When the OMNI-4000 is turned off, the electronic circuits for the date and time are powered by an independent
lithium battery with a life expectancy of 3 to 5 years. The battery must be replaced at the end of this period, or when a
drift in time or difficulty in memorizing the date is observed. Proceed as follows:
• Remove the battery pack
• Remove the cover protecting the sensors and remove the sensors
• Remove the second cover over the circuit board
• Remove the flat connector (keyboard-printer circuit board link)
• Remove the screws securing the circuit board
• Carefully remove the circuit board vertically. The lithium battery can now be seen. See Figure 3-15
• Remove the old and insert the new lithium battery: the connections are soldered. Do not attempt to recharge the
lithium battery.
• Replace the circuit board, the securing screws, the connector, the sensors, the two covers and put the battery pack
back in place.
