However, if necessary (possibly due to lack of ability to communicate with the unit due to
misconfiguration), a hardware reset procedure is provided below.
To return the AVN422HD to the Factory Default settings:
1. Remove the AVN422HD blade from the chassis (see
2.1 Blade Installation and Removal
).
2. Locate the Factory Default DIP switch near the top center of the AVN422HD blade's PCB.
3. If present, remove the plastic cover from the DIP switch.
4. Set the left DIP switch into the Factory Default position as labeled on the unit.
Warning: Do not change the position of the other dip switch.
5. With the chassis powered on, insert the AVN422HD blade back into the chassis.
Warning: Do not remove the blade or turn off power to the unit until the default
is complete as described below.
6. Observe the Status and Video LEDs on the front of the unit.
7. Wait for these lights to be "solid" on (no blinking); this indicates that the default reset is
complete.
8. Remove the blade from the chassis to return the DIP switch to the Normal Operation setting,
then re-install the blade.
