Do not install the Telguard in an area where the general public could reasonably be
within 20cm (8 inches) of the antenna.
NOTE 1: Optimum RF performance can usually be found at the highest point within a
building with the fewest number of walls between the Telguard unit’s antenna and
the outside of the premises.
NOTE 2: To avoid interference with other electronic devices operating in the area,
avoid mounting the Telguard’s antenna near other electronic devices.
NOTE 3: The Telguard’s antenna is designed for indoor installations only.
These considerations should be coupled with the best RSSI indication obtainable.
Care should be taken to ensure that a large metal object such as a refrigerator or
a metal cabinet is not located on the opposite side of the wall.
If moving the Telguard to a different location is not practical, you may need to
get an extension cable and remote the antenna in order to receive adequate radio
signal strength.
Pick a high, visually secure spot using the guidelines below.
Tips for Improved Radio Signal Reception
The higher the antenna the better.
Start in the drop ceiling above the unit
and proceed from there, up to the roof if necessary.
Remember, the antenna should be as inconspicuous as possible for greatest
visual security.
Try to keep the antenna away from sources of RF interference, including pumps,
compressors, ovens, etc., or where metal objects can shield it or otherwise
block the cellular radio RF signal.
Place the antenna perpendicular to the ground, either right side up or upside
down.
Do not mount the antenna horizontally.
Measure Received Signal Strength (RSSI) for Best Antenna Placement
Measure the received signal strength by pressing the RSSI button. This switches the
LEDs to signal strength mode.
Now, slowly move the unit or remote antenna to
achieve maximum signal strength.
Pick a spot where the most LEDs (up to four) are
illuminated.
