Optional External Antenna
The modem can use an optional external antenna (purchased
separately) to increase performance in fringe reception areas.
To access the External Antenna Connector:
1. Locate the External Antenna Connector on the side of the
device.
2. Remove the rubber protector to expose the External Antenna
Connector. (Keep the rubber protector in a safe place for future
use in order to protect the External Antenna Connector from
debris when not in use).
