Serial CPU Board
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 SC5-FESTIVAL.
However, some versions of SC5-FESTIVAL are delivered with a battery holder which makes it possible
for the user to replace the coin cell. Use a BR2032 cell as replacement part to ensure an extended
temperature range. Be careful when removing the old cell and inserting the new one.
For boards with a soldered battery 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.
