- Install Sensor Batteries: Insert 2 AAA batteries into the remote sensor, ensuring correct polarity (+/-). Close the battery compartment.
- Install Main Unit Batteries: Open the battery compartment of the main display unit. Insert 2 AAA batteries, ensuring correct polarity (+/-). Close the battery compartment.
- Establish Connection: Place the main unit and the remote sensor close to each other (within a few feet). Allow 2-3 minutes for them to connect and synchronize. Do not move them during this initial connection phase.

For optimal wireless transmission, ensure the remote sensor is within 200ft/60m of the main unit in an open area. The remote sensor is IPX4 splash-proof, but it is recommended to place it in a shaded, protected area away from direct sunlight and heavy rain to prolong its lifespan and ensure accurate readings.

Maintenance
- Cleaning: To clean the units, wipe them with a soft, damp cloth. Do not soak the units in water or use abrasive cleaners.
- Battery Replacement: When the battery indicator appears on the display, replace the AAA batteries in both the main unit and the remote sensor. Ensure correct polarity.
- Storage: If storing the thermometer for an extended period, remove all batteries to prevent leakage and damage.
Troubleshooting
- No Display/Blank Screen:
- Check if batteries are installed correctly with proper polarity.
- Replace old or depleted batteries with new AAA batteries. - No Outdoor Reading/Dashes on Display:
- Ensure the remote sensor is within the 200ft/60m wireless range of the main unit.
- Check for obstructions between the sensor and the main unit (e.g., thick walls, large metal objects).
- Re-synchronize the units by removing batteries from both, setting the sensor channel, then reinserting batteries into the sensor first, followed by the main unit. Place them close together during synchronization. - Inaccurate Readings:
- Ensure both units are placed away from direct heat sources (sunlight, appliances) or cold drafts.
- Allow units to stabilize for at least 30 minutes after initial setup or relocation.
- For outdoor sensor, place it in a shaded, well-ventilated area, protected from direct weather elements. - Backlight Not Working:
- The backlight is designed to last 8 seconds per activation. If it doesn't light up, check battery levels.
