2.7.1 LED Signal Strength Indication
The Telguard provides the installer with an easy to use LED radio signal strength indicator (RSSI) for
positioning the unit or remote antenna to obtain the strongest RF signal possible. A signal strength
reading can be obtained at any time there is power applied to the Telguard without affecting the
operation of the unit. When the
“RSSI”
jumper J10 is “SHORTED”, the Telguard displays the current
received signal strength within 5 seconds. The signal strength is read from left to right using the four
sequential LEDs located on the top right side of the printed circuit board with the
Radio TX LED = 5
and the
STC LED = 2
. See Appendix A1.4 for RSSI table.
