board). To remove the existing chip, ground yourself by tap your
hand to the metal surface on the analyzer. Hold the IC chip with one
hand and unlock the socket with the other by pushing the end of the
lever away from the PC board. Pull the existing IC chip straight out of
the socket and set it aside in an ESD protected location.
To remove the upgrade IC chip from the packaging, tap your hand to
the metal case of the analyzer again. Remove the new IC chip from
ESD protected package.
To install the upgrade IC chip in the socket, locate the notch on the
chip and ensure that the notch is pointed down. Align the pins to the
socket openings and insert the IC chip in the socket. While pressing
on the IC chip push the locking lever to the locked position (toward
the PC board) to secure the IC chip in place.
IMPORTANT
Be sure the notch of the IC chip is pointed toward the bottom of the analyzer
and that all the pins are engaged into the socket.
