Battery Charging
To charge the battery:
- plug the USB cable into the connector located at the end of the device ([14] in the general view);
- plug the USB cable into the connector of a computer or a special charger;
- Keep the device connected to the charging source until it is fully charged.
The charging process is indicated by the glowing blue indicator ([18] in the general view). If the device is turned on, the screen will display the icon ([3] in the general view). At the end of the charging procedure, the blue indicator will turn off, and the icon will change to indicate power supply from an external source.
Pay attention to the charge indicator icon while using the device. If the charge indicator is empty 
, then connect the device to the charger.
To ensure proper battery charging conditions and extend battery life, the dosimeter is designed to halt the battery charging process when the instrument's temperature exceeds +40°C or falls below 0°C.
To charge the device, use only chargers designed for USB devices with a voltage of 5V and a current of at least 0.5A, or a USB port of a computer. Connecting the device to an incorrect charging source may cause damage. Devices damaged due to incorrect charging are not covered by warranty repair.
Use only a direct USB connection to a dedicated power adapter or standalone USB port. Avoid USB hubs, shared charging stations, 3-in-1 or multi-device charging cables, and simultaneous charging of other devices from the same power source.
If the battery is completely discharged, the device may not respond when you try to turn it on. The battery must be recharged to start the dosimeter. If the battery does not charge, connect the charging cable, then disconnect and reconnect it. The device will then be ready for operation.
