STEP 12
Examine Figure G-2 on page G-6 and compare the jumper locations
shown there with your monitor board jumpers. Change the monitor
board jumpers to match the settings shown.
STEP 13
Install 6 dB attenuators in the sample lines of the Visual Reflected and
Aural Reflected couplers at the output of the transmitter.
NOTE:
Early transmitters equipped with saddle couplers were configured with 6 dB
greater sensitivity in reflected directional couplers than in the forward couplers.
Monitor firmware revision E.0.12 and earlier was designed to accept this
difference. Current transmitter firmware does not require this 6 dB difference and
will display 6 dB higher reflected power levels if the 6 dB attenuators are not
installed.
STEP 14
When you are satisfied the new IC's are properly installed, turn ON the
control cabinet circuit breaker and observe the front panel display. The
transmitter should come on in the normal manner and after a short delay
the usual output power bargraph User Display should appear.
STEP 15
If the monitor board does not appear to be starting up properly, press the
small blue RESET button at the top left edge of the board to ensure all
memory is cleared.
STEP 16
If the monitor board still will not start properly, turn off the circuit
breaker and recheck all the installed IC's for a possible misaligned pin.
Check to be certain all jumpers are set as shown in Figure G-2.
STEP 17
Connect the battery to the monitor board terminals.
STEP 18
Using the SETUP screens, set the clock/calendar day and date.
STEP 19
Enter any other special data or entries needed for your transmitter
operation and check all screens for normal displays and data.
STEP 20
You should find a new SENTRY™ setup screen by selecting [Setup],
