User's Manual

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including any interference that may cause undesired
operation.
The user manual for the end product must include the following information in a prominent
location:
To comply with FCC’s RF radiation exposure requirements, the antenna(s) used for this
transmitter must be installed such that a minimum separation distance of 20cm is maintained
between the radiator (antenna) & user’s/nearby people’s body at all times and must not be
co-located or operating in conjunction with any other antenna or transmitter
The ZX-R8204 is compatible with many varieties of antennas, but for purposes of modular
certification with FCC, only one antenna was tested. ZX-R8204 users can have their own
antenna and ZX-R8204 systems certified with FCC and IC.
In order to operate the ZX-R8204 under either FCC ID: 2AYIXZX-R8204, the OEM must
strictly follow these antenna guidelines:
• The OEM may operate only with the following antenna or antennas of the same type with
maximum gain as shown:
circularly-polarized patch antenna with 6.29 dBi linear far field gain
• RF I/O interface to the antenna connector on the PCB shall be accomplished via a
microstrip or stripline transmission line with characteristic impedance of 50 ohms +/- 10%. A
custom coaxial pigtail may also be utilized to connect to the antenna in lieu of a connector.
• The connector on the OEM’s PCB which interfaces to the antenna must be of a unique
type to disable connection to a non-permissible antenna in compliance with FCC section
15.203. The following connectors are allowed:
• The OEM must professionally install the ZX-R8204 into its final environment to ensure
that the conditions are met.
The minimum safe distance for people from the ZX-R8204 has been determined by
conservative calculation to be less than 20 cm for the allowable antenna types. The end
product User’s Guide must include the following statement in a prominent location:
To comply with FCC’s RF radiation exposure requirements, the antenna(s) used for this
transmitter must be installed such that a minimum separation distance of 20 cm is
maintained between the radiator (antenna) & user’s/nearby people’s body at all times and
must not be co-located or operating in conjunction with any other antenna or transmitter.
