cabinet. If a foreign object drops into the
set, contact your dealer.
 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.
 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.
 Do not attempt to clean the unit with chemical solvents:
this might damage the finish. Use a clean, dry cloth.
 Be sure to read the "Troubleshooting" section on common
operating errors before concluding that your unit is faulty.
 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.
 To prevent lightning damage, pull out the power cord
and remove the antenna cable during an electrical storm.
 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.
