General InformationHow do I retrieve the unlock PIN of my Xen?
If you have lost the unlock PIN of your Xen and need to re-enter it (e.g. after a software update) you can retrieve it by logging in at Update Owner Info. You will need to provide your email address, the password you chose when registering your unit as well as your unit's serial number. You will then be able to see your PIN at the very top above your contact information.
Xens with serial numbers 1251 and higher can use 3.6V lithium 17335M disposable batteries as well as 3.6V lithium ICR16340 rechargeable batteries. These units have a white battery holder.
Xens with serial numbers 1250 and lower which have a black battery holder only work with 3.6V lithium ER14335M batteries. However these units can be upgraded to the white battery holder for a fee of $99 (North America, incl. return shipping) or $129 (International, incl. return shipping).
For the different battery options that are available please review our battery information chart.
The ER17335M batteries can provide up to 92 hours of dive time with your unit (low brightness, green font, battery used within a month of initial use), although 40-60 hours is more typical.
The older ER14335M batteries can last up to 46 hours, however 20-30 hours is more typical.
The life of your battery greatly depends on various factors such as the colours you choose, the brightness and refresh rate you set your display to, the water temperature etc. You can find a detailed overview on the factors that influence your battery life and how to optimize it on our battery information page.

Xen TroubleshootingAt the end of the installation process I see six "PASS" and one "FAIL" in the uploader.
When updating your unit's software you should either see seven "PASS" or six "PASS" and one "FAIL" at the end of the uploading process followed by "resetting your dive computer". In both cases your software will have installed properly and everything should work just fine.
To verify that the install succeeded pick up your unit, enter the main menu, and go to Preferences->Status, and the software version should be the same as the version that you tried to install (e.g. 2.25).
When connecting your unit to your Mac or your PC whether for updating the software or for downloading your dives please make sure that:
- If you have a PC: The drivers and our software is installed.
If you have a Mac: Our software is installed on your Mac (no need to install the drivers)
You can find download and installation instructions here.
- Your unit is aligned properly with your PC Interface
- Your unit's battery is not empty
- If it doesn't work immediately, rearrange the unit and the PC Interface a little and try again
If you have trouble updating your unit's software please make sure you followed the steps outlined above. If you are still having trouble we compiled documents with detailed instructions for PC Owners and for Mac Owners.
When downloading your dives please make sure you follow the procedure outlined above under questions 2 and 3.
Also when initiating the download of your dives you have to tap into your unit and select "Connect to PC" in the main menu. After that place your unit on your desk and align it properly to the PC Interface. You have about 20 seconds from when you tapped "Connect to PC" to start the download process on your computer. If you take too long the operation will timeout and you will have to try again.
