Battery status
In this menu, you can display the battery voltage numerically (in Volts) or as a bar display.
The battery ensures that the data in the database and the current time are retained.
When the battery voltage is represented as a percentage, a battery voltage of
≤ 2 V is equal
to 0%, and a voltage of ≥ 3 V to 100%.
The data is secure up to a battery voltage of 2 V.
●
If the battery voltage is ≤ 2.45 V, the message "Replace battery" is displayed in the status
bar.
●
If the battery voltage is ≤ 2.30 V, the system displa
ys the following message: "Warning:
weak battery".
●
If the battery voltage is ≤ 2 V, the system displays the following message: "Caution: The
battery is dead".
●
If the time and/or database are not available after the system has been switched off for a
prolonged period due to the voltage being too low, the loss is established by means of a
CRC check when the system is switched on again. This triggers a message instructing
the user to replace the battery and then load the database and/or set the time.
For instructions on how to change the battery, see "Maintenance and servicing".
