User guide

The ROM can quickly and simply be fitted using only a screwdriver, but when handling
the ROM care must be taken to isolate it from sources of static electricity (e.g: synthetic
clothing, carpets etc.). Take care to touch some earthed surface before removing the ROM
from its protective anti-static foam, and always handle the chip by holding the ENDS, refrain
from touching the pins unnecessarily: The fitting procedure is quite straightforward, but if you
are not confident about fitting the ROM then consult your dealer.
