Listening For A Lifetime
Selecting fine audio equipment such as the unit you’ve just purchased is only the start of
your musical enjoyment. Now it’s time to consider how you can maximize the fun and
excitement your equipment offers. VocoPro and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most out of your equipment by playing it at
a safe level. One that lets the sound come through loud and clear without annoying blaring
or distortion and, most importantly, without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing “comfort level” adapts to a higher volume of
sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard
against this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and clearly, and without
distortion.
Once you have established a comfortable sound level:
• Set the dial and leave it there.
• Pay attention to the different levels in various recordings.
Taking a minute to do this now will help to prevent hearing damage or loss in the future.
After all, we want you listening for a lifetime.
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since
hearing damage from loud noise is often undetectable until it is too late, this manufacturer
and the Electronic Industries Association’s Consumer Electronics Group recommend you
avoid prolonged exposure to excessive noise. This list of sound levels is included for your
protection.
Some common decibel ranges:
Level
30
40
50
60
70
80
Example
Quiet library, Soft whispers
Living room, Refrigerator, Bedroom away from traffic
Light traffic, Normal Conversation
Air Conditioner at 20 ft., Sewing machine
Vacuum cleaner, Hair dryer, Noisy Restaurant
Average city traffic, Garbage disposals, Alarm clock at 2 ft.
The following noises can be dangerous under constant exposure:
Level
90
100
120
140
180
Example
Subway, Motorcycle, Truck traffic, Lawn Mower
Garbage truck, Chainsaw, Pneumatics drill
Rock band concert in front of speakers
Gunshot blast, Jet plane
Rocket launching pad

FCC INFORMATION (U.S.A.)
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 instruc-
tions. 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 Regula-
tions, Part 15 for Class "B" digital devices. Compli-
ance 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 equip-
ment generates/uses radio frequencies and, if not
installed and used according to the instructions found
in the owner's manual, may cause interference harm-
ful to the operation of other electronic devices. Com-
pliance 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 satisfac-
tory results, please contact your local retailer autho-
rized 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, mois-
ture 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 discon-
nect 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 electric-
ity 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 insure
that the apparatus is indeed fully void if residual
power, leave unit disconnected from the AC outlet for at
least fifteen seconds.
CAUTION:
READ THIS BEFORE OPERATING YOUR UNIT
