Checking the firmware version of your N95 respirator is important to ensure that you have the latest updates and bug fixes. The firmware version can be found on the back of the respirator, next to the battery compartment. It will be a four-digit number, such as “1.02” or “1.03”.
If you have an older version of the firmware, you can update it by following the instructions in the user manual. Updating the firmware can improve the performance of your respirator and fix any bugs that may be present.
