La Crosse Technology WS-7091UD Resetting, Positioning the temperature transmitter, Battery Change

Note:

When the 433MHz signal is received correctly, do not re-open the battery cover of either the transmitter or Temperature station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Resetting below) otherwise transmission problems may occur.

The transmission range is around 25 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 Resetting below).

The transmitter’s transmitting range may be affected by exposure to extreme cold condition (-25°C) for long periods of time due to the nature of Alkaline batteries. Should this happen, the 433MHz signal may be weakenend and therefore result in a shorter transmitting distances caused by temperature level.

Resetting:

1.Remove batteries from both the outdoor transmitter and the Temperature station.

2.Wait at least 30 seconds and then repeat the procedures specified in Setting up (above).

Note:

Always wait at least 30 seconds after removing the batteries before reinserting, otherwise start up and transmission problems may occur. Also, remember when insertting, that both units have to reset and to always reinsert the batteries to the transmitter first.

Positioning the temperature transmitter:

TheTemperature Transmitter is supplied with a holder that may be attached to a wall with the three screws supplied. To attach to the wall, please follow the steps below:

1.Mark the wall using a pen through the holes in the holder to obtain the exact drilling position.

2.Drill holes in the wall at the points marked.

3.Screw holder onto wall.

There is also double sided tape included with the wall mount. This can be used instead of drilling. Please mount this on a smooth surface instead of a brick one. The surface can, however, affect the transmission range, for example: if 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 placing the unit on any metal surfaces or in any position where a

large metal surface is in the immediate proximity (garage doors, double glazing etc.). Before securing in place, please ensure that the Temperature Station can receive the signal from the Temperature Transmitter at the positions that you wish to situate them. The Temperature Transmitter clicks in or out of the holder easily. When inserting or removing the Temperature Transmitter from the wall holder please hold both units securely.

Positioning the Weather Station:

For wall mounting, please check that the outdoor temperature can be received outdoors 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.Using the Weather Station’s hanging hole, carefully hang it onto the screw. Remember to ensure that it locks into place before releasing.

Important notes:

•Avoid placing the units where they can be exposed to sudden changes in temperatures; i.e. direct sunlight, extreme cold and wet/moist conditions. This will help avoid any inaccurate readings and any possible damage to the unit.

•Should the unit be exposed to extreme and sudden temperature changes, it will lead to rapid changes in its forecast reading and thereby reduce its accuracy.

•Should the unit be moved to another location that is significantly higher or lower than its standing point (for example from the ground floor to the first floor of a house), then either reset the units or discard the readings weather forecasts for the next 12-24 hours. By doing so, this will allow allow sufficient time for the unit to operate at a constant altitude and thus enabling a more accurate forecest.

Care and Maintenance:

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

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

•Do not submerge the unit in water.

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

•Do make any repairs to the unit. Return it to its original point of purchase for repair by a qualified engineer. Opening and tampering with the unit may invalidate its guarantee.

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

Battery Change:

It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of these units.

Please participate in the preservation of the environment. Return used batteries to an authorised depot.
