Step 1: Turn off electricity at fuse or circuit breaker before proceeding!
Step 2: Remove the unit from the mounting plate by pressing both circular snaps at the bottom of the housing. Rotate the housing upward and pull it firmly away from the mounting plate (which will remain mounted on the wall).
Step 3: Check the label inside the fixture to verify the Catalog number is one of the following:
ELM CSR ELM2 B
ELM DL ELM2 DL
ELM2 USPOM ELM2 B DL
ELM2 NOM ELM2 220-240V 60HZ
Step 4: Check the color of the circuit board. If the circuit board is solid green front and back, you will need a replacement board.
If the fixture has a solid beige or combination beige/green boards, no further action is needed.
