5. NOMENCLATURE AND FUNCTIONS

ER-2215S-AS
ER-3215S-AS

2. GENERAL DESCRIPTION

ER-2215S-AS and ER-3215S-AS is a 15W megaphone with
removable microphone. Microphone and handle with anti-bacteria
treatment improve hygiene and safety during use.

3. HANDLING PRECAUTION

• The megaphone is not waterproof. Avoid exposure to rain or
environment where it may be splashed by water or liquids.

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

*1 Battery 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.

• Water or other foreign objects get inside the unit.

• No sound heard (after checking to be sure that batteries are

loaded in correct orientation and satisfactorily charged).

• 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 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 or alcohol to clean, as these may deform its case.

Note (only ER-3215S-AS)

turns the power on for use.

7. HOW TO USE

Step 1 Detach the microphone from the microphone hanger.
Note

Use the talk switch on the handle to activate the

megaphone for use, even when the microphone is
attached to the hanger. For ER-3215S-AS, the hanger
can rotate 360° to allow easy microphone positioning.

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.

6. REPLACING THE BATTERIES

Step 1 Rotate the battery cover counterclockwise to remove it.

Note
Detach the microphone from the hanger in advance.

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.
