Step 1. Connect the external equipment.
1-1. When using a general-purpose microphone
Connect the moving coil-type microphone to the
External microphone input terminal.
1-2. When using a CD, MD or cassette player
Connect the CD, MD or cassette player to the Auxiliary
input terminal using the supplied 3.5 mm mono plug.
Note
Arrange for the connection cord and external equipment
connection plug separately. It is recommended that the
commercial 3.5 mm stereo plug for audio applications
be used.
Step 2. Turn ON the External input power switch on the
operation panel.
The power indicator lights.
Note
If the indicator flashes, this indicates that the batteries
need replacement.
Step 3. Adjust the volume.
Use the External microphone volume control or the Aux
input volume control corresponding to the input in use.
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.
Step 4. After use, fully turn down the volume control and be sure
to set the External input power switch to the OFF position.
Note
While the power switch is turned ON, electrical current
continues to flow to the electrical circuit, resulting in
quickly drained batteries.
10. USING THE EXTERNAL POWER SUPPLY
Make the white character side positive (+).
To External power input terminal
External power plug cord
(supplied)
Using the supplied plug cord for external power, connect a 12 V
battery to the External power input terminal on the operation
panel. Connect the white character side of the external power
cord to the positive (+) terminal.

Notes
• Inserting the plug into the External power input terminal
disconnects the internal power (dry battery), permitting the
external power supply to take precedence.
• When connecting to a 12 V battery, be sure to insert a 5 A fuse
(separately available) for safety.
• Do not power the megaphone from a vehicle cigarette lighter
socket while the engine is running. The battery voltage may rise,
possibly causing unit failure.
