Antenna Selection
Under FCC, Industry Canada, COFETEL and ANATEL regulations,
this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by the FCC, Industry
Canada and ANATEL. To reduce potential radio interference to other users,
the antenna type and its gain should be so chosen that the equivalent
isotropically radiated power (e.i.r.p.) is not more than that necessary for
successful communication.
The EVM-915-250-FCx radio transmitter has been approved by the FCC
and Industry Canada, the EVM-915-250-CFx and the Wi.232FHSS-
250B-xx-R has been approved by ANATEL to operate with the antenna
types listed in Figure 10 with the maximum permissible gain and required
antenna impedance for each antenna type indicated. Antenna types not
included in this list, having a gain greater than the maximum gain indicated
for that type, are strictly prohibited for use with this device.
An approved antenna must be directly attached to the module’s reverse-
polarity SMA connector in the final application to inherit the modular
certifications.
Module Modification
The module must not be physically altered in any way. If any connections
are made to the modules that bypass the module pins, socket or antenna
connector, none of the modular certifications can be inherited.
Product Labeling
The end product must be labeled to meet the FCC product label
requirements. It must have the below or similar text:
Contains FCC ID: Q7V-3F090009X / IC: 5589A-3F090009
The Brazil version must contain:
Anatel: 0946-08-4266
The label must be permanently affixed to the product and readily visible to
the user. ‘‘Permanently affixed’’ means that the label is etched, engraved,
stamped, silkscreened, indelibly printed, or otherwise permanently marked
on a permanently attached part of the equipment or on a nameplate of
metal, plastic, or other material fastened to the equipment by welding,
riveting, or a permanent adhesive. The label must be designed to last
the expected lifetime of the equipment in the environment in which the
equipment may be operated and must not be readily detachable.
