Meter has been in 
service for an 
extended period of 
time and begins to 
work erratically 
such as loss of 
Work Orders or 
Security settings.

E-Prom on meter board has reached 
the end of its life.

Attempt to reprogram the meter. If you see a pop-up 
screen on the PC that says, “Memory Failure” and/or the 
meter screen defaults to the ACTIVATE/ACTIVATE 
screen, the E-Prom on the meter board must be 
changed. Install the Electronics Repair Kit (246675). 
The Electronics Repair Kit includes a new meter board 
with E-Prom. The meter then can be reprogrammed to 
the features desired.
