Your hearing and the hearing of others,
close to the electronic megaphone, could be
damaged by loud sounds. This can occur from
short exposures to very loud sounds, or from
longer exposures to moderately loud sounds.
For hearing conservation guidance, refer to
federal, state, or local recommendations.
OSHA Standard 1910.95 offers guidance on
"Permissible Noise Exposure."
3-1. CLEANING.
Molded parts of the Voice Gun electronic
megaphone are made of exceptionally tough and rugged
material. When cleaning molded parts, use a damp cloth
and mild detergent. Do Not use solvent or strong cleaning
agents.
3-2. BATTERY REPLACEMENT.
Power is supplied by eight inexpensive penlight type
flashlight cells size AA. At least 1500 to 3000 ten-second
messages should be expected from one set of batteries.
For many users, battery life will approach shelf life. It is
recommended that batteries be replaced yearly, even
though still functioning. For longer shelf life and much
longer operating life, we recommend use of alkaline
batteries equal to the following:
1. Eveready No. E91
2. Mallory Duracell No.MN1500
3. Burgess No. AL9
To remove batteries, proceed as follows:
A. Apply slight pressure with thumb against
battery cartridge at bottom of handle.
B. Remove locking thumb screw. If tight, screw
may be started with a thin coin.
C. Remove cartridge.
D. All batteries should be placed in position with
the small battery tip pointing away from the springs at the
top and bottom of the cartridge (see figure 1).
3-3. FACTORY SERVICE.
Should the electronic megaphone not function, or
not function properly after proper installation of good
batteries, it is suggested that the factory be contacted.
Describe briefly what the difficulty seems to be.
