3.0 OPERATION
3.1
A siren, incorporated into the megaphone, is automatically activated by
unplugging the alarm plug pin.*
Note:
A long lanyard with an alarm plug pin is supplied with the
megaphone for use as an anti-theft alarm (optional).
3.2
Squeezing the handle automatically stops the siren, and the megaphone is
ready for use. Re-insert the alarm pin so that alarm will not be reactivated
when pressure on the handle is removed.
3.3
Hold the megaphone in one hand. Place mouth almost in contact with the
microphone mouthpiece at the rear of the assembly. Squeeze the handle,
which will flex slightly, turning the megaphone “ON” and speak slowly
with loud, crisp, clear tones.
Megaphones without the optional gain control knob are preset to a
standard level via control under access hole plug.
