Antenna

CAUTION
(1) If installing the antenna under the desk, use a dedicated stay (optionally available).
(2) RF tags are read using radio waves. Reading performance may be lower if there are any metal objects (other than the
dedicated stay) or equipment using radio waves (mobile phones, amateur radio stations, microwaves, etc.).
Before installing the antenna, check for such problems.

Notes:
(1) If the plate thickness of the antenna mounting stay is 2 mm (t = 2 mm), it can be secured with the screws L = 6 mm included in
the package.
If the plate thickness of the antenna mounting stay is not 2 mm (t ≠ 2 mm), use screws whose length of thread engagement is 3
to 4 mm inside the antenna.
(2) If you fail to tighten them to recommended torque (0.53 to 0.95 N-m), they may be incompletely tightened.
(3) The screws may gradually become loose depending the stay material/surface treatment and/or the surrounding environment.
Check the installation of the scanner at regular intervals while in use.
