Battery removal and replacement
Locate battery on the computer. Reference the product manual if it is not easily
located. On some of the dual slot SBCs, the top board may need to be removed
to make it easier to remove the battery. Once the battery is located, take a non-
conductive tool and push at the back of the battery holder. Gently apply
pressure in order to not break the socket. The battery should slide forward out
of the holder. Pressure can be alternated between the two sides to get the
battery to slide out of the socket. The battery should slide forward enough that
it could be removed from the socket. A new battery can be installed by sliding
it into the holder. Make sure to observe correct polarity.
+5VSTDBY
The RTC can be supplied by this voltage if there is no battery onboard. It is
located at VME-Connector P1 (P7301) pin B31.
Without an onboard battery it is recommended to use an external supply
connected to this input. This voltage supplies the real time clock and the CMOS
RAM for storing the BIOS Setup settings.
