are 2300 frequencies available, most noise sources, including other brands of detectors, can
be eliminated with a setting between 50 and 400.
Note: This adjustment is most effective with M Filter OFF.
Note: If Line Sync is set to ON, Frequency adjustment has no effect on the detector.
3.5.35 Line Sync - This feature is used to place the detector into free-run operation, thereby
allowing adjustment of the operating Frequency. To place detector into free-run operation, set
Line Sync to OFF using the + or – touchpads. To place the unit into its normal line-sync'd
operation, set Line Sync to ON.
Note: Line Sync should normally be set to ON, especially when operating in proximity to
other Garrett walk-through metal detectors. Line Sync should only be set to OFF (i.e. free-
run operation) when operating with non-Garrett walk-through metal detectors or other types
of interference sources requiring elimination via Frequency adjustment.
Note: If Line Sync is set to OFF, Channel adjustment has no effect on the detector.
3.5.36 Transmit Configuration - This feature allows the transmitters in each panel to be
independently switched on or off. This feature may be useful when attempting to operate
within 20" (50 cm) of non-Garrett walk-through detectors (see illustrations in Section 2.3.4).
Specifically, if the RX panel of the non-Garrett detector is closest to the PD- 6500i , then it may
be necessary to turn OFF the PD- 6500i 's adjacent transmitter to prevent excessive
interference in the non-Garrett detector. If the TX panel of the non-Garrett detector is closest to
the PD- 6500i , then it may be necessary to turn OFF the PD- 6500i 's distant transmitter to
prevent overload of the PD- 6500i (indicated by warble audio). These are the only situations
where one of the PD- 6500i 's transmitters should be switched OFF. For all other situations,
both PD- 6500i transmitters should be switched ON. An LCD reading of "ON TRANSMIT
ON" indicates both transmitters are on. Press + or – touchpads to adjust.
Note: Switching off the transmitter in either panel does not reduce detection or the ability of
the PD-6500 i to indicate the target's vertical position with its zone lights. However, switching
off either transmitter does eliminate the PD-6500 i 's ability to indicate the target's horizontal
position with separate left and right zone lights. With either transmitter switched off, the PD-
6500 i is operating as a single-sided detector. It therefore can not resolve the target's
horizontal position, as is the case with conventional, less advanced detectors.
