SPEAKER MICROPHONE

GENERAL

The Shure Model 810 is a shoulder-worn speaker micro-

phone designed for rugged and reliable operation in a vari-
ety of portable communication applications, including po-
lice, fire, utility, forestry, transportation, industrial, and
emergency medical. The 810 has an omnidirectional pickup
pattern and provides highly intelligible speech communica-
tion with its clear, crisp, natural voice response.

The 810 can be used with a variety of ALM cordsets to

connect to many popular two-way radios. The unit fits natu-
rally and comfortably in the hand and is not affected by heat
or humidity. The exclusive ARMO-DUR

case is immune to

oil, grease, fumes, salt spray, sun, rust and corrosion—and
is outstanding in its ability to withstand mechanical shocks
and vibration.
