Keypad light of Motorola SLVR?

I recently bought a Motorola SLVR from a friend. He told me when he got it, the keypad didn't light up. Most cell phones have an option where you can turn the keypad light on/off. I've looked through this phone so many times to try and find something about the keypad light so I can try to get it to work. I can't find a thing. Is this phone just messed up, does this phone just not have a keypad light, or...? I don't think that it doesn't have one. What do I do to get it to work?? Help, please!
