a Digital Multimeter (DMM).
Test:
1. Power on the RV-8.
2. Turn on the DMM and set it to read DC voltage for a 12V level.
3. Using the remote control Menu arrow, select SETUP from the Main Menu.
4. Scroll down through the SETUP menu and select TRIGGERS.

6. Press the remote control MAIN button, then press the remote control DVD1 button to select DVD1 as
the input for the Main Zone.
7. On the RV-8 rear panel, locate the Trigger Outputs block.
8. Connect the DMM’s red probe to positive (+) and connect the black probe to negative (–). Measure
the PWR +/- and the #1 +/- trigger outputs for 12 Volts DC.
RS232 Test
