Replacement of Battery 
The lithium battery on the MPB Board (24P0015) stores data while the power is 
turned off, and its life is about five years. When the voltage of the battery goes 
below a certain level, the message BACKUP ERROR appears when turning on 
the power. When this occurs, contact a FURUNO agent or dealer to request 
replacement of the battery, at your earliest convenience.   
The battery stores own ship’s static data and setting data, except MMSI no., 
IMO no., ship name, call sign, internal GPS antenna position, external GPS 
antenna position, type of ship, baud rate of each interface port, L/R mode, 
status of L/R port, AD-10 setting, and LAN port setting (These are stored in the 
involatile memory). After the battery has been replaced, reenter necessary 
data.
