INSTRUCTION MANUAL
1. SAFETY PRECAUTIONS
• Be sure to read the instructions in this section carefully before use.
• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages
regarded as very important precautions are included.
• We also recommend you keep this instruction manual handy for future reference.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
CAUTION
• Make sure that the volume control is set to minimum position before use. Loud noise produced when using
the unit at high volume can impair hearing.
• 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.
· Do not solder a battery directly.
· 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
TOA's ER-604W megaphone is a small, lightweight shoulder-held megaphone that is also supplied with a
whistle. Its close-talking microphone features a press-to-talk switch and a volume control, which can be easily
operated by hand. The ER-604W's External input terminals can also be connected to an optional wired
microphone, headset microphone, CD player, MD player or cassette player to make public address
announcements or play music.
3. HANDLING PRECAUTIONS
• The ER-604W megaphone is not waterproof. Avoid exposure to rain or environments where it may be
splashed by water or other liquids.
• When the batteries are left loaded for long periods of time, be sure to check the batteries periodically for
discharge and leakage.
• Immediately contact your TOA dealer if the following irregularities should occur.
· 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).
To avoid catastrophic failure, make no further attempt to use the unit in these conditions.
• 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.
• Do not use the unit for extended periods of time with a distorted sound output. This could cause the speaker
to become hot and possibly result in unit failure.
• Noise may be produced when a mobile phone is used in close proximity of 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 thinner
to clean the unit, as these may deform or discolor its case.

About the Voice switch (11) (normally set to the OFF position).
When using equipment connected to External input terminals (13) (15), battery discharge can be–
prevented by setting the Voice switch to the ON position, thus allowing the unit to be used for longer
periods of time. This is especially convenient when intermittently using an external microphone, since it
can be used freely with no need to constantly turn its power switch ON and OFF.
When the Voice switch is in the ON position, the unit automatically switches to operation mode at the
first detection of external input, and switches to Standby mode if no signal is received from the
connected external equipment for a period of 2 3 seconds.–
Notes
•Immediately after the Voice switch is turned ON, there may be a momentary loss of initial output,
however this is not a failure. If this is not acceptable, leave the switch OFF.
•The Voice switch function cannot be used with the attached hand-held microphone.
Battery cover
5. BATTERY INSTALLATION
Step 1. Remove the battery cover (16) by unscrewing its knob counterclockwise.
Step 2. Insert 8 batteries, noting the battery polarity markings provided inside the
receptacle.
Step 3. Correctly replace the cover, then secure with its screw knob slightly
holding the battery cover.
6. USING THE SUPPLIED MICROPHONE
Step 1. Detach the microphone from the microphone hanger (3).
Step 2. Using the volume control (5), adjust the volume to an appropriate level that does not generate
feedback when holding down the microphone talk switch (4).
Step 3. Speak into the microphone while holding it about 1 cm away from the mouth.
Notes
•Take care not to block the holes in the microphone's rear panel, as output volume could be
drastically reduced.
•The microphone features an anti-bacterial treatment which helps keep it clean and sanitary.
7. USING EXTERNAL EQUIPMENT
Step 1. Connect the external equipment.
1-1. When using a general-purpose microphone
Connect the moving coil-type microphone to the General microphone input terminal [MIC 1] (13).
1-2. When using a headset microphone
Connect the headset microphone to the Electret condenser microphone input terminal [MIC 2] (14).
Notes
•To avoid megaphone failures, do not connect any other equipment than an electret condenser
microphone to these inputs.
•When using TOA's optional WH-4000A Headset Microphone, speak into the microphone while
keeping it about 1 cm away from the mouth. Although the WH4000A Microphone has a lock knob for
securing the plug, this lock knob is not used with the ER-604W Megaphone.
1-3. When using a CD, MD or cassette player
Connect the CD, MD or cassette player to the Auxiliary input terminal [AUX] (15) using the supplied
3.5 mm mini plug.
Note: When using the supplied mini plug, the connection cord and external equipment-side plug must
be prepared separately.
Step 2. Set the External input power switch [POWER] (9) to the ON position.
Step 3. Adjust the volume with the External input volume control [VOLUME] (7).
Note: Connected external equipment can be used simultaneously. However, since the volume of
each component cannot be individually adjusted by the megaphone, use each component's
volume control for individual volume adjustment.
Notes on Microphone Storage
Set the volume control (5) to the minimum position, and insert the microphone into the microphone hanger (3).
If the microphone is inserted with the volume control set to the high volume position, when it is inserted into
or detached from the hanger, the talk switch (4) could be accidentally pressed, causing feedback.
