21 Symbols, display messages and troubleshooting
In addition to test results, the time and the date, your meter displays other symbols and error messages. Some of these routine
display messages have already been explained in earlier chapters. Following is a complete summary of all symbols and mes-
sages, what they mean and what actions you should take when they appear.
When you use the meter, pay close attention to all symbols and messages. Every symbol and every message provides you
with important information.
Therefore, if you do not know what a symbol means or do not understand a message, please refer to this chapter to find the
explanation. Otherwise you run the risk of wrongly interpreting your results.
Several symbols may appear at the same time.
For example, a combination such as test result, time and date with flashing thermometer,
drum, clock and bottle symbols may be displayed. This means that the temperature during
measurement was at the limit of the permitted range and that the 90-day use-by period for
the test strip drum had expired.
