Safety Instructions

To prevent damage to your Datapath product or injury to personnel operating the equipment, please
read the following safety precautions prior to operation. These instructions should be made available to
all those who will use and operate Datapath products.

Power Supply

All Datapath products require a mains power supply. This power supply must be disconnected when

to exposed live wires.

Ventilation

All computer equipment should be located in a well ventilated area. All ventilation holes on the comput­er casing must be kept clear of any obstruction at all times. Failure to do so will result in the system over
heating and damaging your equipment.

in temperature and should be placed on a stable and solid work surface. Liquids (hot/cold drinks etc)
should not be placed near the equipment as spillage could cause serious damage.

Gas/Flammable Liquids

Electronic equipment should never be used in the presence of gas or any ammable liquid, doing so
could result in an explosion or serious re.

Smoke/Unusual Smells

Should you notice smoke or unusual smells being emitted from your computer, turn o and unplug the
system from the mains supply. The system should then be passed to a qualied technician for

inspection. Continued operation could result in personal injury and damage to property.

Maintenance

Maintenance should only be carried out by competent technicians, any Datapath plug-in cards that are
physically damaged should be returned to Datapath for repair using Datapath RMA procedures.
