know how to operate it property and effectively.
Precautions
Do not place under the direct sunlight or the high temperature environment for a long period of
time.
Avoid exposure to rain, water or heavy humidity.
When cleaning the megaphone body only use a neutral detergent. Never use thinner or benzene.
Amplified sound or howling may cause damage to person’s ears. Don’t use the megaphone close
to people’s ears.
If not in use for a long period of time, remove the batteries and store them separately to prevent
leaking batteries and damaging the circuits inside the megaphone.
When the megaphone is not in use, put the signal switch(2) in the “talk” position, and the Press-to-
talk switch(3) in a natural position in order to extend the use of the batteries. This is the battery
power saving procedure that will make the battery work longer for your megaphone.
