OUTDOOR TRANSMITTER 915 MHz RECEPTION CHECK

The outdoor temperature, humidity, wind data are transmitted from thermo-hygro transmitter every 4.5 seconds; the rainfall data are transmitted from the rain sensor (optional) every 6.25 seconds. The receiver will be synchronized to the thermo-hygro transmitter and rain sensor (optional) then. The transmission range (up to about 330 feet /100 meters in open air) of the thermo-hygro transmitter/ rain sensor may be affected by the ambient temperature. At cold temperatures, the transmitting distance may be decreased. Please keep this in mind when placing the transmitter and the rain sensor.

If (1) the outdoor data is not being received within first several minutes after setting up; (2) the outdoor display always shows “- - -“ on the outdoor display; or (3) the reception icon of thermo-hygro transmitter (Mode 1) and rain sensor (optional) (Mode 2) is not displayed on the display, check the following things:

1.The distance of the Weather Station or transmitter/ rain sensor should be at least 5 to 6.5 feet (1.5 to 2 meters) away from any interfering sources such as computer monitors or TV sets.

2.Avoid positioning the Weather Center onto or in the immediate proximity of metal doors or window frames.

3.Using other electrical products such as headphones or speakers operating on the same signal frequency (915 MHz) may prevent correct signal transmission and reception.

4.Neighbors using electrical devices operating on the 915 MHz signal frequency can also cause interference.

Note:

When the 915 MHz signal is received, do not re-open the battery compartment cover of either the transmitter/ rain sensor or Weather station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur.

During normal operation, after the outdoor display shows "- - -", the weather station will change to receive the outdoor data every 15 minutes, until the data is read. Then the reception period for thermo-hygro transmitter will return to 4.5 seconds (6.25 seconds for rain sensor - optional).

If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up).

POSITIONING:

Prior to permanently mounting any of the units, please ensure the following points are considered:

Cable lengths of the units meet with your distance requirements at the point of fixing

Signals from the sensors can be received by the base station at points of mounting

La Crosse Technology Sensor Extension Cable

You can purchase a La Crosse Technology Extension Cable if you require additional length to properly mount your sensor. The extension cable is 32 feet in length and comes with the appropriate connecter attached. Please visit your local retailer or www.lacrossetechnology.com and click on the Buy button to locate an online dealer or other retailers.

Using phone cables or connections may damage your sensors because phone cables and connections have more resistance than the La Crosse Technology extension cable. Phone cables or connections are not recommended for use.

Note: Using extension cables will shorten battery life.

Warning: Never cut, splice, shorten or modify your sensor cables or extension cables. Doing so may damage your sensors and will void your warranty.

The Weather Station

The Weather Station has been designed to be hung onto wall or free standing with the two kinds of foldout stand.

To wall mount

Choose a sheltered place. Avoid direct rain and sunshine.

Before wall mounting, please check that the outdoor temperature and humidity 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 the by about 5mm.

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