F1 - POWER/ERROR Indicator
Lights when the unit is connected to the
required source of DC power via the rear panel
DC INPUT connector. A flashing condition
indicates an invalid channel setting or other
conditions that would cause the unit to operate
on an invalid channel. The RF output is
switched off for flashing (ERROR) conditions.
F2 - SIGNAL Indicator
Lights when a signal is present.
F3 - Channel Number Switch
Sets the desired operating channel for standard
CATV channels 02 through 135 or Broadcast
TV channels 02 through 69. See also Item F4
which sets the type of channel (CATV or
Broadcast TV) and sets the leading “1” for
CATV channels 100 through 135.
