Note
When any communication connector is not in use, it should be
capped. The cap will seal the connector to prevent corrosion,
prevent moisture from entering the unit, and improve communi-
cations.
Note
For the transmitter to comply with FCC Maximum Permissible
Exposure (MPE) regulations, the antenna needs to be located
a minimum of 30 centimeters (12 inches) from the human
body.
