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:

TEMPERATURE TRANSMITTER:

The outdoor temperature is measured and transmitted to the Temperature Station every 16 seconds approximately. The range of the Temperature Transmitter may be affected by the temperature. At cold temperatures, the transmitting distance may be decreased. Please bear this in mind when placing the transmitter.

915 MHz RECEPTION CHECK

The Temperature Station should receive the outdoor temperature data within a few minutes after setup. If the temperature data are not received about 2 minutes after setup (the signal reception icon does not appear), please check the following points:

1. The distance of the Temperature Station or transmitter should b e

at least 1.5 to 2 meters away from any interfering sources such as computer monitors or TV sets.

2. Avoid positioning the Temperature Station onto or in the immediate

proximity of metal window frames.

3. Using other electrical products such as headphones or speakers

operating on the same signal frequency (915MHz) may prevent correct signal transmission and reception.

4. Neighbors using electrical devices operating on the 915MHz signal

frequency can also cause interference.

Note:

When the 915MHz signal is received correctly, do not re-open the battery cover of either the transmitter or the Temperature Station, as the batteries may spring free from the contacts and force a false reset. If this happens accidentally, all units must be reset (see Setting up above) otherwise transmission problems may occur.

The transmission range is about 330 ft. (100 m) from the transmitter to the Temperature Station (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up above).

POSITIONING THE TEMPERATURE STATION:

The Temperature Station comes attached with foldout table stand, which provides the option of table standing the unit in addition

to wall mounting. Before wall mounting, please check that the outdoor temperature values can be received from the desired locations.

To wall mount:

1. Fix a screw (not supplied) into the desired wall, leaving the head extended out by about 5mm.

2. Hang the Temperature Station onto the screw. Remember to ensure that it locks into place before releasing.

POSITIONING THE REMOTE TEMPERATURE SENSOR

The remote temperature sensor can be placed onto any flat surface or wall mounted using the

bracket which doubles as a stand or wall mount base.

To wall mount:

1. Secure the bracket onto a desired wall using the screws and plastic anchors.

2. Clip the remote temperature sensor onto the bracket.

Note: The mounting surface can affect the transmission range. If, for instance, the unit is attached to a piece of metal, it may then either reduce or increase the transmitting range. For this reason, we recommend not to place the unit on any metal surfaces or in any position where a large

metal or highly polished surface is in the immediate vicinity (garage doors, double glazing, etc.). Before securing in place, please ensure that the Temperature Station can receive the 915MHz signal from the temperature transmitter at the positions that you wish to place them.

CARE AND MAINTENANCE

Extreme temperatures, vibrations and shocks should be avoided as these may cause damage to the unit and give inaccurate forecasts and readings.

When cleaning the display and casings, use a soft damp cloth only. Do not use solvents or scouring agents as they may mark the LCD and casings.

Do not submerge the units in water. Furthermore, fix all parts in place where the units are adequately protected against moisture and rain.

Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of the recommended type.

Do not make any repair attempts to the unit. Return them to their original point of purchase for repair by a qualified engineer.

Opening and tampering with the unit may invalidate their guarantee.

Do not expose the units to extreme and sudden temperature changes, this may lead to rapid changes in forecasts and readings and thereby reduce their accuracy.
