• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.

• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.

• Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as doing so may result in fire or electric shock.

•

Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and/or property damage.

• Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.

· If you detect smoke or a strange smell coming

from the unit.

· If water or any metallic object gets into the unit

· If the unit falls, or the unit case breaks

· If the power supply cord is damaged (exposure of

the core, disconnection, etc.)

· If it is malfunctioning (no tone sounds.)

• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.

• Do not touch the power supply plug during thunder and lightning, as this may result in electric shock.

• Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.

• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.

• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.

• Make sure that the volume control is set to minimum position before power is switched on. Loud noise produced at high volume when power is switched on can impair hearing.

• Do not operate the unit for an extended period of time with the sound distorting. This is an indication of a malfunction, which in turn can cause heat to generate and result in a fire.

• Use the AC adapter AD-246 (optional) or its equivalent. As for the usable adapter, consult your TOA dealer. Note that the use of an adapter other than specified may cause a fire.

• If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. Clean it periodically. In addition, insert the plug in the wall outlet securely.

• Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes when cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a fire or electric shock.

CAUTION

2. GENERAL DESCRIPTION

The EV-20R Sound Repeater is used to record and play back sounds produced from a microphone, CD player or other sources. Its particularly ideal applications include repeated broadcasts of the same message in schools, department stores and factories. Flash memory is used as a recording medium, and up to 4 different messages can be recorded and played back. The Sound Repeater also permits broadcasts to be made directly from the microphone or CD player without recording.

3. FEATURES

• A USB interface permits audio data to be transferred from a PC.

• Up to 4 messages can be recorded and played back.

• The maximum total recording time for the 4 messages is 6 minutes.

• Recorded data is not compressed, ensuring high quality sound output.

• A built-in power amplifier enables broadcasts with the simple connection of a speaker.

• Analog recording terminals enable direct recording from a microphone or CD player.

• Playback and stop functions can be remotely controlled by way of connected external equipment.

• Repeated broadcasts can be made.

4. HANDLING PRECAUTIONS

• Warning: This is a class A products. In a domestic environment this product may cause radio interference

in which case the user may be required to take adequate measures.

• Note: This equipment has been tested and found to comply with the limits for a Class A digital device,

pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

• To avoid radio interference, keep the unit and the optional AC adapter as far away as possible from radios or wireless tuners.

• Do not open the case nor perform any modifications to the unit, as this may result in unit failure. Leave the inspection, adjustment and repair of the unit's internal circuitry to your TOA dealer.

• The CD-ROM supplied with the unit is not for audio applications, and should not be used in an ordinary audio CD player.

• Internal Copyright Acts prohibit the copy or use of commercially available music and sound data for commercial purposes without the approval of the copyright holder. It is strongly advised that a copyright lawyer be consulted when using such material.

• When cleaning the unit, be sure to switch off the unit's power first, then wipe with a dry cloth. Should the unit become very dirty, use a cloth dampened in a neutral detergent. Never use benzene, thinner or chemicallytreated towels, as the unit's finish may be damaged.

• CD-ROM's sample audio data can only be used with the EV-20R, PM-20EV, EV-20A, EV-20S, and S-20S. Never use the data with other products. When wishing to use them with other products than specified, contact your TOA dealer.

5. PRE-RECORDED AUDIO DATA

The following 4 audio sources are pre-recorded in the unit when shipped from the factory.

* These audio sources are also contained in the supplied CD-ROM as sample audio data. Note: The above audio sources can be overwritten by using the supplied software.
