The Temperature Station's built in sensor automatically measures the temperature once the batteries are inserted. 66 MINIMUM AND RECORDINGS: Indoor sign MAXIMUM INDOOR TEMPERATURE Minimum icon Maximum icon 67 By pressing the "MIN/MAX/+" key, the current indoor and outdoor temperature will alternate between the minimum, maximum and current temperature recordings (also changes for outdoor temperature). Once a new indoor temperature high or low is reached, it will automatically set into the Temperature Station's memory. OUTDOOR TEMPERATURE READING : The outdoor temperature reading is displayed on the bottom line of the LCD, under the indoor temperature. The Temperature Station receives the outdoor temperature via 868 MHz frequency, if the batteries are inserted into the transmitter within the 2-1/2 minutes of the setting up time (See Setting up above). 68 Note : Should the outdoor temperature not be received within 2 minutes after inserting the batteries into a transmitter, then see "Checking 868 MHz reception" below. MINIMUM AND READING: Outdoor sign MAXIMUM OUTDOOR TEMPERATURE Maximum icon Minimum icon 69 By pressing the "MIN/MAX/+" key, the current indoor and outdoor temperature will alternate between the minimum, maximum and current temperature recordings. The time when the minimum and maximum outdoor temperature records were received will be also shown on the LCD blinking. Once a new outdoor temperature high or low is reached, it will automatically be set into the Temperature Station's memory. RESETTING THE MINIMUM AND MAXIMUM READINGS : User may reset the minimum and maximum temperature data to the current value by the following step : Press and hold the MIN/MAX/+ key for about 3 seconds to reset all the minimum/ maximum data of all channels and the indoor sensor to the 70 current values in a single action. OUTDOOR TEMPERATURE CHANNEL 1, 2, AND 3 If more than one transmitter is used, and to alternate between the temperature readings of transmitter 1, 2, and 3, simply press the "SET/CH" key. If the reading is from transmitter 1, then the identification number "1" will be displayed in the outdoor temperature section of the LCD. The same will apply to the next transmitter and so on. However, if only one transmitter is used, no identification number will be displayed on the LCD. 71 CHECKING FOR 868 MHz RECEPTION: In normal surroundings (for example away from interfering sources such as TV sets), the outdoor temperature can usually be easily received within 2-1/2 minutes. If the outdoor temperature is not displayed on the LCD after 2-1/2 minutes, then check the following : 1. 2. The distance of the units should be at least 1.5 - 2.0 meters away from interfering sources such as computer monitors or TV sets. Avoid placing the units onto or in the immediate proximity of metal doors, window frames or structures. 72 3. 4. 5. 6. Using other electrical products such as headphones and speakers that operate on the same signal (868 MHz) can prevent the transmission pick up. Neighbours using electrical products operating on the 868 MHz signal can also cause interference. In most severe cases, the reception is only possible once all other electrical products using the 868 MHz are switched off. Within thick concrete rooms such as basements and tower blocks, the 868 MHz signal can be weakened (avoid placing near metal frames and structures). Transmission can be affected by exposure to extreme temperature conditions. For example, if the weather has been extremely cold 73 (under -25ºC) for an extended period of time then the transmission signal may be weakened. (Please bears this in mind when positioning the transmitter). Note : If the outdoor temperature is still not received by the Temperature Station after checking the above list, all units should be reset. 74 POSITIONING TEMPERATURE STATION : The Temperature Station comes complete with a detachable stand that gives the option of table standing or wall mounting. To wall mount : 1. Fix a screw into the desired wall, leaving the head extended out by abo ...
