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.

2. GENERAL DESCRIPTION

Shoulder-held 15 W megaphones with a removable microphone.
In addition, the ER-2215W is equipped with a whistle switch.
The megaphones can be mounted on the optionally available
ST-16 Speaker Stand.
Microphone with anti-bacteria treatment improve hygiene and
safety during use.

3. HANDLING PRECAUTIONS

• The ER-2215/2215W 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.

5. NOMENCLATURE AND FUNCTIONS

Step 1. Rotate the battery cover counterclockwise to remove it.

Step 2. Insert six C batteries referring to the polarity diagram on

the inside of the battery compartment.

Step 3. Insert the tab on the inside of the battery cover into the

slot in the battery compartment as shown and turn the
battery cover clockwise until tight.

6. REPLACING THE BATTERIES

1. Speaker (outer horn)

2. Shoulder strap

Use this strap to hang the
unit from the shoulder for
transport or use.
(Length: approx. 1 m)

3. Microphone hanger

Hook the microphone onto
this hanger when not using
it.

4. Signal tone switch

(ER-2215W only)

A whistle tone sounds while
this switch is pressed, and
stops when released.

Note

Output volume is fixed, and
cannot be adjusted with the
volume control.

5. Battery Cover

The battery compartment is
built inside.
When replacing the batteries,
turn counterclockwise to open
the cover, and clockwise to
close it.

6. Stand socket

The megaphone can be
mounted on the optionally
available ST-16 Speaker
Stand using the threaded
hole on its bottom.
For mounting details, refer
to the ST-16 instruction
manual.

7. Talk switch

Press to talk (power turns
ON). Release to turn the
power OFF.

8. Volume control

Rotate upward to increase
output volume.

Step 1. Detach the microphone from the microphone hanger.

Step 2. 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 3. Speak into the microphone while holding it about 1 cm

away from the mouth.

Note

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

[When Attaching the Microphone]

Reduce the volume to its lowest setting, then press the
microphone onto the hanger. Leaving the volume set higher can
cause howling if the talk switch is accidentally pressed when
attaching or removing the microphone.

7. HOW TO USE

CAUTION

• Before pressing the microphone's talk switch, fully turn
down the volume.

• Point the megaphone toward the ground when conducting
operational tests.
