Step 2. Insert eight AA batteries referring to the polarity diagram
on the inside of the battery cover.
Step 3. Press the battery cover down and slide it in the direction
of the arrow until it clicks to lock.
6. REPLACING THE BATTERIES
Step 1. Using the volume control, adjust the volume to an
appropriate level that does not generate feedback when
holding down the talk switch.
Howling 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 2. Speak into the mouthpiece at a distance of about 1 cm.
Note
Speaking too far from the mouthpiece or in too soft
voice may result in insufficient volume.
