3 Precautions
3.1 Handling precautions
The module must be handled with special care, keeping the following precautions in mind.
The module is an inductive-type read/write communication device that is type-certified in compliance with
the Radio Law of Japan. The operating frequency is 13.56 MHz. Disassembly or modification of the
module, removal of the type number or similar acts are subject to penalties according to applicable laws.

module, removal of the type number or similar acts are subject to penalties according to applicable laws.
Be sure to use a stable power supply so that the module can be protected from the effect of noise and
excessive voltage peaks, such as lightning, transmitted through the power supply connector.

Do not cause any chemical or physical damage to the module.
Do not subject the module surface to contaminated air or materials.
Tightly ground not only module after installation but all jigs, ma
chines, workbenches and workers’ bodies
to prevent static electricity from affecting the module.
For safety’s sake, be sure to wear gloves when handling the module, although its surfaces are carefully
finished.
finished.
Protect the module from interference from other wireless machines.
Do not install the module in an environment where a strong electromagnetic field may exert deleterious
effects on communication performance. Take special note of the installation location so that interference
between the module and other equipment can be adequately controlled.

The interface cable (FFC / FPC) is not supplied, making it necessary to prepare the one appropriate for
your system. When selecting the cable, make sure to connect a cable in the right direction because the
connector has a double terminal.

approximately 90 degrees above when unlocked.
Measures for static noise and power line noise must be designed and incorporated on your own.
Especially, if the module is connected to two or more system ground ports which have a difference in
electric potential, it may depreciate communication performance and cause unexpected noise.

Treat an antenna carefully. Damage of an antenna or change of antenna characteristics may occur by
bending, pulling, twisting, press or brandishing it strongly. For the same reason, do not tear off the
antenna once stuck on adhesive tape or a cabinet.
