[. . . ] Put all radio sensors that you want to use into operation and place these in close proximity (1-2 metres) to the reception device. Open the battery compartment of the display device and remove all insulation strips. If no batteries are in the device, insert the 2 batteries (UM-3 or `AA' 1. 5 V) in the correct polarity. Directly after the activation of the batteries, all segments are displayed for a few seconds on the display. [. . . ] When the signal is interrupted, you can start a new signal search at any time manually. whether the sensor is still in place the batteries of the sensor and the display device. Please also replace them when a battery tester rates them as still being sufficient!Note: If the outdoor temperature drops sharply, the output of batteries that have been started is also strongly reduced. It is therefore recommended that new batteries are always inserted in the sensor at the beginning of the winter (alkaline type or better). whether disturbances or shields are to be found in the area of the sender/receiver or the distance between the two devices is too great. The search processes described above for a `lost' sensor do not have any influence on any other existing sensors that function without problems. Signal `collisions' Radio signals of other devices in their environment can cause disruptions or temporary interruptions in reception. Such typical 'disruptive systems' are radio door bells, wireless security systems, tube screens (PC/TV), control systems, etc. OPERATION 5. 1 TIME The time (hh:mm) and the date are depicted in the upper information window. -Time setting -----SET---- By pressing the CHANNEL/+ and MEMORY/- keys at the same time and holding them for approx. The element to be set starts flashing in the display: With the + and - keys, you can now make a setting for as long as the element is flashing. You can now move from setting to setting with a single brief pressing of the SET key. Important general information about the thermo/hygro alarm: - An alarm programmed on Channel 1 can only be triggered by the sensor 1. - The temperature alarm can be set in steps of 0. 5 ° C (0. 9° F), the hygro alarm in steps of 1%. - So as not to trigger any permanent alarm with minor changes around the alarm limits, the alarm trigger has a hysterisis of 0. 5° C (0. 9° F), respectively 1% r. H. if an alarm has been triggered, the new measurement value must fall under the alarm value by at least 0. 5° (0. 9° F), respectively 1% r. H. , to switch off the active alarm automatically. Example: An HI alarm at 24° first has to be set to inactive when it reaches 23. 5° C again. This prevents the measurement around a certain point triggering an alarm permanently. With simple thermo sensors you may set an alarm for the hygrometer, but this value will have no function. By all means, leave it active ­ should you deactivate the hygro alarm, you will also deactivate the thermo alarm !no sensor be available on Channel 4 or 5, lines appear there instead of a temperature and rel. When set for the first time, HI 30. 0 °C (HI 86. 0°F) will appear with a . The number in the triangle refers to the channel for which the alarm is active. [. . . ] - 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. - Please keep the user's manual and other documents delivered with the device stored carefully so that you can reference them at a later point if necessary. - Please also remember that old batteries should not be disposed of with household waste but should be handed in at the designated collection centres.
