Controls
- Power: turns the heater on and off
- Temperature: sets your target temperature, shown on the LED display
- Timer: sets an automatic shut-off
Troubleshooting
It won't turn on
Make sure it's fully plugged into a working wall outlet (not a power strip). Try another outlet.
It stopped heating
Overheat protection may have switched it off. Unplug it, let it cool for 10–15 minutes, make sure nothing blocks the grille, then plug it back in.
The room isn't warming
Close doors and windows and check your target temperature. It's built for smaller rooms.

Reading the display
The LED display shows the temperature setting and timer. Use the buttons on the heater to raise or lower the setting and to set how long it should run before switching off. Always follow the printed manual included in the box.
Safety reminders
Plug it straight into a wall outlet — never an extension cord or power strip — and keep about 3 feet of clear space in front of it.
Keep it away from water, bedding, curtains and paper, and unplug it when not in use.
Troubleshooting
- No power: check the outlet with another device and make sure the plug is fully inserted
- Switches off by itself: the timer or overheat protection may have activated — unplug, let it cool, and try again
- Not warm enough: use it in a smaller, closed room and place it near where you sit
How to set up Cyber Heater
- Choose an outlet: Pick a wall outlet with about 3 feet of clear space in front, away from curtains and bedding.
- Rotate the plug: Turn the 180° swivel plug so the heater sits upright on your outlet.
- Plug in: Push the heater directly into the wall outlet. Never use an extension cord or power strip.
- Set the temperature: Use the buttons to choose a comfortable temperature on the LED display.
- Set the timer: Set the timer so the heater switches off on its own.
