Battery Charging

Thermion 2 thermal imaging riflescopes come with a built-in rechargeable lithium-ion Battery Pack APS3 and a removable rechargeable lithium-ion APS2 Battery Pack (APS2 and APS3 for XP50 model). The batteries should be charged before first use.

1. Open the microUSB cover (9) by turning it counter clockwise.
2. Attach the microUSB plug of the USB cable (16) to the microUSB socket (10) in the body of the riflescope.
3. Attach the second plug of the USB cable (16) to the USB port on the power adapter (17).
4. Plug the device into a 100–240 V power outlet (18).

Attention! When charging batteries via the microUSB connector (10) in the body casing of the riflescope, the built-in Battery Pack is the first to be charged. Once it is fully charged, the removeable Battery Pack begins charging. When the device is in use, power consumption occurs in reverse order.

The rechargeable lithium-ion APS2 and APS3* Battery Packs may be recharged using the APS** charger:

1. Fully insert the rechargeable Battery Pack (8) supplied with your device, or purchased separately, along the guide rail into the APS charger slot (13).
2. Point A on the battery and Point B on the charger should be aligned.
3. Two batteries* can be charged at the same time – a second slot is provided for this.
4. Attach the microUSB plug of the USB cable (16) to the socket (14) of the battery charger (13). 
5. Attach the second plug of the USB cable (16) to the USB port on the power adapter (17).
6. Plug the power adapter into a 100–240 V power outlet (18).

The LED indicator (15) will display the battery charge status:
