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.
