Feature Description
Test point A
This test point enables monitoring of the RF level at the input to
the A/D. It measures −20 dB from the A/D input level.

setting
The transmitter has a digitally controlled attenuator that adjusts
for varying input levels. This push-button is an input level-control
adjustment that provides +2 to −13 dB of adjustment from an
input level of 15 dBmV.
Short press (0.1 to 1.5 seconds). The status LED indication is
green with a short OFF blink (0.25 sec.) when the button is
released. A short red blink occurs if the increment attempts to go
past the maximum.
Short press (0.1 to 1.5 seconds). The status LED indication is
green with a short yellow blink (0.25 sec.) when the button is
released. A short red blink occurs if the decrement attempts to
go past the minimum.
Medium press (1.5 to 5.0 seconds). The status LED is OFF after
1.5 seconds when in the increment direction, and yellow when in
the decrement direction. The LED is restored to its green or
alarm state when the button is released. No increment or
decrement occurs.
Long press (5.0 seconds or longer). The status LED flashes
green and yellow rapidly until the button is released. After five
seconds of flashing, the factory defaults are restored.
Status
This tri-color LED is green if all parameters are within
specification. A series of red flashes indicate an alarm condition.
The number of red flashes indicate the parameter that is outside
the specification.

It is recommended that you restore the factory default settings before you set up the node levels. This
procedure places the transmitter input level 2 dB below maximum.
