7. USING THE SUPPLIED MICROPHONE
Step 1. Detach the microphone from the microphone hanger.
Step 2. Using the volume control, adjust the volume to an
appropriate level that does not generate feedback when
holding down the talk switch.
Feedback is more likely to occur when using the
megaphone indoors or in other reverberant places.
Particularly when the batteries are new, it may be
impossible to adjust the volume to maximum without
causing howling. In such cases, set the volume to about
mid-level.
Step 3. Speak into the microphone while holding it about 1 cm
away from the mouth.
Note: Speaking too far from the microphone or in too
soft voice may result in insufficient volume.
[When Attaching the Microphone]
Reduce the volume to its lowest setting, then press the
microphone onto the hanger. Leaving the volume set higher can
cause howling if the talk switch is accidentally pressed when
attaching or detaching the microphone.
Step 1. Remove the tuner cover located above the battery
cover. To do this, remove both the left and right cover
mounting screws.
Step 2. Insert the optional WTU-3800/4800 Wireless Tuner
Module into the tuner receptacle.
Notes
• Avoid using any other than the designated type of
tuner module. The megaphone could be damaged.
• Ensure that the group/channel numbers of the tuner
module match those of the wireless microphone.
• Take care regarding the correct orientation of the tuner
module and fully insert the module into the tuner
receptacle.
Step 3. Replace the tuner cover.

conducting operational tests.
CAUTION

operational tests.
Notes

interference, change the tuner module's group/channel number.
Note that changing the number unnecessarily could adversely
affect the tuner module's reception.
• When changing the group/channel number, also change that of
the wireless microphone to the same number as the tuner
module's.
Step 1. Open the rubber cover on the tuner cover.

screwdriver supplied with the tuner module.
