Generation and Prevention of Electric Blanket Static
After the electric blanket is powered on, some users will feel an electric short when their dry bodies slightly touch the
blanket. After their bodies cling to the blanket, they do not have such a feeling. This is called electric induction. When
the heating wire is powered on, an AC magnetic field is generated. Due to the AC magnetic field, electric charge is
gathered on the surface of the blanket. When our skin touches the blanket with static, electric charge is discharged.
Static is a natural phenomenon. Due to friction, underclothes made of chemical fiber, carpets, cushions and wall paper
will generate static. Home appliances will also generate static when they are being used.
The following methods of eliminating static are simple and easily used:
1. When indoor air humidity is less than 30%, static is easily generated. If humidity is increased to 45%, static is hard
to be generated. As a result, in dry weather, sprinkle water in the house or place one to two basins to hold water
at the places where sprinkling water is inapplicable to increase indoor air humidity.
2. Static particulates are generated around screens of TV sets and computers. These particulates will adsorb
floating dust and be absorbed on to our skins. As a result, wash your hands and face before going to sleep.
3. It is recommended that elders, children, and static-sensitive persons should wear underclothes completely made
of cotton in winter, and frequently bathe and change clothes to avoid influence of static.
4. Walk barefoot helps discharge of static on the body surface. As a result, walk barefoot before going to the bed,
which effectively eliminates static on the body surface.
5. On the electric blanket, bed sheets or bedspreads completely made of cotton are preferred.
5 Installation
The electric heating blanket should be laid on a relatively hard and nonadjustable mattress.
The blanket body should be laid flat from shoulder to feet when sleeping.
The electric heating blanket can be spread either on the front side or the back side. The side with the switch should be
placed near the shoulder for convenient operation.

• Only use as under blanket.
• Never apply the blanket unsupervised.
• For all-night use, set the switch to the lowest level (1 button) before sleeping in order to avoid the risk of
heatstroke or switch the blanket off.
• Prolonged use of the heating blanket at a high setting could lead to skin burns.
• Do not cover the blanket with any other cushions. The control switch should not be covered or placed on or
below the blanket while the unit is in operation.
• Do not sit on the heat blanket. Instead, lie down on the blanket.

become trapped or rucked.
• Do not use with other heating appliances.
WARNING - Risks of fire
• Do not activate the blanket when it is still packed in the box. Extensive heat can occur and cause fire.
• Do not place the heating blanket under inflammable objects, especially not under paper or curtains.
