[. . . ] 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. 3 seconds, it is possible to change to the time setting mode. 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. The procedure of the settings is as follows: - Date setting (year ---> month ---> day) - Time format: 24 hours or 12 hours (AM/PM) display - Time setting (Hour ---> Minute) You cannot directly interrupt the setting process. You then therefore go through the entire selection of settings with the SET key until the time of day reappears again after the minutes setting with the flashing `:' In the time. If you do not press a key in setting mode for more than 2 minutes, the settings made will be adopted and the time of day displayed. 5. 2 THERMOMETER WITH ALARM With regard to operation, the HT78 is in a 'sleep mode' when no key is pressed for more than 2 minutes. This status is then recognised by the fact that on the left-hand side of the display neither the symbol nor the number in the channel display is flashing. In such a case, the operation is activated by pressing one of the 3 keys. The corresponding symbol then flashes in the field to be operated ( or `CH' with corresponding number). The HT78 measures the temperature directly and also receives the measurements of up to a maximum of 5 IROX thermo radio sensors. Each sensor can be set to one of the channels 1-5 (resp. In the two information windows ) the temperature currently measured is displayed in °C (or °F). (radio sensors CH1. . . . 5 and The following operations can be made in this function: 5. 2. 1 Reading of the temperature from each channel Activate the CHANNEL key briefly to jump from channel to channel. The next channel is displayed with each press of the button and activated for other operations. The sequence of the activation is --> CH1 ---> CH2 --> CH3 --> CH4 --> CH5 --> --> CH1 --> etc This is independent of whether a radio sensor is available in the system or not. Note: The measurement is always depicted in the lower window; the channels 1-5 one after the other in the middle window. 5. 2. 2 MIN/MAX memory a) With the `MEMORY' key you can read the Max/Min memory of the active channel by pressing it briefly (flashing symbol or CH1 . . . . The corresponding MIN/MAX value is displayed together with the date and the time of the recording (`time stamp'). 4 seconds in the following sequence on the display: - Maximum (=highest) temperature `MAX' - Minimum (=lowest) temperature `MIN' - Back to display of the current measurement The sequence can also be made manually by pressing the MEMORY key. All values shown have been recorded since the last memory reset. If no data are available, lines appear. b) Reset of the MIN/MAX memory If you hold the CLEAR key pressed for approx. [. . . ] In order to avoid a surprising and unpleasant interruption to operations, the battery symbol appears in the two temperature windows with the corresponding channel. 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 only use new batteries and never mix old and new batteries. [. . . ]
