Parameter menu
It is possible to set different parameter values in a parameter
menu. The parameter menu is accessed by simultaneously hol-
ding the INCREASE and DECREASE buttons depressed for about
5 seconds and then pressing the INCREASE button twice. The
Service indication will be displayed.
The display will initially show the parameter number “1”. Use the
INCREASE and DECREASE buttons to scroll between parameters.
Press the Occupancy button to select the desired parameter. The
parameter number will be replaced by the parameter value. The
value can be changed using the INCREASE and DECREASE but-
tons. If a button is held depressed the value will start scrolling,
rst slowly and then with increasing speed in 3 – 4 steps with 2
– 3 seconds between steps.
Acknowledge/Regret
To acknowledge and store a set parameter value, press the
Occupancy button again, the display then returns to showing the
parameter number. To retrieve the original value, i.e. the value
before change, press the INCREASE and DECREASE buttons at the
same time. The original value is shown on the display.
Return
After a certain time, about 1 minute, or when the INCREASE and
DECREASE buttons are pressed at the same time while in the
menu, the display returns to the normal view. Exit is shown on
the display after the last parameter. The parameter menu is exi-
ted by pressing the Occupancy button while in Exit. Pressing on
INCREASE goes to the rst parameter and pressing on DECREASE
goes to the last parameter.
