SETTING UP:
When one transmitter is to be used
1. First, insert the batteries to the transmitter (see “How to install and replace
batteries in the Thermo-hygro transmitter”below).
2. Within 2 minutes of powering up the transmitter, insert the batteries to the
Temperature Station (see “How to install and replace batteries in the
Temperature station”below). Once the batteries are in place, all segments of the
LCD will light up briefly. Following the indoor temperature and the time as 12:00 will
be displayed. If they are not shown in LCD after 60 seconds, remove the batteries
and wait for at least 60 seconds before reinserting them. Once the indoor data is
displayed user may proceed to the next step.
3. After the batteries are inserted, the Temperature Station will start receiving data
signal from the transmitter. The outdoor temperature and humidity should then be

7
displayed on the Temperature station. If this does not happen after 2 minutes, the
batteries will need to be removed from both units and reset from step 1.
4. In order to ensure sufficient 915 MHz transmission however, this should under good
conditions be a distance no more than 100 metres between the final position of the
Temperature Station and the transmitter (see notes on “Positioning” and “915 MHz
Reception”).
When more than one transmitter is to be used
1. User shall remove all the batteries from the temperature station and transmitters
and wait 60 seconds if setting has been done with one transmitter before.
2. Insert the batteries to the first transmitter.
3. Within 2 minutes of powering up the first transmitter, insert the batteries to the
Temperature Station. Once the batteries are in place, all segments of the LCD will

8
light up briefly. Following the indoor temperature and the time as 12:00 will be
displayed. If they are not displayed in the LCD after 60 seconds, remove the
batteries and wait for at least 60 seconds before reinserting them.
4. The outdoor temperature and humidity from the first transmitter (channel 1) should
then be displayed on the Temperature station. Also, the signal reception icon will be
displayed. If this does not happen after 2 minutes, the batteries will need to be
removed from both units and reset from step 1.
5. Insert the batteries to the second transmitter as soon as the outdoor temperature
and humidity readings from the first transmitter are displayed on the temperature
station.
Note: User shall insert the batteries into the second transmitter within 30 seconds of
reception of the first transmitter.

6. The outdoor temperature and humidity from the second transmitter and the
"channel 2" icon should then be displayed on the Temperature station. If this does
not happen after 2 minutes, the batteries will need to be removed from all the units
and reset from step 1.
7. Insert the batteries to the third transmitter as soon as the "channel 2" icon and
outdoor data are displayed on the temperature station. Then within 2 minutes, the
channel 3 outdoor data from the third transmitter will be displayed and the channel
icon will shift back to "1" once the third transmitter is successfully received. If this
does not happen, user shall restart the setting up from step 1.
Note: User shall insert the batteries into the third transmitter within 30 seconds of
reception of the second transmitter.
