Mounting the 7845GSM
The 7845GSM must be mounted
indoors
. To mount the 7845GSM, see
Figure 1
and
complete the following steps:
1.
Unpack the 7845GSM and detach the case back by pushing up into the two tabs located
at the bottom of the 7845GSM with the blade of a screwdriver while pulling the case
back and case front apart.
2.
Temporarily connect the 7845GSM to the AC transformer, supplied.
3.
Choose the installation site with the
best signal strength
by observing the signal
strength (RSSI) bar graph (refer to
Section 6
for information about signal strength and
status indications). Signal strength should be within 3-5 bars. The best signal strength
is usually found at the highest point in the building, near a window. Unplug the
transformer.
