NOTE
The leak detector responds to all standard refrigerants. If you
use a different refrigerant to R-134a or R-1234yf, select the
R-134a mode.
Sensitivity level L and R-134a mode are preset.
If you use the leak detector in a heavily soiled area, press the
start button again after switching on. The device then switches
to a mode for heavily soiled areas. This is indicated by a low-
pitched beep which gets louder as soon as a leak is detected.
The device has four sensitivity levels with increasing sensitivity per
refrigerant (R-1234yf or R-134a):

➤ Press the start button (fig. 2 4, page 2) to select the sensitivity level or
to switch between the R-1234yf and R-134a modes.
