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
PC7-FESTIVAL.
However, some versions of PC7-FESTIVAL are delivered with a battery holder which makes it
possible for the user to replace the coin cell. Use a CR2032 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.
