Tuning Procedures & Tips
There are mainly two problems that affect system’s functioning and
performance. One is that system picks up tags and labels poorly. The other is
that system false alarms (or causes other system to do so) without tags or
labels in detection zone.

Low Pick up Rate
1. Check noise “D” (ranging from 0-
999, >100 or so is big noise & >400
is heavy noise).
2. Adjust MIN, GN & RE to increase
sensitivity (see diagram below).
3. Adjust POT for Rx signal pre-
process sensitivity on TX board (see
page 18).
4. Shorten pedestal separation or use
stronger tags (e.g. Super Pencil).

Interference with or by other
systems
1. Swap L & N terminals on power plug
of control pack.
2. Adjust SYN “B” step by step to align
up with other systems.
Please open and tune the systems one by one if there are multiple systems
installed. It will help determine which system is causing the problem.
