First, insert the batteries into the Temperature transmitter. (see "Install and replace batteries in the Temperature transmitter"). Immediately after and within 30 seconds, insert the batteries into Weather station (see "Install and replace batteries in the Weather station"). Once the batteries are in place, all segments of the LCD will light up briefly. Following the time as 0:00 and the weather icon will be displayed. If these are not displayed after 60 seconds, remove the batteries and wait for at least 10 seconds before reinserting them. After inserting the batteries, the Weather station will start receiving data from the transmitter. The outdoor temperature and the signal reception icon should then be displayed on the Weather station. If this does not happen after 3 minutes, the batteries will need to be removed from both units and reset from step 1. In order to ensure sufficient 868 MHz transmission however, this should under good conditions be a distance no more than 100 meters between the final position of the Weather Station and the transmitter (see notes on "Mounting" and "868 MHz Reception"). Once the remote temperature has been received and displayed on the Weather station, the DCF time (radio controlled time) code reception is automatically started. This takes typically between 3-5 minutes in good conditions. 3. 4. 5. 34 Note: Daily DCF reception is done at 02:00 and 03:00 every day. If the reception at 03:00 is not successful, then at 04:00 and 05:00 and 06:00 there are other tries, until one is successful. If the reception at 06:00 is still not successful, then the next try takes place at 02:00 next day. If reception is successful, the received time will override the manually set time. (Please refer also to notes on "DCF-77 Radio Controlled Time" and "Manual Time Setting") HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE STATION The Weather Station uses 2 x AAA, IEC LR3, 1.5V batteries. When batteries will need to be replaced, the low battery icon will appear on the LCD. To install and replace the batteries, please follow the steps below: 1. 2. 3. Lift up the battery compartment cover. Insert batteries observing the correct polarity (see marking). Replace compartment cover. 35 HOW TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER The Temperature Transmitter uses 2 x AA, IEC LR6, 1.5V battery. To install and replace the batteries, please follow the steps below: 1. 2. 3. Remove the battery compartment cover at the back of the transmitter. Insert the batteries, observing the correct polarity (see marking). Replace the battery compartment 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 setting up procedures. This is because a security code is assigned by the transmitter at start-up and this code must be received and stored by the Weather station in the first 3 minutes of power being supplied to it. BATTERY CHANGE: It is recommended to replace the batteries in all units regularly to ensure optimum accuracy of these units (Battery life See Specifications below). Please participate in the preservation of the environment. Return used batteries to an authorised depot. 36 FUNCTION KEYS: Weather station: The weather station has four easy to use function keys.

(If not successful, the icon will not be shown in LCD) So user can easily see whether the last reception was successful (icon on) or not (icon off). For a better display clarity, the LCD screen is split into 4 sections. Section 1 - TIME AND ALARM · In normal mode display of radio controlled time · A reception tower symbol will be shown indicating that the DCF-77 time signal is scanned for (flashing) or received (steady). Note: The symbol will not be shown when radio time reception is not successful or when time reception function is turned off. · In normal display, the alarm icon will be shown when the alarm is turned on. Or when the snooze function is activated, the alarm icon will be flashing. Section 2 - INDOOR TEMPERATURE · Display the current indoor temperature and indoor MIN/MAX records · Display of low battery indicator (weather station) 40 Section 3 - WEATHER FORECAST AND WEATHER TENDENCY ICONS · Display of the weather to be expected in form of three weather symbols and two weather tendency indicators in form of an arrow, which change their appearance depending on the air pressure development Section 4 - OUTDOOR TEMPERATURE · Display the current outdoor temperature and outdoor MIN/MAX records · A signal reception symbol will be shown indicating that receiver is receiving outdoor temperature · Display of low battery indicator (transmitter) MANUAL SETTINGS: The following manual settings can be done in the setting mode: · Time zone · Time reception DCF ON/OFF · Manual time Press and hold the SET key for about 3 seconds to advance to the setting mode: 41 TIME ZONE SETTING: Time zone (flashing) The time zone default is "0" hour.

WEATHER FORECAST AND TENDENCY THE WEATHER FORECASTING ICONS : There are 3 weather icons in the third section of LCD which can be displayed in any of the following combinations : 45 Sunny Cloudy with sunny intervals Rainy For every sudden or significant change in the air pressure, the weather icons will update accordingly to represent the change in weather. If the icons do not change, then it means either the air pressure has not changed or the change has been too slow for the Weather station to register. However, if the icon displayed is a sun or raining cloud, there will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already at their extremes. The icons display weather forecasts in terms of getting better or worse, and not necessarily sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does not mean that the product is faulty because it is not raining. It simply means that the air pressure has dropped and the weather is expected to get worse but not necessarily rainy. 46 Note : After setting up, readings for weather forecasts should be disregarded for the next 12-24 hours. This will allow sufficient time for the Weather Station to collect air pressure data at a constant altitude and therefore result in a more accurate forecast. Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting feature is estimated to have an accuracy level of about 75% due to the varying areas the Weather Station has been designed for use in. In areas that experience sudden changes in weather (for example from sunny to rain), the Weather Station will be more accurate compared to use in areas where the weather is stagnant most of the time (for example mostly sunny). If the Weather Station is moved to another location significantly higher or lower than its initial standing point (for example from the ground floor to the upper floors of a house), remove the batteries and re-insert them after about 30 seconds. By doing this, the Weather Station will not mistake the new location as being a possible change in air-pressure when really it is due to the slight change of altitude. Again, disregard weather forecasts for the next 12 to 24 hours as this will allow time for operation at a constant altitude. THE WEATHER TENDENCY INDICATOR Working together with the weather icons are the weather tendency indicators (located on the left and right hand side of the weather icons). When the indicator points upwards, it m ...
