Monitor Gateway 2000

[Hans]

Have a Monitor,Gateway 2000 model CPD15F23,Vivitron15,manufactured by Sony.
I dont know if this monitor is for use with 110 VAC power or 220 V.
The label back says:100-110V-50/60Hz 1,8A *** 220-240 V-50/60 Hz 1 A. There is not any selector switch do select the input voltage.
Normally the monitors says: AC input 80 to 240 V.
This monitor was manufactured on 1996.
If any collegue have the electronic diagram,please help me.
Thank you in advance
Hans
