MR SERIES
The MR Series Assemblies consist of a speaker element attached to a waterproof
bellows assembly. They may be panel mounted, and are suitable for outdoor use
or repeated submersion.
CB SERIES
The CB Series Transceiver offers high electro-acoustic efficiency to conserve power in
push-to-talk radio handsets and other battery operated equipment. The CB is available
with mounting pins to facilitate assembly to a PC board. Model CB-23817-000 is designed
to survive submersion in water.
