Analog Wireless Intercom System
The wireless intercom system of Tamura is a contact/connection system in which an
operator can exchange information and issue an emergency order freely and without fail
by radio communication from a work site at any time.
Because the system employs an antenna dispersed system, it is possible to eliminate a
non-sensitive zone of radio waves even in a hidden service area by comprising a system
with its smallest inuence.
