Tip: When using a cable to an antenna placed away from the modem, minimize the length
of your cable. All gain from a more advantageous antenna placement can be lost with a
long cable to the modem.

Your Raven XT can be used with either DC or AC, with the appropriate power
adapter. DC cables and AC adapters are available as optional accessories in
addition to the one included with your Raven XT.
Note: When using a DC
power source (such as a
solar cell), Sierra Wireless
recommends placing a
fuse (1-2 Amp) on the line
close to the power source
to protect your power
source from possible
surges due to shorts or
other line issues.
The DC power cable positive lead should be connected to the battery or power
source positive terminal. The power cable negative lead should be connected to
the battery or power source negative terminal.
Tip: The DC power cable has a white wire lead in addition to the power positive and
negative. This is for a feature not present in the Raven line modems. In the Raven XT, the
white wire lead has no function and can be ignored.
Warning: Explosion Hazard - Do not disconnect equipment unless power has been
switched off or the area is known to be non-hazardous.
