MAINTENANCE

Cleaning Your Set-Top Box

Clean your Set-Top Box regularly to keep it at peak performance and to extend the product's lifespan.
To remove dust or light dirt, wipe the surface with a dry, clean, and soft cloth.
To remove major dirt, wipe the surface with a soft cloth dampened in clean water or a diluted mild
detergent. Then wipe immediately with a dry cloth.
Remove the accumulated dust or dirt on the AC/DC adapter regularly.
CAUTION
• Before cleaning, turn the power off and disconnect the power cord and all other cables.
• When the Set-Top Box is left unattended or unused for a long time, disconnect the AC/DC adapter
from the wall outlet to prevent possible damage from lightning or power surges.
• Do not push, rub, or hit the surface with your fingernail or a sharp object, as this may result in
scratches on the product cover.
• Do not use any chemicals, such as waxes, benzene, alcohol, thinners, insecticides, air fresheners, or
lubricants, as these may damage the product's finish and cause discoloration.
• Do not spray liquid onto the surface. If water enters the Set-Top Box, it may result in fire, electric
shock, or malfunction.
