(m) The GUI will indicate that the
transmitter is operating in preset 5. The
remote interface PWB’s Preset 5
Status pin (J4-19) shall be a current-
sink-to-ground.
(n) Remotely select preset 6 by activating
an input to remote interface PWB's Ext
Preset 6 pin(s) [J4-12 (+)/J4-13 (-)].
(o) The RF output, as displayed by the RF
KILOWATTS meter and GUI, will be
the preset 6 power level.
(p) The GUI will indicate that the
transmitter is operating in preset 6. The
remote interface PWB’s Preset 6
Status pin (J4-20) will be a current-
sink-to-ground.
(q) Remotely select preset 1 by activating
an input to remote interface PWB's Ext
Preset 1 pin(s) [J4-2 (+)/J4-3 (-)].
(r) The RF output, as displayed by the RF
KILOWATTS meter and GUI, will be
the preset 1 power level.
(s) The GUI will indicate that the
transmitter is operating in preset 1. The
remote interface PWB’s Preset 1
Status pin (J4-15) will be a current-
sink-to-ground.
4.3.5.8 Remote Power Trim Control
Verify the RF output power can be trimmed
from a remote location as follows:
(a) Verify 4.3.5.1 is complete.
(b) The RF output, as displayed by the RF
KILOWATTS meter and GUI, will be
rated power.
(c) Verify local RF power control has no
influence. Press/hold the Control -
Decrease switch. The RF output will
not change. Release the Control -
Decrease switch.
NOTE
To activate a remote power trim, hold the
input then release it. The output power
changes upon release of the trim input.
If the input is momentarily applied and
released, the output power changes in
smaller steps [in FM mode, increment is
100 W (V10/V7.5) or 50 W (V5/V3.5); in
FM+HD or HD mode, increment is 1% of
rated transmitter power (see 2.2.13.7)] until
reaching minimum or maximum power.
If the input is applied, held for more than
three seconds and released, the output
power changes in larger steps [in FM
mode, increment is 1000 W (V10/V7.5) or
500 W (V5/V3.5); in FM+HD or HD mode,
increment is 10% of rated transmitter
power (see 2.2.13.7)] until reaching
minimum or maximum power.
(d) Remotely decrease the RF output.
Repeatedly activate a remote Power
Decrease input to remote interface
PWB's EXT PWR DECR terminal(s)
[TB4-9 (+)/TB4-10 (-)].
(e) The RF output, as displayed by the RF
KILOWATTS meter and GUI, will
decrease to its minimum power level.
(f) Verify local RF power control has no
influence. Press/hold the Control -
Increase switch. The RF output will not
change. Release the Control -
Increase switch.
(g) Remotely increase the RF output.
Repeatedly activate a remote Power
Increase input to remote interface
PWB's EXT PWR INCR terminals(s)
[TB4-7 (+)/TB4-8 (-)].
(h) The RF output, as displayed by the RF
KILOWATTS meter and GUI, will
increase to its maximum power level.
(i) Remotely decrease the RF output to
rated power.
