Watson Duo Chargers

USB
You can use your Duo Charger to charge USB
devices while you're also charging your digital
camera or camcorder batteries.
1
Plug the USB end of the devices's charging
cable into the USB output jack on the side
of the Duo Charger. The USB output is
displayed on the LCD screen.
TEST BUTTON
You can test the charge state of your battery even
with the Duo Charger unplugged.
1
Just slide the battery into the charging plate
and press the TEST button.
2
Press the TEST button a second time to
display the voltage of the battery. After five
seconds, the display will revert to showing
the charge state.
3
If the charger does not charge the battery,
check to see if the battery is dead, faulty
or worn out. All rechargeable batteries
eventually wear out after being used for a
number of cycles.
