PROCESS UPDATE:
Update as of 14 JAN 2025
The batteries that are included in the remote controls are CR 2025.
They are 2.5mm thick however, they are a bit loose for the remote controls.
A customer has tried using CR 2032 batteries, which are 3.2mm thick, and these batteries work fine with the remote.
L1: If you will encounter similar issues in the future, try to advise changing the batteries first.
If customers have a spare CR 2032 batteries, then, it would be better.
Forward to L2 for further assistance if needed.
