INSTRUCTION MANUAL

MEGAPHONES ER-520

ER-520S
ER-520W

Thank you for purchasing TOA's Megaphones.
Please carefully follow the instructions in this manual to ensure
long, trouble-free use of your equipment.

1. SAFETY PRECAUTIONS

2. GENERAL DESCRIPTION

Easy-to-operate 6 W handheld megaphones.
The ER-520S offers a siren switch, and the ER-520W is
equipped with a whistle switch.
The megaphones have a convenient carrying strap.
Handle and mouthpiece with anti-bacteria treatment improve
hygiene and safety during use.

3. HANDLING PRECAUTIONS

• The ER-520/520S/520W megaphones are not waterproof.
Avoid exposure to rain or environments where they may be
splashed by water or other liquids.

• Immediately contact your TOA dealer if the following
irregularities should occur. To avoid unit failure, make no
further attempt to use the unit in these conditions.

· Smoke coming from the unit or a strange smell detected.

· Water or other foreign objects get inside the unit.

· No sound heard (after checking to be sure that the batteries

are loaded in correct orientation, and satisfactorily charged).

• Avoid storing the unit in humid or dusty locations, in locations
exposed to direct sunlight, near heaters, or exposed to sooty
smoke, as these conditions may result in unit failure.

• When batteries are left installed in the megaphone for extended
periods of time, be sure to check them periodically for charge
and leakage.

• Do not use the unit for extended periods of time with a distorted
sound output. This could cause the inner parts to become hot
and possibly result in unit failure.

• Noise may be produced when a mobile phone is used near the
unit. However, this is not a failure. Use the mobile phone as far
as possible from the unit.

• Use a tightly wrung-out damp cloth to clean the unit. If the unit
becomes extremely dirty, use a cloth moistened in a neutral
detergent and tightly wrung-out. Never use volatile liquids such
as benzene, thinner, or alcohol to clean the unit, as these may
deform or discolor its case.

4. SPECIFICATIONS

*1Battery life estimates assume 30 minutes of continuous use

per day.

*

2

Audible range estimates assume use on a relatively quiet
street using new batteries and will vary depending on
remaining battery capacity, surrounding noise, wind direction,
obstacles and other environmental conditions.

Notes

• No accessory batteries are supplied.

• The design and specifications are subject to change without

notice for improvement.

CAUTION

Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.

• Cautions on Use
Be sure to observe the following instructions. Failing to
observe may cause hearing impairment.

· Reduce the volume to its lowest setting before use.

· Never use the megaphone in close proximity to a

person's ear.

· Point the megaphone toward the ground when

conducting operational tests.

• Make sure to observe the following handling precautions
so that a fire or personal injury does not result from
leakage or explosion of the battery.

· Do not short, disassemble, heat nor put the battery into

a fire.

· Avoid using both new and old batteries together.

· Never charge batteries of the type which are not

rechargeable.

· Do not solder a battery directly.

· Be sure to use the specified type of batteries.

· Note correct polarity (positive and negative orientation)

when inserting a battery in the unit.

· Avoid locations exposed to the direct sunlight, high

temperature and high humidity when storing batteries.

Step 2. Insert eight AA batteries referring to the polarity diagram

on the inside of the battery cover.

Step 3. Press the battery cover down and slide it in the direction

of the arrow until it clicks to lock.

6. REPLACING THE BATTERIES

Step 1. Using the volume control, adjust the volume to an

appropriate level that does not generate feedback when
holding down the talk switch.

Howling is more likely to occur when using the
megaphone indoors or in other reverberant places.
Particularly when the batteries are new, it may be
impossible to adjust the volume to maximum without
causing howling. In such cases, set the volume to about
mid-level.

Step 2. Speak into the mouthpiece at a distance of about 1 cm.

Note

Speaking too far from the mouthpiece or in too soft
voice may result in insufficient volume.

7. HOW TO USE

5. NOMENCLATURE AND FUNCTIONS

2. Talk switch

3. Strap

4. Mouthpiece

Speak into the mouthpiece at a distance of about 1 cm.
Anti-bacteria treated, the mouthpiece helps make such close
contact during use hygienic and safe.
