Moving Test - Kustom Signals HR-12 Operator's Manual

Moving Mode
1. Place the system in the Moving Mode by setting the MOV-STA switch to the MOV
position. Leave the RANGE control clockwise.
2. Lightly strike both tuning forks on a hard, non-metallic surface. Hold the 35 MPH
(45 KPH) tuning fork approximately one inch in front of the antenna until the
PATROL display registers "35" (45). Then place the second tuning fork
approximately one inch in front of the antenna (both forks should be in front of the
antenna at this time). The TARGET display should register "30" (35).
If the proper reading is not obtained:
1. Make sure that Kustom Signals K-Band tuning forks have been used ("K-Band" is
stamped plainly on each fork). X-Band tuning forks, or tuning forks designed for use
with other manufacturers' radar, will not give the proper readings.
2. Striking the tuning forks too hard may produce false overtones which may be read as
speeds slightly above or below those specified. These possible false readings are
momentary, and the proper readings should appear as the false overtones dissipate.
Do not move the tuning forks after placing in front of the antenna.
3. Ensure the system is not in the Hold Mode.
4. Extremely cold or extremely hot tuning forks may give readings slightly above or
below those specified, due to the effect of extreme temperature on the metal. If this is
the case, warm or cool the forks to normal room temperature before use.
NOTE: If correct readings are not obtained after Points 1-4 have been rechecked, the
system should be shut down and taken out of service.

MOVING TEST

For an additional check of the unit, aim the radar straight ahead, drive the patrol vehicle,
and compare the reading in the display with the vehicle's speedometer. The speed
registered in the display and speedometer should coincide, or be within reasonable limits
(allowing for minor speedometer error). These comparisons, on a day-by-day basis, are a
reliable way to check the accuracy of your radar. If there are major discrepancies
between the speed registered and the vehicle speedometer, the system should be taken out
of service until the discrepancies are resolved. (This check is one of the best ways to
verify the proper operation of your radar.)
