3. Gradually turn the sensitivity adjustment screw located on
the bottom of the TVA50 (Figure 6) until you hear the inter-
nal relay of TVA50 switch. This is indicated by a clicking
sound inside the unit. The Power/Active LED on the front
panel of the TVA50 (Figure 7) provides a visual indication of
the local switching. When the TVA50 switches to the local
input the Power/Active LED will change from red to green.
4. Cycle the power of the local source component on and off.
Adjust the sensitivity setting of the TVA50 until the internal
relay switches reliably.
NOTE:
The TVA50 may be set to operate continuously by turning
the sensitivity screw fully counterclockwise. This will bypass the
internal sensing mechanism.
