Attaching the Antenna

The antenna picks up radio signals from or sends signals to the Intermec 9181
Base Radio Unit, 9183 Radio Repeater, or 0100 Access Point. Attach the antenna
to the connector on the top of the JANUS 2050. Keep each JANUS 2050 at least
2 feet away from another JANUS 2050 or any other radio. Two antennas within
2 feet of each other may damage the radio receivers.

CAUTION

Caution
The antenna must be attached before turning on the JANUS 2050. The internal
radio could be damaged if the antenna is not attached.

Conseil
Si l'antenna n'est pas attachée avant que la JANUS 2050 soit mise sous
tension, la radio interne peut être endommagée.
