SETTING UP: When one transmitter is used

1. First, insert the batteries to the transmitter (see “How to install and replace batteries in the Temperature 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 0:00 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 should then be 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, there should be a distance of no more than 330 feet between the final position of the Temperature Station and the transmitter (see notes on “Positioning” and “915 MHz Reception”).

Using Multiple Sensors with One Temperature Station

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 light up briefly. Following the indoor temperature and the time as 0:00 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.

4. The outdoor temperature 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 readings from the first transmitter are displayed on the temperature station.

Note: User shall insert the batteries into the second transmitter within 45 seconds of reception of the first transmitter.

6. The outdoor temperature from the second transmitter and the

"channel 2" icon should then be displayed on the Temperature station. If this does not happen after 2 minute, 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 is not happen, user shall restart the setting up from step 1.

Note: User shall insert the batteries into the third transmitter within 45 seconds of reception of the second transmitter.

8. In order to ensure sufficient 915 MHz transmission however, this

should under good conditions be a distance no more than 10 0

meters between the final position of the Temperature Station and the transmitter (see notes on “Positioning” and “915 MHz

Reception”).

IMPORTANT:

•

Transmission problems will arise if the setting for additional sensors is not followed as described above. Should transmission problems occur, it is necessary to remove the batteries from all units and start again the set-up from step 1.

•

If the signal reception is not successful on the first frequency (915MHz) for 14 seconds, the frequency is changed to 920MHz and the learning is tried another 14 seconds. If still not successful

the reception is tried for 14 seconds on 910MHz. This will also be done for re-synchronization.

HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE STATION

The Temperature Station uses 2 x AAA, Alkaline batteries. When batteries will need to be replaced, the low battery icon will appear on the LCD. To install and replace the batteries, please follow the steps belo w:

1. Lift up the battery compartment cover.

2. Insert batteries observing the correct polarity (see marking).

3. Replace compartment cover.

HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER

The Temperature transmitter uses 1 x IEC CR2032, 3.0V battery. When

battery needs to be replaced, the low battery icon will appear on the LCD of the Temperature Stationor replace battery every 12 months. To install and replace the batteries, please follow the steps below:

1. Remove the battery compartment cover at the back of the transmitter.

2. Insert the battery, observing the correct polarity (see marking).

3. Replace the battery cover on the unit.

Note:

In the event of changing batteries in any of the units, all reset by following the setup procedures. This is because a random security code is assigned by the transmitter at start-up and this code must be received and stored by the Temperature Station in the first few minutes of power supplying.

BATTERY CHANGE:

It is recommended to replace the batteries in all units every 12 months to ensure optimum accuracy of these units.
