Lithium Memory Backup Battery
The memory backup battery is a 3.0 volt lithium battery which protects
against loss of the GX-94’s memory when the main batteries are dead
or removed. The memory backup battery typically lasts for 5 years.
Replace the memory backup battery every 5 years or if you notice that
the GX-94 is losing logged data when the main batteries are changed.
