Initializing INTEGRATED NETWORK AV RECEIVER

INTEGRATED NETWORK AV RECEIVER initialization should be performed when the μcom, peripheral parts of μcom,
and Digital P.W.B. were replaced.
1. Turn off the power pressing ON/STANDBY button.
2. Press ON/STANDBY button while simultaneously while pressing PRESET CHANNEL 2 and PRESET CHANNEL 3
buttons.
3. Check that the entire display is flashing at intervals of about 1 second, and then release the 2 buttons.
