433MHz transmission and will result in higher power con-
sumption. Therefore batteries will have a shorter life span for
cable connection compared to using 433MHz.
To operate using cable connection, simply use the enclosed
10 meter cable and connect the thermo-hygro sensor to the
base station. Once the connection is detected, the base sta-
tion will automatically continue reading the data from the
sensor.
The user may at any time switch from cable connection to
using 433MHz (or vice versa) by simply disconnecting (or
connecting) the cable from the base station to the sensor.
When the base station detects no cable connection to the
sensors, the existing data reading interval is changed to the
new reading interval, i.e. using cable connection is every 8
seconds data reading interval or from 32 seconds - 128 sec-
onds intervals when using 433MHz (depending on wind
speed)
Using the AC adaptor to operate the base station will also
supply power to the sensor if the cable is connected to it.
Batteries used for 433MHz transmission may be left in the
sensor when using cable connection for power back-up in
case of AC power failure. A loss of power would desynchro-
nize the base station and the sensor and no weather data will
be received. To Synchronize the units so that the weather
data can be received, press and hold the PLUS(+) for 2 sec-
onds. However in general, batteries that will not be used for
long periods should be removed to avoid leakage.
Wireless 433MHz transmission:
Using 433MHz wireless transmission of weather data from the
sensor to the base station will provide users greater freedom
as to where units can be positioned without the need to be
restricted by cable.
Note:
If no outdoor weather data is displayed or the signal to the
sensors is lost during setting up, mounting, changing of batter-
ies to the sensor or plugging or unplugging cables, simply
press and hold the PLUS(+) key for 2 seconds and a short
beep will sound to synchronize the base station to sensors.
