Operation
Operational Description
The IDR1000A DC Remote Desk Set provides radio system control from a remote location. Changes in
dc current through a telephone line tell the remote adapter to control radio functions such as transmit,
channel changes, and monitor. Receive audio from the system radio system is sent to the IDR1000A
from the radio via the same telephone line connection. The IDR1000A must be connected to a dc remote
adapter, such as an IDA1000, located at the radio site.
