Temperature. Avoid exposure below −20 °C or above +45 °C. Extreme temperatures reduce battery capacity, shorten battery life, and may degrade detector performance.

Moisture. Despite IP64 protection, avoid getting the device wet. Water ingress voids the manufacturer’s warranty. If water gets on the device, wipe it with a dry cloth.

Condensation. If the device has been brought in from the cold, leave it in its packaging at room temperature for two hours before opening. Otherwise, moisture condensation may cause a malfunction.

Handling. Do not grip the device tightly; press the buttons gently. Handle with care — the display can crack or get scratched.

Impacts. Drops and rough handling may cause serious damage to the device’s electronics.

EMI. Avoid strong electromagnetic fields and electrostatic discharge. Household electronics, cordless phones, and routers may interfere with the device.

Dust. Do not use or store the device in contaminated or dusty environments.

Heat. Avoid contact with hot objects and open flames. The battery may ignite if overheated.

Charging. Use only USB chargers rated at 5 V and at least 0.5 A, or a computer USB port. Do not use faulty chargers. Connect the USB cable carefully. Damage caused by improper charging is not covered by the manufacturer’s warranty.

Firmware update. Do not disconnect the device during a firmware update — interrupting the process may cause a malfunction that can be resolved by contacting the manufacturer’s support.

Radioactive contamination. Avoid contaminating the device with radioactive materials. When working in potentially contaminated areas, place the device in a sealed bag.
