RF Transmit Mode Switch
Allows the operator to select three different types of transmitting modes; continuous transmit, transmitter off, or remote transmitter. For most operations, place the transmitter switch in the “CONT” position (Continuous mode).
In the Continuous mode the RF transmitter will be on at all times regardless of whether the portables are on or not.
In the Remote mode, the only time the base can transmit is when a portable unit is turned on.
In the Off mode the base station will not transmit to the remote
