Switching the appliance on and off
W Switching on: Press the on/off button 3so that the tem- perature display lights up/flashes.
- When the appliance is switched on for the first time and while it is still warm, the display will contain dashes until the temperature falls below 0°C.
- The lighting will light up when the door is open.
W Switching off: Press the on/off button for approx. two seconds so that the temperature display goes out.
Setting the temperature
The appliance is pre-set for normal operation. We recommend a temperature of -18°C.
W To reduce the temperature:
Press the DOWN button 2.
W To increase the temperature:
Press the UP button 2.
-While you are entering the temperature, the set tempera ture will flash on the display.
-When you press the temperature setting buttons for the first time, the most recent setting (known as the "refer- ence setting") is displayed.
-You can change the settings in increments of 1°C by briefly pressing the buttons again. If the buttons are held down the temperature setting will change faster.
-The electronic controls will switch over automatically about
5 seconds after the last time you pressed the button, and the actual temperature in the freezer (known as the "ac- tual setting") will be displayed.
-The temperature can be set at between -14°C and -28°C.
Whether you can obtain the lowest temperature depends on where the appliance is positioned (if it is located in an area with a high ambient temperature it will not reach the lowest temperature).
Temperature display
The highest temperature of the frozen food 1 is dis- played in normal operating mode.
The display will flash:
- if you change the temperature or
- if the temperature rises by several degrees, indicating cold loss, e.g. if you place fresh, "warm" food in the freezer or if you remove or re-pack frozen food the temperature may rise for a short time due to warm air flowing into the freezer. Once you have finished loading or re-packing, the electron- ics will automatically re-set the temperature to the most recent setting. Short-term rises in temperature will not affect the frozen food.
W If "F 1" to "F 5" appears in the display, the appliance has a fault. Consult the customer service department indicat-ing the fault number displayed as this will tell the techni-cian what kind of irregularity has occurred.
Audible warning signal
The audible warning signal helps to protect frozen food and to save energy.
W The audible warning device is switched off by pressing GB the audible warning button 5.
- It switches off automatically as soon as the temperature is low enough or the door is closed.
Audible door alarm
- This sounds when the door has been left open for longer than about 60 seconds. The sound switch-off function is active as long as the door is left open. The alarm auto matically switches back to standby when the door is shut.
Audible/visual temperature alarm
- It always sounds if the freezer temperature is not low enough (dependent on the temperature setting).
- The temperature display flashes at the same time. This can be caused by:
- warm, fresh food being placed in the freezer,
- too much warm air from the outside entering when re-ar- ranging or removing frozen food.
The temperature display will continue to flash until the cause of the alarm has been rectified. It will then stop flashing and light up continually. The audible warning signal is now auto- matically reset.
Power failure/FrostControl display
If 
appears in the display, this means that the freez er temperature has risen too high during the last few hours or days due to a power failure.
W If you press the audible warning on/off button 5 whilst the display is reading 
, the highest temperature regis-tered during the power failure will be displayed.
- Check the quality of the food and its suitability for con- sumption in case it has become too warm or even de frosted.
- The highest temperature will appear for approx. 1 minute. After that, the actual temperature in the freezer will re-ap- pear. The display can be switched off by pressing the audible warning on/off button.
Once the power is re-instated, the appliance will continue to operate at the most recent temperature setting.
