How do I safely replace the oven light bulb?

First, disconnect power from the mains outlet or switch off the circuit breaker of the unit's mains outlet. Then unscrew the covering glass, replace the bulb with a new one of the same type (240V~25W high temperature resistant), and screw the covering glass back in place. Always ensure the appliance is switched off before replacing the oven lamp to avoid the possibility of electric shock. (Page 6)
