3. Operating Instructions
3.1 Using the Probes
Insert the pointed end of the probe into the thickest part of the meat, avoiding bone or gristle. Ensure the probe is inserted up to the safety notch to protect internal components and ensure accurate readings of both internal meat temperature and ambient cooking temperature.

3.2 Booster Display
The booster unit features an LCD display that shows both the internal meat temperature and the ambient cooking temperature directly, without requiring the app. This allows for quick checks during cooking.

4. Maintenance
4.1 Cleaning the Probes
After each use, clean the probes thoroughly with warm, soapy water. Wipe them dry completely before storing. Do not immerse the entire probe in water; only the metal shaft is waterproof. Avoid harsh abrasive cleaners that could damage the probe's surface.
4.2 Cleaning the Booster
Wipe the booster unit with a damp cloth. Do not immerse the booster in water or expose it to excessive moisture. Ensure the charging ports are clean and dry.
4.3 Battery Care
The probes have a battery life of approximately 36 hours on a full charge, while the booster's battery can last up to 3 months. Recharge the devices as needed using the provided USB cable. Store the probes in the booster when not in use to keep them charged and protected.
5. Troubleshooting
5.1 Probe Not Connecting or Inaccurate Readings
- Ensure Full Charge: Verify both the probes and booster are fully charged.
- Proper Insertion: Make sure the probe is inserted correctly into the meat, past the safety notch.
- Bluetooth Range: Confirm the booster and your smartphone are within the 500ft Bluetooth range. Obstructions can reduce range.
- App Status: Check if the TempSpike app is open and running in the foreground or background on your smartphone.
- Reset: Try restarting the app or power cycling the booster.
5.2 Booster Display Issues
- Backlight: The LCD is backlit for visibility in low light. If the display is dim, ensure the booster is charged.
- No Reading: If no temperature is displayed, ensure probes are correctly inserted into the booster and meat.
