time. In most cases however, the signal should be
available continuously. If you experience a loss of
signalor audio, reposition the antenna inside the
home or outside as necessary.
6. Antenna Placement Considerations
The antenna should be placed on a relatively flat
surface whenever possible. When outdoors, the
antenna may be left in its mount atop the Boom
Box provided no overhead obstructions are present.
To mount the antenna:
a.Plug the antenna into the ANT connector on the
back of the JSIR900B.
b.Leave the antenna in place on the Boom Box,
or remove the antenna from its mount, uncoil
the antenna lead, and place it at the preferred
location inside or outside the home. If no audio
is heard, move the antenna to different positions
on the surface until an audio output is heard. This
is the desired antenna position and, if indoors,
should be marked.
c. After determining the optimum position, turn
off JSIR900B and Receiver power. Disconnect the
poweradapter from the wall outlet receptacle
(if indoors) and disconnect the antenna cable.
d. Plan the routing of the antenna cable to the JSIR900B
ANT input when indoors. Make sure you avoid any
obstructions that could crimp, kink or twist the cable;
use protective grommets wherever rough openings
are encountered. If the antenna is mounted outside,
route the cable from the antenna position to the
interior of the home, working the cable through the
basement, under a window sill, etc.; make
adjustments and take up slack whenever necessary.
e. If outdoors, either leave the antenna in place atop the
JSIR900B, or remove the antenna and find a location
free from overhead obstructions such as tree
branches, or the roof of a tent or other temporary
shelter.
f. Plug the antenna cable into the ANT connector on
the back of the JSIR900B.
g. If not using battery power as the primary power
source, plug the female end of the DC adapter cable
into the DC 12V receptacle on the rear of the JSIR900B.
h. Plug the other end of the DC adapter cable into a
110-volt receptacle. Apply power to the Boom Box
and Receiver.
