2.7 Removal and Replacement Information
2.7.1 400W Series Unit
If the 400W Series unit is removed and reinstalled, verify that the 400W Series unit power-up self-test
sequence is successfully completed and no failure messages are annunciated.
If the 400W Series unit is removed for repair and reinstalled, or if the 400W unit is removed and replaced
with a different 400W Series unit, then follow ‘Post Installation Configuration & Checkout Procedures’
contained in the 400W Series Installation Manual (P/N 190-00356-02), listed in paragraph 2.1 of this
document, and verify the 400W unit power-up self-test sequence is successfully completed and no
failure messages are annunciated.
If any work has been done on the rotorcraft that could affect the system wiring, antenna cable, or any
interconnected equipment, verify the 400W Series unit power-up self-test sequence is successfully
completed and no failure messages are annunciated.
To remove the 400W Series unit from the mounting rack, insert a 3/32-inch hex drive tool into the access
hole at the bottom of the unit face. Rotate the hex tool counterclockwise until the unit is forced out about
3/8 inches and can be freely pulled from the rack.
The 400W unit is installed in the rack by sliding it straight in until it stops, about 1 inch short of the final
position. Insert the hex drive tool into the access hole at the bottom of the unit face. Rotate the hex tool
clockwise while pressing on the left side of the bezel until the unit is firmly seated in the rack.
Note: There are no special handling requirements for the 400W Series units.
