If you want to modify hardware or add optional RFM12B chip and/or IR receiver you will need to
open enclosure
Warning: Please be very careful with enclosure, as acrylic tabs can be broken off easily. Never
force your way, go slowly. If someone doesn’t go in, see if you have a wire in a way.
● Put soft cloth on a table so you don’t scratch clock’s face.
● Remove small screw holding maintenance door from the back
● Remove big Acorn shaped nuts from the front of the clock and remove long screws.
While removing them hold back and front of the clock with your hand so it doesn
’t
separate.
● Lift off face plate and front panel gently. It’s attached to the mainboard with ribbon cable
and IR receiver cable (if you have one installed).
● Unplug both from main board and put front panel aside. If you need to remove LED
display, simply unscrew 4 screws holding it, but remember which was it was oriented.
● Main board and power supply both attached to the back panel, but power supply also
attached to the side panel via power jack.
● Unscrew 4 screws holding side panels to the bottom panel.
● Nothing is attached to the maintenance door (left) panel so you can just take it out.
● Right panel is attached via speaker cable to main board and via power cable to power
supply.
● You can lift off remaining panels once you unplug all cables (i.e. button cable, light
sensor cable and speaker cable).
● At this point you should be able to access and remove main board easily, just unplug
power cable that
’s attached to the power supply and 3 wire temperature sensor cable
that goes under the board to the temperature sensor glued to the back panel.
● Buttons cannot be removed without first disordering/cutting wires. If you need to replace
a button (for example you want different color), carefully unsolder it, press tabs to
remove, insert your own button and solder it back.
