second part is where it is located with a broadcast WRU ReFLEX message and the third part
where the pager is targeted with an AM voice message. The color code, which is stored in the
RF-B! transmitter controller, defines the transmitter from which the pager received the WRU
message. The AM voice message is targeted to a specific transmitter based on the received
color code.
Out of Range Indication on Nearby Pager
Check for the “out of range” symbol on the pager’s LCD screen. The “out of range” symbol
can be caused by incorrect modulation parameters on any nearby transmitter. A transmitter
with incorrect timing or phase can interfere with other simulcasting transmitters in the area.
Another cause is that the pager is programmed to the incorrect frequency.
Check the following FM modulation parameters.
RFA FIPS: r 2053
RFA FIPS: RR 2053 4800
(maximum FLEX™ deviation is 4800 Hz)
RFA FIPS: r 991
RFA FIPS:RR 991 1
(spectrum invert - default is Inverted (1))
If they are incorrect, this station is jamming the local simulcast data broadcasts. Make sure that
this station is not jamming due to poor simulcast synchronization. Check the error log (a 104)
for E_1PPS_INITIAL_SEARCH_FAILURE. Check the following RF-O! transmitter parameters:
Pager Registration at the WMG
Figure 6-5 shows the registration process. The home index (gateway) of the pager must match
the WMG home ID. The RF-A! receiver trace can be used to observe the registration request. A
registration can be forced by turning the pager on and off.
RFO FIPS: r 902
RFO FIPS: RR 902 5 (1PPS search window size)
RFO FIPS: r 2049
RFO FIPS: RR 2049 0 (simulcast launch delay)
RFO FIPS: r 2050
RFO FIPS: RR 2050 0 (simulcast frequency offset)
