       [The modular transmitter must be            See Label Exhibit
       lequipped with either a permanently affixed
       label.


         [The modular transmitter complies with all    Instructions in User Manual
         ispecific rules or operating requirements
         ithat ordinarily apply to a complete
         transmitter and the manufacturer will
         jprovide adequate instructions along with
         the module to explain any such
         requirements. A copy of these instructions
         is included in this application for
         equipment authorization:

         |Address compliance with the                 Instructions are given in the installation
         Commission‘s RF exposure limits in           manual for compliance to the RF
         Sections 1.1310 and 2.1093. In addition,     exposure requirements.
         spread spectrum transmitters operating
         lunder Section 15.247 are required to
         laddress RF exposure compliance in
         laccordance with Section 15.247(b)(4).

A limited modul:      pJ roval may be granted for single or split modular transmitters that do not comply with
all of the above requirements, e.g., shielding, minimum signaling amplitude, buffered modulation/data inputs, or
power supply regulation, if the manufacturer can demonstrate by alternative means in the application for
equipment authorization that the modular transmitter meets all the applicable Part 15 requirements under the
operating conditions in which the transmitter will be used. Limited modular approval also may be granted in
those instances where compliance with RF exposure rules is demonstrated only for particular product
configurations. The applicant for certification must state how control of the end product into which the module
will be installed will be maintained such that full compliance of the end product is always ensured.
