    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.

  • Page 14: How To Install And Replace Batteries In The Temperature Transmitter

    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 Station- or replace battery every 12 months. To install and replace the batteries, please follow the steps below: Remove the battery compartment cover at...

  • Page 15: Battery Change

    Replace the battery cover on the unit. Note: In the event of changing batteries in any of the units, all units need to be reset by following the setup procedures. This is because a random security code is assigned by the transmitter at start-up and this code must be received and stored by the Temperature Station in the first few minutes of power supplying.

  • Page 28 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.
  • Page 29 915 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: The distance of the Temperature Station or transmitter should be at least 1.5 to 2 meters away from any interfering sources such as computer monitors or TV sets.
  • Page 30 Using other electrical products such as headphones or speakers operating on the same signal frequency (915MHz) may prevent correct signal transmission and reception. 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.
  • Page 31 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).

  • Page 35 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...
  • Page 37 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.

  • Page 38: Specifications

    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.
