Backup battery replacement


All systems returned to Chime Master for any reason receive the latest firmware updates and also a battery test. If the battery is low or more than five years old, we replace it.

Replacement by qualified technicians

The battery is replaceable by any qualified technician. Ideally replacement should be made while the system is turned off and unplugged, but that would require re-programming all settings in the system. Extreme caution should be exercised by qualified technicians replacing the battery in a powered system.

Systems with a USB port can have their settings backed up to a PC using the free Management Suite software Backup feature.

Battery type and location

The battery is a standard lithium coin battery type BR-2032 available at most department stores and pharmacies. It is installed in a battery clip on the main control PCB in the system.
