User's Manual

If there were high interference, the system will shut itself off to avoid false alarm. To ensure the system will
operate well, must try and eliminate obvious cause of interference. Then, follow the below instructions:-
1. In Tx, adjust VR14 until Sw reads 700 ~ 750.
2. In Rx, change jumper in JP1, moving one slot to the right i.e. from position 1/2 to 2/3. This is the case
when there is high noise interference and detection distance is more than 1.5m.
3. In Rx, change jumper in JP2, moving one slot left i.e. from position 2/3 to ½. This is to eliminate the
self-locking function at high noise interference.
4. In Rx, adjust VR1 until only DS1 light flashes.
5. In Rx, select SW1-4 to ON and SW1-5 to OFF.
6. Press RESET.
If there is large metal objects close-by, may see if grounding it to the Rx antenna base labeled GND at P1
(connecting with wire) will improve interference. If no improvement, remove this grounding.
The above adjustment is only suitable for hard tags use only and not for labels. The parameters for labels
are weaker thus with the above adjustments, unless the labels are very made, detection would be poor.
Attention!
The users manual or instruction manual for an intentional or
unintentional radiator shall caution the user that changes or modifications not expressly
approved by the party responsible for compliance could void the user's authority to operate
the equipment. In cases where the manual is provided only in a form other than paper, such as
on a computer disk or over the Internet, the information required by this section may be
included in the manual in that alternative form, provided the user can reasonably be expected
to have the capability to access information in that form.
