NOTE
 The leak detector responds to all standard refrigerants. If you
use a different refrigerant to R134a or R1234yf, select the
R134a mode.
 Sensitivity level L and R134a 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 (R1234yf or R134a):

➤ Press the start button (fig. 2 4, page 2) to select the sensitivity level or
to switch between the R1234yf and R134a modes.
