Setting up / operation
1. Remove the textile pre-filter (1) by taking hold of the top on both sides
and pulling it forwards. Take the Dual Filter
remove the plastic film. Set the Dual Filter
textile tabs are visible on the front side. Arrows on the top of the filter
(2) indicate the direction in which the filter must be inserted. Important:
Roger big has a textile pre-filter on both sides and a Dual Filter
fore both Dual Filter
2. Refit the textile pre-filter (1) by inserting the positioning aids near the
bottom of the textile pre-filter (1) into the notches on the housing (3) and
then tilting the textile pre-filter (1) towards the housing until it is locked
into place at the top by the magnets on the housing (3). Make sure that
the LED cylinder at the front towards the bottom of the appliance is
inserted in the hole on the pre-filter.
3. Place Roger/Roger little / Roger big to the desired location on a flat
surface, ideally centered in the room. This allows air to be supplied from
all sides.
4. Connect the mains cable (4) to its connection (5) on the unit and then to
a suitable power outlet.
5. Turn on Roger/Roger little/ Roger big by pressing the on/off button (7).
The controls and the display light up in sequence from right to left. If
no further buttons are pressed within 10 seconds, the display goes out
again. Otherwise, visibility is extended by a further 10 seconds. Pressing
the on/off button (6) or the controls lights them back up. To turn Roger/
Roger little / Roger big off, press the on/off button (6) for two seconds.
6. Air quality is measured by means of various sensors (Roger / Roger big
= gas and particle sensor PM2.5 / Roger little = gas sensor) and is indi-
cated by the air quality indicator (7) in front of the textile pre-filter (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).
7. You can change the speed level by pressing the button for the selection
of the speed level (8) (one LED for level 1, two LEDs for level 2, etc.).
Increasing the speed level is useful when the air quality indicator (7)
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 (9).
8. Pressing the button for auto mode (9) 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.
9. By pressing the button for the timer (10) 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.
s must be unpacked and inserted.
