Auto switch-off
The ability
to automatically turn off the heater after a certain time.
Auto switch-off performs three main functions. Firstly, it provides safety: even if the user forgets to turn off the heating pad, it will not overheat and cause a fire. Secondly, the overheating of the user himself is thus prevented; this is especially convenient if the heating pad is used during sleep. Thirdly, auto switch-off allows you to avoid unnecessary power consumption.
Note that the response time and features of its adjustment may be different. So, in the simplest models, only one option is provided (for example, after 90 minutes), more advanced devices may have
several time settings or even the ability to set it yourself within a certain range.
Operating time
The operating time is the time until the device auto-shutdown. Therefore the time during which a sheet or blanket works on heating. There are models with an adjustable shutdown timer, which allows you to set the required time for the device to automatically turn off.
Washing
Washing method allowed for the product.
Modern heating pads can be designed for both
manual and
machine wash. Note that both of these terms are rather conditional. So, “manual” washing can be carried out both manually and in an activator-type machine (semi-automatic) and even in an automatic “washer” if it has a special manual/delicate washing programme. Machine washable items can also be washed by hand.
Note that both options may provide specific requirements for washing conditions — in particular, a temperature limit. Therefore, before washing the heating pad, you must carefully study the corresponding section of the instructions anyway.
