Adjusting Gate 1 and Gate 2 Sensitivity

If force is set too sensitive false sensing may be observed.

IMPORTANT: If adjusting for a single gate, once adjustment for that gate is set, also set the

other sensitivity adjustment to the same setting. Adjusting both Gate 1 and Gate 2 sensitivity

adjustments to the same setting for a single gate installation will prevent the possibility of

false trigger and gate reversal.
