1. Precautions

1-4. Installation Precautions

For safety reasons, more than two people are required for carrying the product.

Keep the power cord away from any heat emitting devices, as a melted covering may cause fire or electric shock.

Do not place the product in areas with poor ventilation such as a bookshelf or closet. The increased internal 

temperature may cause fire.

Bend the external antenna cable when connecting it to the product. This is a measure to protect it from being exposed 

to moisture. Otherwise, it may cause a fire or electric shock.

Make sure to turn the power off and unplug the power cord from the outlet before repositioning the product. Also check 

the antenna cable or the external connectors if they are fully unplugged. Damage to the cord may cause fire or electric 

shock.

Keep the antenna far away from any high-voltage cables and install it firmly. Contact with the highvoltage cable or the 

antenna falling over may cause fire or electric shock.

When installing the product, leave enough space (10cm) between the product and the wall for ventilation purposes.  

A rise in temperature within the product may cause fire.
