Protecting ETERNITY NENX and Yourself
ETERNITY NENX is an electronic device. When you handle any electrical or electronic equipment, you are in a
situation that could cause you bodily harm, besides damage to the product. When handling any electronic
equipment, you must be aware of the safety hazards involved in electrical circuitry and the standard practices for
accident prevention.
Take every safety precaution to reduce the risk of fire, electric shock and injury to persons. Read and understand
the precautions, dos and don't s of handling this product listed below.
These instructions are by no means exhaustive. So, take all the necessary precautions for handling electronic and
electrical appliances. Your safety and that of the others lies in your hands.
Location
• Do not place this product in locations that are close to a water source, on movable or unstable surfaces,
near high frequency generating devices, and areas where it may be exposed to dust, direct sunlight, heat,
excessive cold or humidity, where shocks or vibration are frequent or strong.
• Do not leave cables exposed on the ground where they may be trampled upon, or get damaged by
entangling with feet or pressure from other heavy objects.
Power Supply
• This product should be operated with proper supply voltage. The DC Adapter (24VDC-2.5 Amp) provided
with ETERNITY NENX works with input voltage ranging between 100-240 VAC.
• Protect the system from heavy voltages from the mains.
• ETERNITY NENX has trunk and extension interfaces. So there are chances of heavy voltages entering the
system from trunk lines or from overhead extensions due to:
• Heavy voltage line falling on the CO line or on the overhead extension cables. A dangerous surge can
occur if a telephone line comes in contact with a power line.
• Lightning/Thunderbolts.
• Protect ETERNITY NENX from lightning and electrical surges by installing Primary Protection/Surge
Protectors on the trunk and long-distance or off-premise extension lines. The product warranty does not
cover damages resulting from lack of primary protection on trunk lines.
