out NIC boards and exchange them between meters.
To replace a NIC board:
1. Connect an ESD grounding strap and observe ESD precautions when
handling boards.
2. Remove the meter from its socket
3. Grab and rotate the front cover ¼ turn counter-clockwise until it releases (as
described in the Meter User Guide).
4. Pinch the dual gray meter latches on the left side and right sides of the meter
to release the meter module from the meter base.
5. Disconnect the NIC and remove it from the assembly.
6. Disconnect the antenna UFM connection from the board.
7. Attach the antenna wire to the new NIC.
8. Insert the new NIC in place of the old one.
9. Reattach the meter module to the meter base by pressing the module against
the base until the dual latches spring open and catch on the black tabs.
Ensure both the left and right sides are seated.
10. Replace the meter front cover.
11. Re-insert into test socket to power device.
12. At power-up you may see red and/or blue LEDs temporarily light then
extinguish. The LEDs are described in LEDs on page 56.

reconfigure the NIC and ensure that it is functioning properly.
