Oscar Outlook Forecaster
• Temperature display in Fahrenheit (°F) or Celsius (°C) selectable
• Indoor and Outdoor temperature display with MIN/MAX recording
• All MIN/MAX recordings can be reset
• Low battery indicator
• Wall hanging or free standing
The Outdoor Temperature Sensor
• Remote transmission of outdoor temperature to Weather
Station by 915 MHz
• Weather-resistant casing
• Wall mounting case
• Mount in a sheltered place. Avoid direct rain and sunshine
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

6
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:

7
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

8
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.

LCD SCREEN AND SETTINGS:
*When the outdoor signal is successfully received by the Weather Station, this icon will be
switched on. (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). On the other hand, the
short blinking of the icon shows that a reception is currently taking place.
For easy viewing, the LCD screen is divided into 3 sections displaying the information for
time and indoor data, weather forecast, and outdoor data.
