Important Safety Instructions

 

Caution:

 

Read these instructions:

 

Read and understand all safety and operating instructions before using the equipment. 
Keep these Instructions:

 

The safety instructions should be kept for future reference. 

 

Heed all Warnings: 

 

Follow all warnings and instructions marked on the equipment or in the user information. 

 

Avoid Attachments: 

 

Do not use tools or attachments that are not recommended, because they may be hazardous

 

Warning!:

 

• This equipment should be operated only from the included power supply. 
•  To remove power from the equipment safely, remove all power cords from the rear of the equipment, or the 

 

desktop power module (if detachable), or from the power source receptacle (wall plug). 

•  Power cords should be routed so that they are not likely to be stepped on or pinched by items placed upon or 

against them. 

•  Do not defeat the safety purpose of a polarized or grounding-type plug. A polarized plug has two blades with one 

wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the 
third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for 
replacement of the obsolete outlet.

• Unplug this apparatus during lightning storms or when unused for long periods of time.
•  Refer all servicing to qualified service personnel. There are no user-serviceable parts inside. To prevent the risk of 

shock, do not attempt to service this equipment yourself because opening or removing covers may expose you to 
dangerous voltage or other hazards. Contact your local Neets reseller or distributor.

•  If the equipment has slots or holes in the enclosure, these are provided to prevent overheating of sensitive 

 

components inside. These openings must never be blocked by other objects. 

• Do not use this equipment near water. 
•  To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture and objects filled 

with liquids.

•  Unplug the product before cleaning. Clean only with a dry cloth and not cleaning fluid or aerosols. Such products 

could enter the unit and cause damage, fire, or electric shock. Some substances may also mar the finish of the 
product.

FCC Class A Notice:

 

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 
15 of the FCC Rules. Operation is subject to the following two conditions: 

1. This device may not cause harmful interference. 
2.  This device must accept any interference received, including interference that may cause undesired operation.

 

The Class A limits are designed to provide reasonable protection against harmful interference when the 

 

equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio 
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful 
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful 
interference, in which case the user will be required to correct the interference at his own expense.

FCC regulations state that any unauthorized changes or modifications to this equipment, not expressly approved by 
the manufacturer, could void the user’s authority to operate this equipment.

The lightning bolt triangle is used to alert the user to the presence of uninsulated “dangerous 

 

voltages” within the unit’s chassis that may be of sufficient magnitude to constitute a risk of electric 
shock to humans.

The exclamation point triangle is used to alert the user to presence of important operating and 

 

service instructions in the literature accompanying the product.
