3.0 ALIGNING THE ANTENNA
3.3.1 Signal Strength and Alignment
When power is first applied an audible signal (beep) will occur. Faster beeping indicates higher signal strength.
Adjust the unit first panning left and right, then up and down until the rate of beeping is maximized. If the unit is
difficult to tilt or turn, loosen the locknuts on the V-bolts slightly.
If the beep rate is very quick, the beeps will continue to be heard for ~3mins and then stop. This quick beep rate
indicates that very little movement is necessary. If the beep rate is slow, the beep will occur for 20 minutes at
minimum signal strength of less than –80 dBm. This slow beep rate indicates that more movement is required.
Once antenna alignment is complete, tighten the locknuts to secure the TRI1819 to the pole.
3.3.2 Resetting the Beeper
To reset the timer for alignment, simply unplug the power supply from its AC connection. Wait 5 seconds, then plug
the power supply back into its AC connection. The beeper will begin beeping as soon as power is available.
