Grounding Precaution
•Be aware that your device may cause or be affected by electromagnetic interference or radio frequency inter-
ference. Keep the device at a safe distance from other electronic devices, such as pacemakers, hearing aids,
or other medical equipment, to prevent potential interference.
•Avoid placing the device near or on top of audio equipment or televisions, as it may cause interference with
the reception or operation of these devices.
•Use only compatible accessories and attachments approved by the manufacturer. Using unauthorized or
incompatible accessories may cause malfunction, damage to the unit, or pose safety risks.
•Regularly check for software updates and install them to ensure your device stays up to date with the latest secu-
rity patches and bug fixes. This will help maintain the device’s performance, stability, and overall user experience.
•Keep the device and all its accessories out of the reach of children. Small parts may pose a choking hazard.
Additionally, improper use of the device by children could result in damage or injury.
•Recycle or dispose of the device, its accessories, and batteries according to local regulations. Electronic de-
vices and batteries should not be disposed of in regular household waste to prevent environmental harm.
•Be aware that in certain emergency situations, such as earthquakes, fires, or power outages, the device may
not function as expected. Always have alternative communication methods and emergency plans in place.
Proper grounding is crucial for the safe and effective operation of your device. To minimize the risk of electric
shock, equipment damage, or interference, please follow these grounding precautions:
•Ensure the device is connected to a grounded electrical outlet: The device should be connected to a properly
grounded, three-pronged electrical outlet. This will help to protect the device and users from potential elec-
trical hazards.
•Check the grounding of your entire system: All interconnected devices, such as antennas, cables, and other
equipment, should also be properly grounded. This helps prevent ground loops, which can cause interference
and degrade system performance.
•Use grounded cables and connectors: When connecting the device to other devices, use shielded cables and
connectors with proper grounding. This ensures that the entire signal path is grounded, reducing the potential
for interference, and improving overall system performance.
•Inspect grounding connections periodically: Regularly check all grounding connections for signs of wear,
damage, or corrosion. Loose or damaged grounding connections can compromise the safety and perfor-
mance of your DTV headend system.
•Consult a professional if in doubt: If you are unsure about the grounding of your system or require assistance
with grounding-related issues, consult a qualified technician or electrician. Proper grounding is essential for
the safe and effective operation of your device and the overall DTV headend system.
By taking these additional safety precautions into consideration, you can further ensure the safe and proper use
of your device.
Handling
•Do not insert fingers or objects into the unit’s openings.
•Never insert paper, metal, or other foreign objects into the unit’s openings. If foreign objects are suspected in-
side the unit, turn it off, unplug the mains cord, and contact the manufacturer’s technical support department.
•Refrain from stepping on or placing heavy objects on the unit. Gently handle all buttons, connectors, and
switches to avoid hardware damage.
