Battery Replacement
A 3V coin style lithium battery with part number CR2450N is installed in every ModSync screen. The battery is
responsible for the backup of the program, system data, and user settings. It is recommended that the battery be
replaced every 3-5 years to prevent issues such as loss of program or customer settings.
