Prism battery lock - How to save my batteries?

Both the Prism100 and Prism550 head torches come with a battery lock to prevent them from accidentaly getting turned on when packed. This means you'll hopefully never end up in that horrible situation where you take out your headtorch only to find the fresh batteries you put in last night are now completely flat.

To turn on the battery lock simply press and hold the power button on the torch. The light will flash twice to indicate that the lock is now on. To turn it off just press and hold down the power button again.
