1)  Insert  two AAA  batteries  into  the  remote  sensor. After  the  remote 

sensor is powered up, the sensor will transmit weather data every 8s 
for 16 times. After this learning period is over, then the transmitter will 
transmit every 48s.

2)  Insert  two AA  batteries  into  the  weather  station.  When  the  base 

station is powered up, a short beep will sound and all LCD segments 
will  light  up  for  about  4  seconds  before  it  enters  into  learning  mode 
to  learn  the  sensors  security  code.  Every  time  the  remote  sensor 

is powered up (for example after a change of batteries), a random 

security code is transmitted and this code must be synchronized with 
the  base  station  to  receive  weather  data.  Thus  if  battery  change 
happened on remote sensor side, then the base station must be 
power up again to re-learn the transmitter.

3)  Wait  3  minutes  or  until  the  outdoor  temperature  is  displayed  in  the 

weather  station.  Do  not  press  any  keys  before  outdoor  sensor 
data  received
.  The  wireless  weather  station  can  receive  up  to  3 
temperature  sensors.  If  you  have  purchased  additional  remote 

sensors, repeat step 1) for all extra sensors. However, ensure that 

you leave 10 seconds in between the reception of the last sensor and 
the  set-up  of  the  following  sensor. The  wireless  weather  station  will 

number the sensors in the order of set-up, i.e. the first temperature 

sensor  will  have  the  temperature  displayed  with  CH1.  If  only  have 
one sensor, CH1 won’t be display.

4) After the learning mode, the base station will start the radio controlled 

time reception. The receiver will start RCC time reception period for 

10 minutes maximum, and no weather data will be received during 

this  period  of  time.  If  RCC  signal  can’t  be  synchronized  with  the 
base station within 1 minute, the signal search will be cancelled and 
will  automatically  resume  every  hour  on  the  hour  until  the  signal  is 
successfully captured. Regular RF link will be established once RCC 

reception routine is finished.

5) Mount the units, ensuring that the receiver can still pick up the signal 

from  the  transmitter.  To  measure  outdoor  temperature,  place  the 
transmitter outdoors. It will transmit the temperature from its location.
