What do the symbols on my Philips Nose Trimmer mean?

Some nose trimmer models (Image 1) come with an on/off switch button located directly on the handle. Slide the button up to turn the trimmer on, slide the button down to turn it off. 

Other models have an arrow indicator located on the handle. 
To switch the trimmer on, turn the battery compartment cover counterclockwise until the setting indicator (V) aligns with the “on” indication (I) (Image 2).
To switch the trimmer off, turn the battery compartment cover clockwise until the setting indicator (V) aligns with the off indication (O) (Image 3). 
 

Some nose trimmers operate on disposable batteries. Before attempting to insert or remove the batteries for your nose trimmer, make sure your hands and the device are dry. To replace the batteries, the battery compartment can easily be opened by aligning the indications of the symbols as instructed below.
