3.2 Antenna Options
The 2103C antenna connector design has recently been updated.
Operation is exactly the same for both versions.
The two versions of the module are distinguishable from one
another by the appearance of the antenna connector. The earlier
connector type has slightly different steps for connection to the
m o d u l e. I f y o u r m o d u l e h a s t h e l a r g e r s i d e c o n n e c t o r
(Figure 3-1-A, below), follow the instructions in Section 3.3,
Antenna: Early Version . If your module has the smaller side con-
nector (Figure 3-1 -B, below), follow the instructions in
Section 3.4,
Antenna: Current Version .
An adaptor cable is available for connecting early-style antennas
to the current module (part #60-5314-891).

3.3 Antenna: Early Version
One of three antenna types is included with your system, spec-
ified when ordering: the magnetic mount antenna, the in-street
antenna, and the manhole lid-mount antenna.
Note
For the transmitter to comply with FCC Maximum Permissible
Exposure (MPE) regulations, the antenna must be located a
minimum of 30 centimeters (12 inches) from the human body.
Note
When any communication connector is not in use, it should
always be capped. The cap will seal the connector to prevent
corrosion, prevent moisture from entering the unit, and improve
communications.
