the switch, or (if they are powered by direct current) connect them to the corresponding
DC output connections on the terminal block (
Figure 12 ) at the rear of the switch.
3. Perform any optional steps required for your system
4. Upon initial power-up, the front panel LED should be lit, indicating that the internal
power supply is operational.
3.6 The Setup Button
The setup button is used to calibrate all channels on the Redundant Amplifier switch. Upon
initial installation default thresholds will be used.

The default threshold settings for the Redundant Amplifier Switch are:
Minimum Threshold = 4 dB
Maximum Threshold = Disabled
After installing the unit, locate the setup button on the rear panel of Redundant Amplifier
switch. It is located under the frame ground screw on the lower-left side of the panel (see
