APPENDIX
Inserting New Software Chips For Software Updates
PHYSICALLY CHANGE YOUR SOFTWARE CHIP:
Tools Needed: 1 medium flat screwdriver.
1) First, remove the AC adaptor plug from the back of the trapKAT !
2) Find a smooth, clean, flat surface and place your trapKAT upside down on it, the jacks facing
away from you.
3) Remove back cover of the trapKAT (16 screws).
4) When the trapKAT is opened, you will see one large circuit board towards the back. On the
front right of the printed circuit board is a large chip with a white paper label that says
something like “trapKAT 4.5”. The chip with the white label is your Software Chip, the code
that runs your trapKAT - its Operating System. Before you take the old software chip out, note
how it is oriented in the socket. Specifically notice that the “notch” on the end of the chip is
away from you.
5) The chip is at the top end of the circuit board. To remove an old chip, you will use your flat
screwdriver. You will pry the chip out of its socket. Look at the Upgrade chip you received and
you will be able to tell what is the chip and what is the socket. You want to insert the
screwdriver between the chip and the socket so as to pry up the chip but not the socket. As you
start to pry up the chip insert the screwdriver further under the chip and pry up more, then insert
screwdriver even further and then pry up more until the chip comes out of the socket. Don’t be
scared - just pry a little bit and then push the screwdriver in further, until the chip is out. Take
your time, don’t be in a hurry. Make sure you insert the screwdriver between the chip and the
socket before you start to pry each time. (Instead of between the socket and the circuit board.)
6) After you have the chip out, place the new chip in its socket, being careful to orient it in the
same way that the old chip was (remember the “notch”?). Take a little care to align the legs of
the chip into the holes in the pins of the socket. Then push down evenly on the chip. It should
push down snugly into the socket. Visually check to see that none of the legs got squished and
are smashed under the chip.
7) Replace the back cover of your trapKAT and reinsert the 16 screws.
8) Turn your trapKAT back over, and reinsert the AC adaptor plug into the trapKAT. Now turn
your trapKAT back on. If the display is working, you are OK. If the display is not working then:
a) Remove the AC adaptor plug again.
b) Turn the trapKAT over again and remove the 16 screws.
c) Take the back cover off again.
d) Try reinserting the chip (don't get legs bent under the chip).
e) Put the back cover on, turn the trapKAT back over, reinsert the AC adaptor plug, and turn the
power back on.
f) If this still fails, put your OLD software back in and give us a call @ 413-594-5190. 9) After
you have had the new software in and used it for several days, please send the old chip back to
us. They are reusable.
