Power
The lithium ion battery addendum supplies power to the real-time clock and CMOS memory
as an auxiliary source of power when the main power is shut off. Insert a coin cell battery into
the holder and make sure the polarities are correctly oriented — the cap side (rimmed rounded
edge) is negative and should be facing the holder; the flat side with a + mark is positive and
should be facing away from the holder.
Safety Measures
• There exists explosion hazard if the battery is incorrectly installed.
• Replace only with the same or equivalent type recommended by the manufacturer.
• Dispose of used batteries according to local ordinances.
