Protecting VISIONPRO and Yourself

VISIONPRO 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, do's and don'ts of handling this product.
These instructions are not 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 moveable 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 as mentioned in
• Protect the system from heavy voltages from the mains.
• VISIONPRO has trunk and station interfaces. So there are chances of heavy voltages entering the system
from trunk lines or from overhead stations due to:
• Heavy voltage line falling on the CO line or on the overhead station cables. A dangerous surge can
occur if a telephone line comes in contact with a power line.
• Lightning/Thunderbolts.
• Short-circuit of trunk lines or overhead station cables with electric cables.
• The power supply of VISIONPRO is designed on switch mode design and hence supports a wider range of
operating voltage. However to protect the system from abrupt changes in the input voltage, use of CVT
within range of 100VA or 150VA is recommended.
• Protect VISIONPRO from lightning and electrical surges by installing Primary Protection/Surge Protectors
on the trunk and long-distance or off-premise station lines. The product warranty does not cover damages
resulting from lack of primary protection on trunk lines. For details, refer
