TIPS & TROUBLESHOOTING

Lock Sounds Beep Twice: When Bumpbar's batteries run low, Lock Sounds occurs twice (two one-second beeps instead of one two-second beep). Replace Bumpbar's AA batteries soon.
Bumpbar Fails to Pair: If you Bumpbar fails to pair after multiple attempts (especially one that had been previously paired with another host device), you may need to forget pairing info and try again (see Unpairing Bluetooth® Bumpbar).
Increase Battery Life: Bluetooth® Bumpbar should operate for one year (or longer) on a single set of 2x AA alkaline batteries but can be configured to conserve battery by turning off Lock Sounds and Button Chirps (see Using Local Configuration on Bluetooth® Bumpbar).
