TABLE OF CONTENTS

• 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.

2. GENERAL DESCRIPTION
The PM-20EV Sound Repeater is a paging microphone specially designed to record and play back the
broadcast contents.
It features a Rehearsal function that permits recorded message contents to be monitored before broadcast,
ensuring exacting announcement quality. Announcements can also be made directly from the PM-20EV's
built-in microphone, without requiring playback of prerecorded messages.
3. FEATURES
• Rehearsal function helps relieve tension and ensure accuracy during broadcasts.
• Built-in speaker permits recorded messages to be monitored before broadcast.
• Messages of up to 6 minutes in length can be recorded and played back with simple operation.
• Recorded data is not compressed, ensuring high quality sound output.
• A chime tone can be sounded before and after broadcasts.
• Internal chime data can be changed or messages recorded by connecting the unit to a personal computer
(PC) using the supplied USB cable.
• Built-in compression circuitry prevents sound output distortion caused by excessive signal input.
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.
