1. Verify you are using fresh alkaline batteries or lithium batteries (when the temperature is below -4°F/-20°C) in the sensor.
2. Quality brand batteries are recommended, including Duracell, Rayovac and Energizer.
3. Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.
4. Generic or store brand batteries are not recommended for use with Klockit products because they may cause performance irregularities due to the way these types of batteries disperse power.
5. Rechargeable batteries are not recommended for use with Klockit products because they may cause performance irregularities due to the voltage instability of these types of batteries.
6. Mixing different battery types (brands, old/new, etc.) is not recommended.
