6.4.4 TUNING FORK TEST FAILURE
If the proper speed readings are not obtained during the
previous tests, check the following:
1. The Raptor RP-1 cannot test tuning forks if the system
is not in Test mode as indicated by the FORK TEST
displayed in the message area.
2. Verify that the tuning forks are the proper tuning forks
supplied with the unit.
3. Striking the tuning fork too hard or on a metallic
surface will cause spurious overtones from the tuning
fork. This may cause the speed readings to be double
the specified speed. Also, moving the tuning fork while
in front of the antenna may cause the speed reading to
be slightly lower or higher than specified. These
readings are only momentary and the proper readings
should appear as the false overtones dissipate.
NOTE: Do not move the tuning forks after they have been
placed in front of the antenna.
4. Ensure that the Raptor RP-1 is in the transmit mode and
the range control is set to maximum.
5. If the proper readings cannot be obtained, remove the
unit from service and contact Kustom Signals Service
Support. 1-800-835-0156 (620-431-2700)
