If you wish to use it wirelessly by Bluetooth, it may or may not need updating depending on the following criteria. To confirm that your unit requires the update, please check that all of the following are true:

2. The ID number is lower than 6341. Only units with ID numbers lower than 6341 need the update. The ID number is located on the top label.
3. The unit hasn’t already been updated. A small silver dot on the label located on the bottom of the unit indicates that the update has already been performed.
