Programming the pressure alarm values
This function might not be accessible due to a configuration setting.
When the SELECT-key is pressed a few times, pressure alarm values are displayed:

- high pressure alarm: 300 bar for example.
To change the alarm value, follow these steps:
1) press PROG: the word "PROGRAM" will flash or a pass code will be requested,
2) use
► to select the digits and ▲ to increase that value,
3) confirm the new alarm value by pressing ENTER.

When a value was changed but ENTER has not been pressed yet, the change can still be
cancelled by waiting for 20 seconds or by pressing ENTER during three seconds.

Pressure alarm
When the actual pressure is outside the allowed range, an alarm message will be displayed
indicating the type of alarm: "LO PRESSURE", "HI PRESSURE".
The alarm is terminated automatically as soon as the pressure is within its range again.
•
Low-battery alarm
When the battery voltage drops, it must be replaced. At first "
battery low”" will flash, but as soon
as it is displayed continuously, the battery MUST be replaced shortly after!
The remaining lifetime after the first moment of indication is generally several days up to some
weeks. See paragraph 6.3 for further information on battery replacement.
