CMOS Battery Issues

***Disclaimer: While this article will cover issues that are generally caused by a failing CMOS battery, it's important to keep in mind that the solution may potentially lie elsewhere. 

If you're dealing with the following issues, you may need to replace your CMOS battery:

• The recorder's date/time settings constantly reset, change or revert to a strange date such as 01/01/2000.
• The recorder consistently loses its configuration settings.
• The recorder continuously factory defaults after a reboot or power outage.
• The recorder will not accept the backdoor codes provided after filling out the Lost Recorder Password Form.

Replacing a CMOS Battery

The type of the CMOS battery depends on the unit. The easiest way to verify this is by opening up the recorder for a visual inspection. Some batteries can be replaced by hand while others are soldered onto the motherboard. In the case of soldering, we recommend calling our tech support line or email us in order to set up an RMA  so the replacement process can be taken care of in-house. As warranty may be voided due to damage of the machine, replacements of soldered on CMOS batteries should only be handled by professionals. 

If you are off-site and unable to physically access the recorder, you can call our tech support line or email us and we can set up an RMA to verify the correct part number. 

To set up an RMA for a CMOS battery replacement or specification check, our tech support line can be reached @ 866-997-9009, or email, [e-mail]. Please have the Serial Number of the recorder available.
