Onyx C8002 is a rugged and user-friendly computer system with a minimum of components that you need to be familiar with. It has a two position, locking switch that is operated by a key. The left position is the power OFF position, the right is power ON. You can remove the key when the switch is turned to the ON or OFF position.
This computer system is designed to operate in a normal office environment. More specifically, it requires either a 115 VAC, 60HZ, 5.0 amp line, or a 230 VAC, 50 HZ, 2.5 amp line. The line must be grounded and unaffected by power surges. Temperature and humidity need not be specially controlled, although extremes should be avoided. Conditions suitable for normal office work are generally acceptable.

Onyx C8002 is a rugged and user-friendly computer system with a minimum of components that you need to be familiar with. It has a two position, locking switch that is operated by a key. The left position is the power OFF position, the right is power ON. You can remove the key when the switch is turned to the ON or OFF position.
This computer system is designed to operate in a normal office environment. More specifically, it requires either a 115 VAC, 60HZ, 5.0 amp line, or a 230 VAC, 50 HZ, 2.5 amp line. The line must be grounded and unaffected by power surges. Temperature and humidity need not be specially controlled, although extremes should be avoided. Conditions suitable for normal office work are generally acceptable.
