La Crosse Technology WS-8157U-IT 915MHz Reception Check for Outdoor Temperature Transmitter

915MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER

The radio-controlled clock will receive the temperature data within 4 seconds. If the temperature data is not being received 2 minutes after setting up (or the display shows “- - -”), then please check the following points:

1.The distance of the radio-controlled clock or outdoor temperature transmitter should be at least 6 feet (2 meters) away from any interfering sources such as computer monitors or TV sets.

2.Avoid placing the receiver 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 915 MHz signal is received correctly, do not re-open the battery cover of either the outdoor temperature transmitter or radio-controlled clock, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting-upabove) otherwise transmission problems may occur.

The maximum transmission range is 330 feet (100 meters) from the outdoor temperature transmitter to the radio-controlled clock (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).

Note:

In case the radio-controlled clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc.), the time can be manually set (please refer to notes on Manual time setting).

POSITIONING

Before permanently mounting, ensure that the radio-controlled clock is able to receive WWVB signals from the desired location. Also, extreme and sudden changes in temperature will decrease the accuracy of the radio-controlled clock, and changes in elevation will result with inaccurate temperatures readings for the next 12 to 24 hours. These changes will require a 12 to 24 hour wait before obtaining reliable data.

To achieve a true temperature reading, avoid mounting where direct sunlight can reach the outdoor temperature transmitter. It is recommended to mount the outdoor temperature transmitter on a North-facing wall or in any well shaded area. The maximum transmitting range is 330 feet (100 meters) obstacles such as walls, concrete, and large metal objects can reduce the range.

Place both units in their desired location, and wait approximately 10 minutes before permanently mounting to ensure that there is proper reception. The outdoor temperature transmitter is not waterproof and should not be placed anywhere it will become submerged in water or be directly in the rain.

POSITIONING THE RADIO-CONTROLLED CLOCK:

There are two possible ways to mount the radio-controlled clock:

•use of the foldout table stand, or

•wall mounting

FOLDOUT TABLE STAND

The foldout table stand leg is located on the backside. Pull the stand out from the bottom center edge of the radio-controlled clock, below the battery compartment. Once the foldout table stand is extended, place the radio-controlled clock in an appropriate location.

WALL MOUNTING

1)Using a straightedge, horizontally space at 3.93“ (100 mm) three screw positions on a wall.

2)Install three mounting screws (not included) into a wall within transmission range—leaving approximately 3/16 of an inch (5mm)

extended from the wall.

3)Place the radio-controlled clock onto the screws, using the hanging holes on the backside. Gently pull the radio-controlled clock down to lock the screws into place.

Note: Always ensure that the radio-controlled clock locks onto the screws before releasing.

POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER

The outdoor temperature transmitter can be mounted with the use of screws:

MOUNTING WITH SCREWS

1)Remove the mounting bracket from the outdoor temperature transmitter.

2)Place the mounting bracket over the desired location. Through the two screw holes of the bracket, mark the mounting surface with a pencil.

3)Where marked, start the screw holes into mounting surface.

4)Screw mounting bracket onto the mounting surface. Ensure that the screws are flush with the bracket.

TROUBLESHOOTING:

Problem:	The LCD is faint.
Solution:	1)	Replace the batteries.
Problem:	No reception of WWVB signal
Solution:	1)	It may help reception to face the front of the radio-controlled clock in the
		general direction of Ft. Collins, Colorado.
	2)	Wait overnight for signal.
	3)	Be sure the radio-controlled clock is at least 6 feet (2 meters) from any
		electrical devices, i.e. TV sets, computers, or other radio controlled clocks.
