ATTENTION
The antenna cables should not be modified (i.e. cut short
and/or re-terminated) as it may affect Communication Agen-
cy approval.
m
WARNING
The WMPR must be installed in accordance with the require-
ments specified in this document in order to comply with the
specific Country Communication Agency requirements. (i.e.
FCC, IC, ACMA, etc.) See Section 3 as it requires choosing the
correct Country Use Code and thus allowable antenna and/or
cable usage.

WARNING
RF EXPOSURE
To satisfy FCC RF exposure requirements for mobile
transmitting devices, a separation distance of 20 cm [7.87
in] or more should be maintained between the antenna of
this device and persons during device operation. To ensure
compliance, operation at closer than this distance is not
recommended. The antenna used for this transmission
must not be co-located in conjunction with any other
antenna or transmitter.
Failure to comply with these instructions could result in
death or serious injury.
,
CAUTION
Power to the WMPR should not be applied during installation
of an antenna as damage could occur to the WMPR electron-
ics.
8.5.1 Antenna Connection
Physical connection of the antenna to the WMPR is accom-
plished by using mating RP-SMA connectors: plug and jack.
Direct-mount antennas have an RP-SMA plug that connects
directly to the WMPR RP-SMA jack. The remote mount anten-
na uses a cable with a RP-SMA plug that connects directly to
the WMPR RP-SMA jack allowing the antenna to be remotely
mounted away from the WMPR. Mounting options are based
on user preference, communication agency approvals, WMPR
mounting location, and obstacles as discussed in Section 8.3.1.
A direct- or remote-mount antenna can be easily mounted
by threading the mating RP-SMA plug of the antenna to the
WMPR’s RP-SMA jack. Reference section 8.6 for further details
on extra environmental protection of RP-SMA connections.
Tighten the RP-SMA connection until finger tight. See Figures
48 and 49.
