SETTING UP:

1. First, insert the batteries into the temperature sensor. (see “Install and replace batteries in the temperature sensor“).

2. Immediately after and within 2 minutes, 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 12:00 and the "Oscar Outlook" 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.

3. After inserting the batteries into the sensor, the Weather Station will start receiving

data from the sensor. The outdoor temperature and the signal reception icon should then be displayed on the Weather Station. If this does not happen after 5 minutes, the batteries will need to be removed from both units and reset from step 1.

4. In order to ensure sufficient 915 MHz transmission there should be no more than 330

feet (100 meters) between the final position of the Weather Station and the sensor (see notes on “Mounting” and “915 MHz Reception”).

Note:

•

The Weather Station will receive one outdoor sensor only.

•

If the signal reception is not successful on the first frequency (915MHz) for 22 seconds, the frequency is changed to 920MHz and the learning is tried another 22 seconds. If still not successful the reception is tried for 22 seconds on 910MHz. This will also be done for re-synchronization.

•

If after 10 minutes, the Atomic time (WWVB time) signal has not been received, press the SET key to manually enter a time initially.

•

Daily WWVB reception is attempted at full hour between 12:00 am to 6:00 am. If the reception is successful, there will no reception attempt until the following day. When this is successful, the received time will override the manually set time. The date is also updated with the received time. (Please refer also to notes on “Atomic auto-set time -

WWVB Radio controlled Time” and “Manual Time Setting”).

BATTERY INSTALLATION INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION

The Weather Station uses 2 x AAA, IEC LR3, 1.5V Alkaline batteries. To install and replace the batteries, please follow the steps below:

1. Remove the cover at the back of the Weather Station.

2. Insert batteries observing the correct polarity (see marking).

3. Replace compartment cover.

INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE SENSOR

The temperature sensor uses 2 x AA, IEC LR6, 1.5V Alkaline battery. To install and replace the batteries, please follow the steps below:

1. Pull out the battery holder at the bottom of the sensor.

2. Insert the batteries, observing the correct polarity (see marking).

3. Replace the battery holder 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 random security code is assigned by the

sensor 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 authorized depot.
