How to choose the suitable Anti Fog Belt?
- First, measure the circumference of the equipment where the anti-fog belt needs to be installed, or measure the diameter and multiply it by 3.14.
- Second, compare the obtained length with the length of the heated part(black color area) of the anti-fog belt and choose one that is close.

Using Instruction:
1. Press the power button to turn on the thermostat.
2. First, set the time (the default heating time for the first startup is 1 hour), press the timer button, set the heating time (1-12 hours), wait for about 5 seconds, and the heating time number on the display will start flashing. The flashing number indicates that the set time has been determined.
3. Press the heating/cooling button to enter the temperature setting interface, and select the appropriate heating temperature.
4. To change the set time midway, simply press the timer button, reset the heating time, wait for the number to flash (indicating that the set time has been determined), and then press the temperature increase/decrease button to return to the temperature interface.
- Note: In the presence of temperature differences, the actual temperature that can be reached by heating will be slightly lower than the set temperature.

Reminder:
- If you want a large aperture telescope to connect to a heating strap (such as 14 inches, 16 inches, or even 20 inches), you can buy two heating straps, each powered and heated. It does not affect each other and there is no heating blind spot (requires 2 power supply interfaces), making it very convenient for remote stations or places with on-board power supplies. You can calculate which models need to be connected based on the circumference of the telescope tube and the heating length of the heating strap (the sum of the heating parts of the two heating straps is approximately equal to the circumference of the tube). If there is power supply, three or more can be connected.
