6. Wait approximately 10 seconds for the removal to complete. As soon as you hear three tones, your tag has been successfully removed and will automatically go into pairing mode for 10 minutes. You can now pair it to another phone. After 10 minutes, if the tag is not paired with another phone, it will exit pairing mode. To place it back into pairing mode, remove the battery, wait 10 seconds, and reinsert the battery. After you hear the tones, your tag is in pairing mode.
