La Crosse Technology WS-2510 manual Changing batteries Base station, Information on fault removal

4.Changing batteries

Base station

If the flat battery symbol appears in the display (see page 9) all batteries must be changed for ones of the same type as described in Section 2 (Battery operation, page 5).

Always change all the batteries and use only high-quality alkaline cells.

Please note!

After changing the batteries, the weather station will be re-initialized, all stored settings will be lost and will have to be re-entered.

Wireless sensors WS-2510-20, WS-2510-22, WS-2510-27

The batteries in these sensors have a life of up to three years (alkaline batteries).

They must be changed when the display of the appropriate sensor in the base device display does not appear for more than 24 hours and there is no general and longer lasting interference of the radio path, which can usually be recognized by the fact that data transmission from other, neighboring sensors has also broken down (see section 5,“Interference”). The battery is changed by opening the battery compartment on the rear of the sensor housing, removing the discharged battery and inserting two new AA alkaline batteries in the correct polarity according to the markings in the battery compartment. Replace the battery compartment cover and the sensor is ready for use. After a few seconds the data from this sensor will appear on the display.

Other components of the system do not require a battery change as they are powered by solar cells. Integrated batteries provide power during the hours of darkness and periods of bad weather.

5.Information on fault removal

Possible faults that could impair the correct display of the transmitted readings are:

No reception – The distance between sensor and receiver is too great.

Reduce the distance between the sensor and the receiver.

No reception – dense shielding materials are positioned between the sensor and the receiver (thick walls, reinforced concrete, ...)

Find another position for the sensor and receiver. See also section 6 (“Range”).

Sensor batteries are discharged.

Change batteries.

Sensor is blotted out by a source of interference (radio device, radio head set/loudspeaker) Remove source of interference or find alternative location for sensor and receiver.

A newly linked wireless sensor (e.g. after change of battery) is automatically accepted by the system and the associated data is displayed.

Often the interference is of a temporary nature (radio telephony) or can be removed very easily. If there are radio headsets, wireless baby phones or similar devices operating on 433MHz in your house or in the neighborhood their turn- on time is normally limited. Most of these devices permit change to a disturbance-free frequency.

A measure such as this effectively cuts out interference.

A wireless sensor interferes with other devices in the 433MHz range

The transmissions from a wireless sensor can interfere with other devices on the same channel for a short period (every 3 minutes for about 200 ms).

Further information on installation and removal of interference

The receiver device contains the receiver for the WWVB time signal and the data reception for the sensors. It should be set up or mounted so that the rod antenna is as vertical as possible and stable reception of the time signal as well as the wireless sensors is possible. For the best WWVB reception please orientate the receiver correspondingly.

Under critical reception conditions the sensor test mode makes it easier to choose the best possible location. For this purpose, the sensor concerned is put in test mode, so that every four seconds data is transmitted.

To activate the test mode remove the batteries from the indoor sensors and the magnets from the outdoor sensors and refit them after a delay of at least 60 seconds.
