Replacement of the Battery
When your system is turned off, a battery maintains the voltage to run the time-of-day clock and to
keep the values in the CMOS RAM. The battery should last during the lifetime of the PC3-ALLEGRO.
For replacement, the old battery must be desoldered, and the new one soldered. We suggest that you
send back the board to EKF for battery replacement.
Warning
Danger of explosion if the battery is incorrectly replaced or shorted. Replace only with
the same or equivalent type. Do not expose a battery to fire.
