4-1-4 How to Install Tag

Installation
Install a tag on a flat plane taking care not to bend it by force. As shown below, mount the antenna with two M4 screws, spring washers
and flat washers. Tightening torque is 1.2 N•m (approximately 12 kgf•cm). Do not use any lock paint to fix screws.

Influence on communication performance, adhesive, metal tape, water screen, etc.
•
When you apply adhesive, etc. on the tag surface, a radio wave (microwave) is attenuated and the communication area may be
affected. Execute the communication experiment with anything used actually in advance.
•
If a metallic tape, etc. is put on the tag surface, a radio wave is interrupted and the communication to the antenna fails.
•
If the tag is put on a glass plate with double-sided adhesive tape as shown below, a gap between the glass plate and tag sweats easily.
Moreover, a water screen may be generated. In this case, please note that a radio wave is absorbed and the communication range
may become small.
