range
The transmission range of the radio signals between the outdoor sensor and the projection clock
is up to 30 m under optimum conditions.
This range specifications refer to the so-called “free-field range.”
However, this ideal arrangement (e.g. projection clock and outdoor sensor on a plain, even meadow
without trees, houses, etc.) never exists in practice.
Usually, the projection clock is placed inside a house and the outside sensor is placed e.g. under
a carport or at a window.
Due to the different influences on the radio transmission, no specific range can be guaranteed.
However, trouble-free operation is usually possible in a single family house. When the projection
clock doesn’t receive any data from the outdoor sensor (despite new batteries), reduce the dis-
tance between outdoor sensor and weather station, change the installation site.
The range can sometimes be limited considerably by:
-
Walls, concrete ceilings
-
Coated/vapour-deposited insulating glass panes, aluminium windows
-
Vehicles
-
Trees, bushes, earth, rocks
-
Proximity to metallic & conductive objects (e.g. heating elements)
-
Proximity to human bodies
-
Broadband interferences, e.g. in residential areas (DECT telephones, mobile phones, radio-
controlled headphones, radio-controlled speakers, other radio-controlled projection clocks,
babyphones etc.)
-
Proximity to electric motors, transformers, power supply units, computers
-
Proximity to mains sockets, network cables
-
Proximity to improperly shielded or uncovered operating computers or other electrical devices

d) snooze function (snooze)
If the alarm signal is emitted, press the “SNOOZE/LIGHT” (1) button on the upper side of the pro-
jection clock briefly. The relevant symbol “
1
” or “
2
” flashes.
The alarm signal is interrupted for approx. 5 minutes after which it starts again.
End the snooze function prematurely by pressing the “ALARM” (5) button briefly. The relevant
symbol “
1
” or “
2
” stops flashing.
e) stopping the alarm signal
When a signal is emitted at the set alarm time, it may be stopped by pressing the “ALARM” (5)
button briefly.
If no button is pressed, the alarm signal stops automatically after 2 minutes.
deleting maX/min Values
-
Briefly press the “MAX/MIN” (8) button to switch between the maximum values (the display
shows “MAX”), the minimum values (“MIN”) and the current measured values.
-
To delete the saved maximum and minimum values, hold the “MAX/MIN” (8) button pressed
for at least 3 seconds.
seleCting the sensor Channels
-
Briefly press the “
▲
” (6) button to switch between the three channels for the outdoor sensors.
The respective channel number is displayed on the left of the displayed measured values
of the outdoor sensor.
-
For all the channels to be displayed one after the other automatically (for 3 seconds each),
hold the “
▲
” (6) button pressed (approx. 3 seconds) till an audio signal is heard. Then, release
the button again.
To end the Automatic mode, press the “
▲
” (6) button briefly.
aCtiVating displaY light / projeCtion
Press the “SNOOZE/LIGHT” (1) button briefly to activate the display light for a few seconds, it then
goes off automatically again (in the battery mode, the projector is also activated briefly).
temperature trend indiCator
The projection clock displays the temperature trend via a graphical symbol just to the right of the
indoor and outdoor temperature respectively.
Rising temperature
Constant temperature
Falling temperature
Cleaning and maintenanCe
The product is maintenance-free for you; you should never dismantle it (except for inserting/
replacing the batteries as described in these operating instructions).
To clean the exterior of the projection clock, a dry, soft and clean cloth is sufficient.
Do not press too hard on the display of the projection clock, this may cause scratches or the dis-
play to malfunction; furthermore, the display might break.
Remove dust on the projection clock or projector lens with a long-haired, soft and clean brush
and a vacuum cleaner.
Use a slightly damp soft cloth to remove dirt from the outdoor sensor.
Do not use abrasive cleaning agents, cleaning alcohol or other chemical solutions, since these
could damage (discolouring) the housing or even impair operation .
