The holder is fixed to the outside of the window pane using the supplied adhesive material. The thermometer can be inserted or removed without detaching the holder.

The MODE and "+" buttons allow the internal clock to be adjusted for the automatic reset function.

Important Operating and Safety Notes

• Avoid direct sunlight, which may distort readings and damage the LCD under prolonged or intense exposure.
• Heat transmitted through the window and building structure may result in readings higher than the actual temperature in an open, unsheltered location.
• Clean the window glass thoroughly before attaching the adhesive holder.
• Use the supplied plastic protective plate, especially in locations exposed to rain or strong sunlight.
• Do not bend or pull the delicate LCD when removing the thermometer or protective plate.
• Replace the battery when the display becomes weak, observing the correct polarity.
• Clean with a soft, slightly damp cloth. Do not use solvents or abrasive cleaning agents.
