My IQ series instrument sometimes shows funny max values, e.g. a maximum altitude of 12000 meters.
Answer:
How this problem occurs:
The altitude is adjusted by pressing the arrow keys in such a way that the arrow key is pressed repeatedly within a short period of time to adjust single meter increments. (You could hold down on the arrow key to make the meters quickly count up or down, in this case the problem cannot occur)
If you press the keys repeatedly within a short period of time it can happen that suddenly the altitude jumps to a strange value (e.g. 12000 meters). If you press again the altitude jumps back to the correct value. No problem, but the strange value is stored.
What can you do to correct this problem:
At the moment there are two ways of getting around this behaviour:
If the strange value has shown, just switch off the instrument and switch it back on - the incorrect value will NOT be stored.
Do not press the arrow keys repeatedly within a short period of time but rather press the arrow keys for a longer period of time to start scrolling.
It seems this behaviour only shows in very rare instances.
