A TIRIS RF module generates RF emissions at 127 to 142 kHz. The radiation of the fundamental and harmonic frequencies varies with the type of antenna and other devices or functions connected to the RF module.

Before operating a TIRIS RF module with an antenna, power supply, and a control module or other devices, the required FCC or PTT approvals must be obtained.

Sale, lease, or operation in other countries may be subject to prior approval by the government or other organizations.

This reader can only be operated or marketed if the relevant FCC, PTT, or other government agency has issued an equipment authorization for a complete system.

For marketing functional systems within the European Community, a Declaration of Conformity to European EMC laws is required.
