User manual IROX JKTG-4R

[. . . ] They contain some useful and interesting information that go beyond a mere explanation of how to operate the device. Radio channels 1-5: - current measurement of the selected channel (=radio probe) - memory values min/max of the selected channel - battery status of the sender displayed Full-segment display Comfort Zone: - display of the comfort status of the measurement of the indoor thermo/hygrometer Indoor thermo/hygro : - temperature and relative air humidity of the display device (measures at the location where the device is used) - memory values min/max of the indoor thermo/hygrometer - battery status of the display device 29 30 2. 2 KEYS / SWITCH / BATTERY COMPARTMENT Rear view T/H SET - For the IN measurement, the MIN/MAX values of the temperature or the relative air humidity are displayed below the current value. With this key, you can have the temperature or hygro memory displayed. MIN-MAX The MIN/MAX memory is managed and recorded depending on the setting. [. . . ] 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. The JKTG-4R then begins with the search of available sensors on all 5 channels. As soon as the sensor is displayed correctly (see `Reception status' in Chap. , 4), you can set up the sensor in the place where you want to effectively measure the outdoor temperature. In the event of problems, try out other places, and do so both for the sensor and for the display device. Nevertheless, please place the sensor where possible in the dry and at any rate in the shade. If you would like to display further sensors on the reception device, you can purchase these from shops. If you would like to display other interior spaces, the sensor JKR-1 from the `Instruments by Jörg Kachelmann' range is available in the same design as that of the display device and also has a large display. Reception status display The wave symbol indicates the status of the signal reception of the channel displayed. No signals. 33 34 Start search process for a sensor Select the desired radio channel with the CHANNEL key. Example: Channel 4 (the number 4 is flashing) 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. In such cases, it can also be helpful to use another channel. Now press and hold the SEARCH key until the wave symbol starts to flash. This process can take a few minutes and is finished as soon as the wave symbol stops flashing. We have deliberately ensured that the search channel can be individually called up per channel so that sensors that are already logged in are not affected by subsequent enhancements. 5. OPERATION 5. 1 THERMO/HYGROMETER The JKTG-4R measures the temperature and relative air humidity directly and also receives the measurements of up to a maximum of 5 IROX radio temperature sensors. Each sensor is to be set to one of the channels 1-5 (resp. 1-3 for 3-channel devices). [. . . ] This means that batteries of the display appliance (in the IN window) or of a radio sender (in the CHx window) are becoming too weak and need to be replaced. To change the batteries, please note Chapter 3 (Putting into operation). Please also remember that used batteries should not be thrown in the household rubbish bin but handed in at the designated collection points. [. . . ]
