Except for the fuse change and occasional cleaning, the function generator is maintenance-free. Use a clean,
lint-free, antistatic and dry cloth to clean the device. Do not use any abrasive or chemical agents or detergents
containing solvents.
Use a soft, clean and lint-free, anti-static and slightly moist cleaning cloth to clean the display.

If it is no longer possible to switch on the device, the mains fuse is probably defective.
Proceed as follows to replace the mains fuse:
• Switch off the function generator and remove all measuring lines and the mains cable from the device.
• Unlock the rear fuse holder (22) counter-clockwise with a suitable at screwdriver under slight pressure. The bayo-
net closure of the fuse holder unlocks. Take out the fuse holder.
• Replace the defective fuse with a new ne-wire fuse (5x20 mm) of the same type and rated current.
Different fuses are used, depending on mains voltage selection:
Mains voltage Fuse
230 V 50/60 Hz F250mA / 250 V (quick-acting)
115 V 50/60 Hz F500mA / 250 V (quick-acting)
• Push the fuse insert back into the fuse holder and lock it under slight pressure clockwise until it latches cleanly.
