INSTALLING THE BATTERIES
Main unit
Clock back up
The clock and alarm time can be saved by using two AAA/LR03 (1.5V) batteries (not supplied). The
time may go forward or back slightly over time and may require resetting.
Battery insertion
1. Remove the battery compartment cover at the bottom of the unit.
2. Install two AAA/LR03 (1.5V) batteries matching the polarities shown in the battery
compartment.
3. Replace the battery compartment cover.
Note: For optimum performance, the battery should be replaced every 6 months.
Inserting batteries in the wireless sensor
1. Remove the screw from the battery compartment with a screwdriver.
2. Follow the steps in the previous section “Battery insertion”.
3. Tighten the screw.
Note: For optimum performance, the battery should be replaced every 10 months or when the outdoor
readings cannot be displayed properly.
Precautions when using batteries
1. Replace only with the same or equivalent type of battery.
2. Ensure you follow the correct polarities when installing the batteries (see marks in the battery
compartment). Reversing polarity may damage the unit.
3. Remove exhausted batteries as they may leak.
4. Dispose of batteries properly according to environmental regulations.
OPERATING INSTRUCTIONS

USING THE WEATHER STATION
Wireless temperature/humidity sensor
After installing the batteries, position the remote sensor outdoors no more than 15 metres from the
main unit. It can be mounted in two different ways:
• Using the hanger slot at the back, hang the remote sensor on the wall with a screw.
• You can also insert the suction cup in the hanger slot and press the suction cup rmly against a
window or other smooth surface.
Note:
• The building’s construction materials and how the main unit and remote sensor are positioned
can inuence the transmission range.
• Extend and position the remote sensor RF transmission antenna wire so that it points to the
main unit and minimize obstructions such as doors, walls, and furniture.
• It should not be exposed to direct sunlight, rain or snow, and should not be placed near high
power electrical appliances or inside strong magnetic elds.
Indoor/ Outdoor temperature/humidity indication
Press the button to display indoor ( ) or outdoor ( ) readings.
Hold down the M button to display temperature in Celsius (°C) or Fahrenheit (°F).
Outdoor
When batteries are installed, the remote sensor will transmit the outdoor temperature and humidity
readings at two-minutes interval. The main unit may take up to two minutes to receive the readings if
the signal is good. The main unit will then automatically update readings every two minutes.
If no signal is received from the remote sensor after ve minutes, the outdoor readings will not be displayed properly. You should place the remote sensor closer to the main unit or replace the batteries.
Weather station
The remote sensor detects humidity. An icon is displayed depending on the level of humidity (see
table below) .
GB 5
Icons displayed Humidity range Weather
19% - 40% RH Very dry
41% - 65% RH Dry
66% - 75% RH Mild
76% - 91% RH Humid
USING THE RADIO
Listening to the FM radio
1. Press the RADIO ON/OFF button to turn on the radio.
2. Turn the TUNING dial to search for an FM station. The TUNING dial indicator points to the
selected frequency.
3. Adjust the volume by turning the VOLUME dial.
4. To turn off the radio, press the RADIO ON/OFF button.
Note: Extend and position the FM antenna wire to achieve optimum reception.
