Maintenance RF-Orchestra!™ Transmitter Installation and Operation

Check the 1PPS search window size (RFO FIPS: r 902). If the window size is not the
default value (5), erase the error log (RFO FIPS: a 111), set the window size to 5 (RFO
FIPS: w 902 5), then check the error log after 1 minute.
If the E_1PPS_INITIAL_SEARCH_FAILURE is in the error log again, you should also
check the RF-B! transmitter controller for the E_1PPS_INITIAL_SEARCH_FAILURE.
Power Cutback LED is Blinking
When the Power Cutback LED is blinking, this indicates that the RF-O! transmitter is disabled
(shutdown). When disabled the RF-O! transmitter will not key (even with test modes). Use
RFO FIPS: a 83 to determine why the transmitter is disabled. Check for any of the PAGING
DISABLE STATUS sources being ACTIVE. Also, use RFO FIPS: a 104 and a99to determine the
reason the transmitter is disabled.
If the RF-B! transmitter controller was recently reset, it is very likely that the External 1 PPS
signal has not been acquired (See a83example above). The External 1 PPS disable should clear
within 10 minutes, as long as the GPS receiver eventually locks.
RFO FIPS: a 83
RFO FIPS: RA 83
