Battery
Half of all warranty issues can be resolved with fresh battery of the appropriate
voltage.
We suggest name brand alkaline battery.
Initial Setup
1. Remove the mounting holder and transparent cover from the LCD.
2. Hold the white grips on the side of the LCD and carefully remove it from the white case.
Note: Do not touch the LCD directly.
3. Remove the plastic safety strip, preventing the battery from making contact. Insert the LR44
button cell battery with the +side facing up.
4. Remove the protective scratch guard from the LCD.
5. Set time and date (see program menu).
6. Slide the IN/OUT switch to select indoor or outdoor use.
7. Carefully put the LCD back into the white case (circuit board will face the back, buttons will
face the front).
8. Replace the transparent cover over the LCD. Press firmly to secure it to the white case.

Thermometer Factory Restart
1. Remove the battery for 15 minutes.
2. Press one of the buttons at least 20 times to clear all memory.
3. Insert a fresh battery into the thermometer.
4. Do not press buttons for 15 minutes.
Window Thermometer
Power requirements
1 LR44 button cell battery.
Set Time
1. Carefully remove LCD from the white case.
2. Hold the MODE button until the hours flash.
3. Press and release the + button to adjust the hours.
4. Press and release the MODE button and the minutes will flash.
5. Press and release the + button to adjust the minutes.
6. Press the MODE button to return to the temperature display.
Note: The time must be set for the Min/Max temperature to work properly. If you
do not exit the program menu, the display will stay in program mode and not show
the temperature.
Can I view temperature in Celsius?
This station reads in Fahrenheit only.
MIN/MAX Temperature
The station shows the high/low temperature for the past 24 hours.
•The minimum temperature automatically resets at 8:00 P.M.
•The maximum temperature automatically resets at 8:00 A.M.
•If the time is not set, the minimum and maximum temperatures will not reset at
the correct local time or may read dashes (---).
Dashes, OF.L or stuck Temperature
This is generally a power related issue.
Battery may be overpowered or underpowered. Remove battery from wireless
thermometer.
Press any button 20 times. Leave the thermometer unpowered for 1-2 hours.
Install fresh alkaline battery with correct polarity.
If the indoor temperature is still dashes or OF.L, the thermometer may need
replacement.

Mount on Window
Indoor Use:
1. Remove the window thermometer from the mounting holder.
2. Clean and dry the area to mount the window thermometer so the adhesive will
stick.
3. Remove the thin cover from the adhesive to reveal the sticky side.
4. Carefully place the mounting holder with the opening facing up.
5. Insert the window thermometer.
Outdoor Use:
1. Choose an outdoor window location that is fairly dry and shaded for accurate
readings.
2. Remove the window thermometer from the mounting holder.
3. Clean and dry the area to mount the window thermometer so the adhesive will
stick.
4. Remove the thin cover from the adhesive to reveal the sticky side.
5. Carefully place the mounting holder with the opening facing up.
6. Insert the window thermometer.
•Avoid direct sunshine, as it will cause false high temperature readings.
•Constant direct sunlight may fade the LCD, making it difficult to read.
•Due to the heat emission and sheltered location of your window, the
temperature may read higher with a window-mounted location then at a free
unsheltered location outside.
Remove from Window
The adhesive used to secure the thermometer is very strong and elastic. The best
way to remove the holder from the window is with a flat blade and patience.
Remove the window thermometer from the holder.
Gently slide a flat blade beneath one end of the holder. Lift slowly and gently
allowing the adhesive to slowly stretch and finally release from the window.
Repeat the process on the other side.
This takes several minutes to accomplish. Be careful not to damage the window.
New adhesive will be required to remount. Check in your local hardware store.
Accuracy
Since no window is a perfect insulator, it is possible that this temperature skew is
caused by heat leakage through the window pane.
To double-check the accuracy of the thermometer, remove it from the mounting
bracket (leave the bracket attached to the window), bring it indoors for two
hours, and set it next to the thermostat.
If it is within 2-3 degrees, the thermometer is working correctly. If the
temperature gap is greater than 3 degrees after 2 hours, the window
thermometer may be defective.
