6.  Align  the  new  microcontroller  with  the  socket  (note  the 

polarity  markings  on  the  microcontroller,  the  socket,  and 

the  circuit  board).    Be  sure  all  pins  are  aligned  with  the 

socket, and press the chip firmly into place.

 

 

 

7.  Reinsert the batteries.  The unit should beep when the last 

battery is inserted, and the display should show the model 

and serial number, and then ask that date and time be set.  

If not, double-check that the polarity of the microcontroller 

and socket are the same, and that the the batteries were 

inserted properly. 

 

8.  Replace the display module back into the station enclo-

sure, reinsert and tighten the four Phillips head screws, 

and reconnect the sensor wires.
