All external power sources are accessed through a common connector. A unique cable is provided to accommodate each
source. Two toggle switches operate as described in Table 4-2.
The power supply also incorporates an RF peak detector which produces a DC voltage that is proportional to the
transmitted RF power. The detector is used with the repeater unit as part of the RF output power automatic level control
(ALC).
