SUBJECT Clock Board Installation Instructions
PRODUCT FAMILY WatchDog 2000 Series Weather Stations
DETAILS
Important: The clock board alone draws about
1/3 the power of the original station, so
Alkaline batteries can be expected to last 8-9
months. Use Lithium batteries ("Ultra" or
"High Energy") to obtain 12 month battery life.
1. Examine the clock board carefully to ensure
the battery is in the socket and there are no
bent pins .
2. Disconnect all sensor wires on the bottom of
the Weather Station display module.
3. Remove the 4 Phillips head screws on the
front of the module.
4. Pull the module straight out of the station
enclosure (may require light prying or
manipulation.
5. Remove the battery
cover, and remove all
batteries.
6. Flip over the display
module and locate the
microcontroller chip in its
socket. With a small
screwdriver or flat blade,
gently pry the chip out of
the socket by alternating
ends. Grasp the
microcontroller by the
ends of the black plastic,
not the pins.

circuit board. Note that the board extends up, not down
(see top image). Be sure all pins are aligned with the
socket, and press the board firmly into place (center
image).
8. Reinsert the batteries. Important: The clock board
draws about 1/3 the power of the original station, so
Alkaline batteries can be expected to last 8-9
months. Use Lithium batteries ("Ultra" or "High
Energy") to obtain 12 month battery life. The unit
should beep when the last battery is inserted, and the
display should show the model and serial number, and
then either show the date and time, or ask that they be
set. If not, double-check that the clock board and the
batteries were inserted properly.
9. Carefully check the date and time displayed on the LCD.
If necessary, reset the date and time:
