PM5 monitors on indoor rowers and SkiErgs manufactured prior to 4/14/2015 may be prone to a number of issues relating to loose batteries in the battery compartment. Potential issues include spontaneous resetting, flickering back light and error messages.
To address these issues, we have redesigned the battery door to better retain the batteries. As an interim solution, we added a foam pad in the battery door between 4/14/2015 and 7/14/2015.
To identify the age of your PM5, inspect the serial number on your indoor rower or SkiErg (see these page for more information on serial number location by machine: Model D | Model E | Dynamic | SkiErg). The first group of numbers represents the date the unit was boxed. If these numbers indicate a date earlier that 4/14/2015, we recommend that you replace the battery door on your PM5, even if you have not experienced any issues.
Additionally, any battery door marked “REV A” or “REV B” that does not have a foam pad should be replaced.
To request a free battery door replacement, please contact our customer service department directly.
In addition to replacing the battery door, we also suggest updating your PM5 to the latest version of firmware.
We apologize for any inconvenience you may have experienced related to this issue and hope that you contact us with any further concerns.
