JTBL Regulatory Notices

Antenna

According to Japan regulatory rule, module certification is valid only with the specific

antennas registered to and approved by JRL certified body in relation to module

certification. Customers who are going to use modules under Japan Radio Law, are

responsible to contact Telit technical support or sales to get the list of these antennas.

Dial Function

The JTBL Module Certification for “LE910C1-AP” is for “non-Auto Redial Function”

device.

In case customer implement “Auto Redial” function into Application Device by controlling

LE910C1-AP, the customer cannot utilize LE910C1-AP JTBL certification, and they must

apply JTBL as “Application Device” System.

NCC Regulatory Notices

According to NCC Taiwan requirements, the module and the packaging shall be identified

as described in the following lines. Shall be added also the specified safety warning

statement.
