Frequently Asked Questions - GBV 400-196 GUDE
How to replace the battery in my GUDE GBV 400-196 calculator?
To replace the battery, open the compartment on the back of the calculator with a small screwdriver. Remove the old battery and insert a new CR2032 battery, respecting the polarity. Close the compartment until it snaps shut.
