The weather forecast may not reflect the current situation necessarily. The "Sunny" icon implies clear weather at night. 11 12 15 3. The transmission is within range and path is clear of obstacles and interference. l) Transmission Collision Signals from other household devices, such as door bells, home security systems and entry controls, may interfere with those of this product and cause temporarily reception failure. This is normal and does not affect the general performance of the product. The transmission and reception of temperature readings will resume once the interference recedes. m) Heat Index The heat index is based on the temperature and humidity measurements of the channel 1 sensor. The heat index is an index that combines air temperature and dew point in an attempt to determine the human-perceived equivalent temperature -- how hot it feels, termed the "felt air temperature". The human body normally cools itself by perspiration, or sweating, which evaporates and carries heat away from the body. However, when the relative humidity is high the evaporation rate is reduced, so heat is removed from the body at a lower rate causing it to retain more heat than it would in dry air. Measurements have been taken based on subjective descriptions of how hot subjects feel for a given temperature and humidity, allowing an index to be made which corresponds a temperature and humidity combination to a higher temperature in dry air. The heat index contains average assumptions about the human body mass and height, clothing, and the wind speed. Category normal caution Heat Index (°C) < 27°C 27 ­ 32°C Level 7. CLOCK AND ALARM MODE Important: All operations described in here are to be made in the clock mode Accessing Clock and Alarm Mode From the main console unit: Press + or - until the clock icon beside the time/date display starts flashing. 7. 1 Time Function HOW TO SET THE RADIO CONTROLLED CLOCK 1. The clock will search the radio signal automatically (DCF77 from Germany). It takes about 3-10 minutes to finish this process. If you wish to disable the auto-reception feature, hold "+" for 2 seconds to disable it. To enable the auto-reception feature again, hold "+" for 2 seconds again to start the reception and the regular synchronisations. If the radio signal is received, the date & time will be set automatically and the radio control signal icon [ ] turns on. If the clock fails to receive the time signal, it will show the [ ] icon. If the time is not correct, you may set the time manually. [. . . ] Never use volatile substances such as benzene, thinner, cleansing agents in spray cans etc. . - When the device is not being used store it in a dry area and out of the reach of small children. - If the device is activated under extreme coldness it may occur that the display becomes illegible. As soon as it is returned to a warm environment the device will function normally. [. . . ]
