The device supports both digital (HDMI) and analog (A/V) connections, ensuring compatibility with a wide range of equipment.
Usage Features:
The Set-Top Box offers versatile connectivity options to integrate seamlessly into your home entertainment setup. For optimal picture and audio quality, it is recommended to connect digital devices using an HDMI cable. The front panel of the device includes two HDMI input ports (HDMI IN 1, HDMI IN 2) and two USB input ports (USB IN 1, USB IN 2), along with dedicated ports for external MPI control and MPI/MTI Television Control. The rear panel provides a more comprehensive array of connections, including:

The manual emphasizes the importance of using certified HDMI cables (3 m or less) to avoid display or connection errors. It also advises on USB device compatibility, recommending USB hubs or HDDs with external power supplies if the device's power is insufficient.
For antenna or cable connections, the Set-Top Box supports VHF and UHF antennas, as well as coaxial cable inputs. It is important to ensure that the copper wire of the RF cable is not bent to maintain signal integrity. The device supports DTV Audio Codecs such as MPEG and Dolby Digital.
Optional accessories, such as rubber pads and Dual Lock™ strips, are provided to secure the Set-Top Box. The rubber pads can be attached to the bottom of the product to prevent sliding, especially if the device is placed on a flat surface. The Dual Lock™ strips allow the Set-Top Box to be securely attached to the back of a TV, utilizing VESA screw holes for a firm mounting. When using Dual Lock™ strips, it is crucial to ensure the product surface is clean and to allow the adhesive to dry for at least three days before attaching the Set-Top Box to the TV. The manual also mentions an optional Magic Remote (AN-MR18HA) for enhanced control.
The Set-Top Box supports a variety of media formats, including popular photo formats like JPEG, PNG, and BMP, and audio formats such as MP3, OGG, WMA, and FLAC. For video playback, it supports numerous extensions and codecs, including H.264/AVC, HEVC, MPEG-1/2/4, and Dolby Digital. It also supports external and embedded subtitles in various formats.
A key feature for enhanced visual quality is the HDMI Ultra HD Deep Color setting. When connected to a compatible input port, enabling this feature can result in clearer pictures by supporting 4K resolution at 60 Hz with various color sampling modes (4:4:4, 4:2:2, 4:2:0). If the connected device does not support Deep Color, the setting should be turned off to avoid display issues.
Maintenance Features:
Regular maintenance is crucial for the Set-Top Box's peak performance and extended lifespan. The manual provides clear instructions for cleaning the device:
- General Cleaning: For dust or light dirt, wipe the surface with a dry, clean, and soft cloth.
- Major Dirt: For more significant dirt, use a soft cloth dampened with clean water or a diluted mild detergent, then immediately wipe dry.
- AC/DC Adapter: Regularly remove accumulated dust or dirt from the adapter.
Important Cleaning Precautions:
- Always turn off the power and disconnect the power cord and all other cables before cleaning.
- If the Set-Top Box will be unattended or unused for a long time, disconnect the AC/DC adapter from the wall outlet to prevent damage from lightning or power surges.
- Avoid pushing, rubbing, or hitting the surface with fingernails or sharp objects to prevent scratches.
- Do not use chemicals such as waxes, benzene, alcohol, thinners, insecticides, air fresheners, or lubricants, as these can damage the product's finish and cause discoloration.
- Never spray liquid directly onto the surface, as water ingress can lead to fire, electric shock, or malfunction.
Troubleshooting:
The manual includes a troubleshooting section to address common issues:
- Remote Control Issues: If the remote control is not working, check for obstructions, ensure no tape is covering the receiver, and replace batteries with fresh ones.
- No Video or Audio Output: Verify that the product is turned on, the power cord is securely connected to a wall outlet, and test the wall outlet with other products.
- Sudden Power Off: Check power control settings, ensure the power supply is not interrupted, and verify if the auto-off feature is activated in the Time settings.
- "No Signal" or "Invalid Format" with PC (HDMI/DVI): Turn the Set-Top Box off/on using the remote, reconnect the HDMI/DVI cable, and restart the PC with the Set-Top Box on.
