Note : If no RF power is achieved, check the DPM display for a flashing dot in the
lower right corner of the display. If this is present, the system needs to be reset
before power can be restored. Refer to illustration 2-15, section 2.5, Remote I/O
connections pin 3 of Port A for further information.
9. Using the 'raise/lower RF power' buttons, raise or lower the RF power to the
desired setting (unless the power was specified at time of order).
10. Use the 'Fwd/Rev' selector switch to check for reflected power on antenna
feed-line if desired.
11. Use the PA1 through PA5 power controls to limit the amount of power output
the transmitter can achieve. The FM10000 is set to limit at 11000 watts in the
preset condition. For settings lower than this, adjust each PA control counter-
clockwise in small equal increments to the desired level. For a more secure
method, use the power set control located behind each front panel of each PA. The
settings on the individual PA's are unconventional in that a lowering of power is
achieved by adjusting the control clockwise.
The remainder of this section describes the controller and its functions.
3.2 AC Power Switch
The Transmitter Controller's AC power is controlled by a switch located on
the AC input filter. The AC input range is 100-250 VAC. The fuse type and
size are 3AGC at 1/2 amp slo-blo and there are 2 fuses. See illustration 3-2
for switch location.
