• Battery Replacement: Replace batteries in both the main unit and transmitter when the low battery indicator appears on the display. For optimal performance, it is recommended to replace both sets of batteries at the same time.
• Outdoor Transmitter Protection: While the transmitter is designed for outdoor use, placing it in a sheltered area will protect it from extreme weather conditions and extend its operational life.

Troubleshooting

• No Outdoor Temperature Display / Inaccurate Readings:
  • Ensure both units have fresh batteries and are inserted with correct polarity.
  • Verify that the outdoor transmitter is within the 100-meter (330-foot) range of the main unit and that there are no major obstacles (e.g., thick walls, large metal objects) blocking the wireless signal.
  • Try repositioning the outdoor transmitter closer to the main unit or in a different location.
  • Remove batteries from both units, wait for a few minutes, then reinsert them to force a resynchronization.
• Inaccurate Indoor Temperature:
  • Ensure the main unit is not placed near heat sources (e.g., direct sunlight, heating vents, appliances) or in areas with cold drafts.
• Display is Faint or Blank:
  • Replace batteries in the affected unit.
• Time Not Set Correctly:
