16 K2 Summit 3G Service Manual 14 November 2012
Safety Summaries

Use correct voltage setting — If this product lacks auto-ranging power supplies, before applying
power ensure that the each power supply is set to match the power source.
Provide proper ventilation — To prevent product overheating, provide equipment ventilation in
accordance with installation instructions.
Use anti-static procedures — Static sensitive components are present which may be damaged by
electrostatic discharge. Use anti-static procedures, equipment and surfaces during servicing.
Do not operate with suspected equipment failure — If you suspect product damage or equipment
failure, have the equipment inspected by qualied service personnel.
Ensure mains disconnect — If mains switch is not provided, the power cord(s) of this equipment
provide the means of disconnection. The socket outlet must be installed near the equipment and
must be easily accessible. Verify that all mains power is disconnected before installing or removing
power supplies and/or options.
Route cable properly — Route power cords and other cables so that they ar not likely to be damaged.
Properly support heavy cable bundles to avoid connector damage.
Use correct power supply cords — Power cords for this equipment, if provided, meet all North
American electrical codes. Operation of this equipment at voltages exceeding 130 VAC requires
power supply cords which comply with NEMA congurations. International power cords, if provided,
have the approval of the country of use.
Use correct replacement battery — This product may contain batteries. To reduce the risk of explosion,
check polarity and replace only with the same or equivalent type recommended by manufacturer.
Dispose of used batteries according to the manufacturer’s instructions.
Troubleshoot only to board level — Circuit boards in this product are densely populated with surface
mount technology (SMT) components and application specic integrated circuits (ASICS). As a
result, circuit board repair at the component level is very difcult in the eld, if not impossible. For
warranty compliance, do not troubleshoot systems beyond the board level.
