Charging External USB Devices (see figure D)

You can use the USB port on the battery adapter to increase the battery runtime of various battery-operated USB devices, e.g. mobile phones or MP3 players. This can also be done whilst the garment is being heated.

Ensure that your external USB device can be charged using the USB port on the battery adapter. Refer to the specifications related to this topic in "Technical Data".

Connect the charging cable of your USB device to the USB socket (11) on the battery adapter (2).

Press the activation button (12) for approx. three seconds. The connected USB device will be charged.

To save energy, the USB port is automatically deactivated after approx. 2 hours. If no charging cable is connected, the USB port is automatically deactivated after 30 seconds.
