they lock into the housing (4).Now hook the positioning aid at the lower 
edge of the front cover (1) into the notches provided on the housing (4) 
and tilt the front cover (1) in the direction of the housing until it is locked 
at the top by the magnets on the housing (4).

2.  Place Roger/Roger little to the desired location on a flat surface, ideally 

centered in the room. This allows air to be supplied from all sides.

3.  Connect the mains cable (5) to its connection (6) on the unit and then to 

a suitable power outlet.

4.  Turn on Roger/Roger little by pressing the on/off button (7). The controls 

and the display light up in sequence from right to left. If no further but-
tons are pressed within 10 seconds, the display goes out again. Other-
wise, visibility is extended by a further 10 seconds. Pressing the on/off 
button (7) or the controls lights them back up. To turn Roger/Roger little 
off, press the on/off button (7) for two seconds.

5.  Air quality is measured by means of various sensors (Roger = gas and 

particle sensor PM2.5 / Roger little = gas sensor) and is indicated by the 
air quality indicator (8) on the front cover (1).The blue LED means good 
air quality. The orange LED shows medium air quality, and the red LED 
shows poor air quality. If the device is switched on again, the display will 
light up in orange for the first three minutes. The display then changes to 
the air quality currently measured (blue, orange or red).

6.  You can change the speed level by pressing the button for the selection 

of the speed level (9) (one LED for level 1, two LEDs for level 2, etc.). 
Increasing the speed level is useful when the air quality indicator (8) 
indicates decreasing air quality (blue for good air quality, orange for me-
dium air quality and red for poor air quality). For optimal air purification, 
we recommend activating auto mode (10).

7.  Pressing the button for auto mode (10) automatically adjusts the speed 

level to the current air quality (steps 1– 4). If the air quality deteriorates, 
the device automatically selects a higher speed level. The display shows 
“Auto” when auto mode is activated.

8.  By pressing the button for the timer (11) you can set the operating time 

for between one and seven hours (for example, 3 h = 1 h and 2 h LEDs lit, 
7 h = 1 h, 2 h and 4 h LEDs lit). The selected time is displayed above the 
timer button with white LEDs. Press once to set the operating time to 
1 h, press the button again for 2 h, and so on. The remaining time is indi-
cated by the illuminated LEDs above the timer button. The unit switches 
off automatically after the set operating time has elapsed. If no LEDs are 
lit above the timer, the unit is set to continuous operation.

9.  If you are bothered by the brightness of the LEDs and the air quality indi-

cator (in a bedroom, for example), you can reduce the luminous intensity 
by pressing the button for night mode (12). You can choose between 
three different modes:
•  Normal mode (default mode)
•  Dimmed mode (press once)
•  Lights-out mode (press twice). The controls cannot be switched off 

completely, but go out automatically after 10 seconds without input

Press the dimmer switch again to return to normal mode.

10.  Above the button for HEPA reset (13), four LEDs indicate the life span of 

the Dual Filter

TM

 (3). If all four LEDs are flashing, the Dual Filter

TM

 must
