Issue
CM4000 meter reboots itself intermittently.

Product Line
CM4000, CM4000T

Cause
Sending an IRIG-B time synch signal (instead of a DCF-77 format signal) into a digital input configured for time synch on the CM4000 causes it to reboot randomly.

Resolution
Ensure that the proper I/O format signal is connected to the CM4000.
The CM4000's can only accept DCF-77 time synch signals.

Kindly refer to page 72 of the CM4000 Reference Manual for more details on time synch signals.
