We recently deployed 130 7921s company-wide. About 10-15 of these 7921s get stuck at "locating network services". We've reset to factory settings and manually reconfigured, same end result.
We've discovered after trying several different batteries, device will eventually auto-register.
Also, the battery that doesn't work on the 10-15 7921s, work fine on other functional 7921s.
It's like certain 7921 batteries don't work on certain 7921s. Is there any known issue of this sort?
Should we just RMA these units for a warranty replacement?
