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.
Notes
• Speaking too far from the mouthpiece or in too soft
voice may result in insufficient volume.
• Moisture droplets collecting in the hole on the
mouthpiece may cause noticeably insufficient volume.
Wipe the droplets away with a cloth or other material
and allow the area to dry sufficiently before resuming
use.
[For ER-1215S]
When using the siren, pressing the talk switch will cause the
siren to stop sounding so that the voice announcement can be
heard. Releasing the talk switch allows the siren to resume.
