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.

• 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.

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.

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.

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.

8. USING THE EXTERNAL POWER SUPPLY

Using the supplied plug cord for external power, connect a 12 V battery or AC adapter (12 V, over 0.8 A) to the External power input terminal [EXT. POWER] (12) on the rear panel. Connect the white character side of the external power cord to the positive (+) terminal.

Notes

• When connecting to a 12 V battery, be sure to insert a 2 A fuse (separately available) for safety.
• Do not power the megaphone from a vehicle cigarette lighter socket while the engine is running. Potential fluctuations in battery voltage could cause unit failure.
