Power can be supplied from an external source such as a 5 V or 9 V power bank.
- Connect the external power supply to the USB Type-C port (10) of the riflescope.
- The riflescope switches to external power source, while built-in Battery Pack APS5 and removable Battery Pack APS2 (or APS3*) will gradually recharge.
- A rechargeable battery icon indicating a percentage of the battery life will appear in the status bar.
- When you turn off external power source, the riflescope switches over to the removable battery without turning off. When there is no removable battery or low power level the device switches to the built-in battery.
Attention! Charging Power Bank APS2 / APS3 / internal APS5 batteries at air temperatures below 0 °C can result in reduced battery life. When using external power, connect Power Bank to the switched-on riflescope, which have worked for several minutes.
