X15-41-01 Pendant -- Which revision?

This is Pattern 2: a chooser parent plus revision-specific child pages. Use it when revisions diverge substantially. The parent carries the search identity (“wireless pendant”) and asks the identifying question so readers — and bots — land on the right variant instead of an orphaned duplicate.

Which revision do you have?

Check the sticker on the back of the pendant for the serial number.

Rev A

Serial below 20000, dongle-style USB receiver.
