GTM-1 Operational Description
8 FCC Certification
The GTM-1 is FCC certified as a ‘mobile device’, which requires a minimum distance
of 20 cm between the application’s antenna and the human body.
Per FCC Section 15.21, any changes or modifications to the GTM-1 not expressly
approved by Wavecom could void the user's authority to operate the equipment.
Users and installers must be provided with antenna installation instructions and
transmitter operating conditions for satisfying RF exposure compliance.
Wavecom’s FCC ID may be used by the integrator if the following conditions are
followed:
1.
The application must be implemented as a “mobile device” and not a “portable
device.”
2.
The application’s user and installation manuals must include a statement that
a minimum distance of 20 cm between the antenna and the human body is
required.
3.
The antenna system gain must be within the following constraints:
a)
850 MHz Band: the antenna system gain must not exceed 6.76 dBd
gain.
b)
1900 MHz PCS Band: the antenna system gain must not exceed 8 dBi
gain.
4.
The licensed module will have a FCC ID label on the module itself. The FCC ID
label must be visible as defined by the FCC (visible through an open access
door is permissible), or a separate label must be similarly visible that conveys
the message: “Contains Transceiver Module FCC ID: O9EGTM1.”
