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.
