– For the best data reception quality of the
main unit try different positions of the main
unit or the external sensor and try chang-
ing the data reception and transmission
channels.
Note: - interference from professional or
household electrical appliances such as
doorbells, home security / alarm systems,
incoming control systems, radiotelephones,
walkie-talkies, games, computers and other
sources of interference may lead to tempo-
rary or permanent disturbances in receiv-
ing signals by the main unit, this does not
affect the main technical characteristics of
the unit, in some cases, the main unit or the
external sensor should be moved to another
location, free from the above said or other
obstacles preventing the passage of signals
from the sensor.
– When the external sensor (10) is transmit-
ting data, the indicator (13) lights up.
Main unit (1)
– Open the battery compartment lid
(9) and install two AAA batteries (not
included), strictly following the polarity.
You will hear a short sound signal. Then
install the battery compartment lid (9)
back to its place.
Notes:
– After the batteries are installed, the main
unit (1) links to the external sensor (10),
and the data reception activity indicator
«
» (30) starts continuously flashing.
After the main unit (1) links to the external
sensor (10), the outside temperature (28)
and relative humidity (27) will appear on
the display.
– The time required by the main unit (1) to
link to the external sensor (10) depends
on the conditions of data transfer by the
sensor (10) and on the conditions of
reception by the main unit (1), and it does
not exceed two minutes.
– In order to select or change the num-
ber of the data reception channel by the
main unit (1), tap the «
» button (4), the
respective data reception channel num-
bers (29) «CH1, CH2, CH3», and the con-
secutive display indicator (25) «
» will
appear on the display.
– Set the data reception channel number
corresponding to the data reception chan-
nel on the external sensor (10), to do this
open the battery compartment lid (11),
remove the batteries and set the data
reception channel corresponding to the
data reception channel on the main unit
(1) with the tuner (14).
– To search for and link the external sensor
(10) to the main unit (1)press and hold the
button «
» (4) for at least 3 seconds, until
display shows the flashing data reception
indicator «
» (30), after the main unit (1)
links to the external sensor (10), the out-
side temperature (28) and relative humidity
(27) will appear on the display.
Notes:
– If there are several external sensors,
set a different data reception channel
number on each of them, and select the
consecutive channel display mode on the
main unit (1). To select the consecutive
channel display mode tap the «
» (4),
until the display shows the consecutive
channel display indicator «
» (25).
– The indoor or outside temperature and
relative humidity indicators display the lower
limit as «LL» and upper limits as «HH».
Current time and date setting
– Press and hold the «
» button (8) for
at least 3 seconds - the display (1) will
show flashing numerical indication of the
«year» (21). Use the «
» (6) and «
»
(7) buttons to set the current «year». Press
the «
» (8) button to confirm the set-
ting. Flashing date format indication (24)
«MONTH» and «DATE» will appear on the
display.
Notes:
– if the buttons «
» (6), «
» (7), «
» (8)
are not pressed during 8 seconds during
the installation, the unit will revert to the
initial settings.
– to speed up the installation process press
and hold the «
» (6) or «
» (7) buttons
for at least 3 seconds.
