Outside temperature indicator and digital clock
In addition to the time of day, the date and the outside temperature can also be called up. An hourly reminder signal can also be activated with the “MEMO” key.
The brightness of the display is controlled automatically, so that it is easy to read in poor light conditions.
When the ignition key is in position 0, the time and date can be called up by pressing the relevant function key. When the key is in position 1 or beyond, the time is shown. Values can be programmed in or changed.
Adjusting the time and date:
After an interruption in the power supply (first input, flashing dot) the time can be reset – without pressing the “HOUR” function key – at the two input keys “h/DAT” and “min/DAT”. To set the date, the function key “DATE” must first be pressed.
Each time the input key is pressed or after each half second that the key is held in, the value shown increases by one unit.
A symbol indicates the clock function and the letters “DAT” the date function.
Press the “HOUR” key to start the clock accurately to the nearest second and the “DATE” key to start the calendar program. The dot then stops flashing.
To make further changes to the settings, depress the re levant function key (“HOUR” or “Date”) until a f lashing dot appears between the hours and the minutes or the day and the month.
If the programm is not started after a new input, but an other function is selected, the old setting is retained.
Unrealistic inputs are not accepted by the program and zeroes preceding the figures are not shown. The date program does not include leap years and must therefore be corrected manually.
Notes on the 12-hour clock:
A fter the clock has run through the first 12 hours, it chan ges from AM to PM. This is indicated in front of the f igures. To meet various national requirements, the clock can be converted to a
12-hour, °F or a
12-hour, °C display
at a switch on the casing cover at the back. When the 24- hour program is switched over to a 12-hour program, the functions of the input keys change automatically from day and month to month and day.
The “MEMO” key is used to activate or deactivate an hourly reminder signal. The signal sounds 15 seconds before the beginning of each full hour and can be used to remind the driver to switch from cassette to radio opera tion for traf fic reports etc. When the signal is activated, the letters “ME” appear in the display.
When the “TEMP” key is pressed, the outside temperatu re is displayed. If the outside temperature falls below
+ 3°C with the ignition key in position 1 or beyond, a gong sounds to indicate the possibility of black ice on the road surface. At the same time the unit of measure ment (°C/°F) and the dot f lash for 10 seconds in the dis play.
If another function is selected and the temperature cal led up again during these ten seconds, only the visual warning signal f lashes for the rest of this period.
The temperature warning signal is repeated if the tempe rature has increased to + 6°C at least once since the last warning signal, and again dropped below + 3°C.
