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

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

Example

100

120

140

180

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.)

CAUTION:

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.

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, mois-

ture or cold. Avoid sources of hum (transformers, v

motors). To prevent fire or electrical shock, do not expose

to rain and water.

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. Do not operate the unit upside-down.

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:

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.

Relocate either this product or the device that is

being affected by the interference.

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.

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.

10. To prevent lightning damage, pull out the power cord

and remove the antenna cable during an electrical storm.

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.

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.

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.

NOTE:

Please check the copyright laws in your country

before recording from records, compact discs, radio,

etc. Recording of copyrighted material may infringe
