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 an audio player
Connect an audio player to the Auxiliary input terminal
using the supplied 3.5 mm mini 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.
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.
10. USING THE EXTERNAL POWER SUPPLY
Use a 5 A fuse (procured separately).
To External power input terminal
Make the white character side positive (+).
External power plug cord
(supplied)
The center terminal of the plug is positive.
11. SPECIFICATIONS

using new batteries and will vary depending on remaining battery
capacity, surrounding noise, wind direction, obstacles and other
environmental conditions.
* 3 0 dB = 1 V
* 4 Without batteries
Notes
• No accessory batteries are supplied.
