BATTERY HOLDER ASSEMBLY UPDATE FOR 'BRAIN GAME (MK112)' MINIKIT

Some of the brain game (MK112) minikits come with a new battery holder that does not match the instructions in the manual. To assemble the new battery holder, follow these simple steps:

1. Solder a piece of wire (+/- 10 cm.) to the "+" pole lip of the battery holder.
2. Mount the battery holder.
3. Solder the wire from the "+" pole of the battery holder to the "+" on the PCB.
4. Solder a piece of (jumper) wire connecting the "-" pole of the battery holder with the "-" pole on the PCB.
