3.2 Power Switches

3.2.1 Power Switch

The main on/off power switch controls both the 120/240 VAC and the DC battery power in-
put.

3.2.2 Carrier Switch

This switch controls power to the RF amplifiers and supplies a logic high to the voltage
regulator board, which enables the supply for the RF driver. In addition, the Carrier Switch
controls the operating voltage needed by the switching power regulator.
A "Lock Fault" or a low pin 17 (/Carrier Off) on the Remote I/O connector will hold the carrier
off. (See section 2.12.)
