It's komatsu PC 200-8Mo.
Maybe try describing the problem a little more. There's gotta be some Komatsu folks here that know what it means. So you key on, then the monitor displays that image and nothing else happens?
Thanks for reply. When I'm key switch on the sign is singing in the monitor and buzzer are beeping. The monitor function key didn't work and don't showing any another code or massage.
Thank you for your reply, Do not showing L03 or L04 only showing the symbol and alarm beeping not working monitor any busines.
The F5 button didn't working.
