Power supply for the SU-2 Image Viewer
The SU-2 Image viewer uses either the provided AAA batteries or a compatible
charger as a source of power. When connected to a charger, the SU 2- Image
Viewer does not use the batteries. Therefore, the batteries can be left in the
device, even if they are rechargeable.
When using batteries as a power source, the SU-2 Image Viewer automatically
enters sleep mode after 10 minutes, if it is switched on, but not connected to a
Bluetooth device. When the batteries are running out of power, a low battery icon
is displayed on the TV screen and the SU-2 Image Viewer switches off after 3
minutes.
