LCD Features
The Weather Station with Atomic Clock can be set to
many different modes. The LCD shown is the normal
operating mode. The actual data shown will be
different, based on your local settings and conditions.
• The configuration of your clock may differ somewhat
from that shown in the illustration.
• AA or AAA size battery. This clock may use more
than one piece of battery. Please refer to the
engraved battery marks inside the battery
compartment for the correct battery type.
Quick Start
Battery Installation
Clock/Main Unit
1. Plug the main unit into the wall outlet using the
included 7.5V adaptor.
2. Insert 4 AAA batteries into the battery compartment
on the bottom of the main unit, ensuring proper
polarity as indicated. Batteries are for backup in
case AC power goes out.
Note: When a low battery icon appears in the indoor
temperature and humidity window on the LCD,
replace the batteries.
Wireless Temperature/Humidity Transmitter
1. Remove the battery door
2. Insert 2 AA batteries
Note: When a low battery icon appears in the outdoor
temperature and humidity window on the LCD,
replace the batteries.
Wireless Rain Gauge Transmitter
(2 AA batteries installed)
Battery Replacement:
1. Detach the outer case of the rain gauge unit by
rotating cover counter-clockwise ½”.
2. Unscrew the battery door.
3. Insert 2 AA batteries.
4. Screw the battery door.
Note: When a low battery icon appears in the outdoor
rain gauge window on the LCD, replace the batteries.
Battery Precautions
Do not mix old and new batteries.
Do not mix alkaline, standard (carbon-zinc) or
rechargeable (nickel-cadmium) batteries.
Warnings
• Do not expose the main unit to excessive force,
shock, dust, extreme temperature, direct sunlight or
humidity. Any of these conditions may shorten the
life of the unit.
• Avoid exposing the wireless transmitter to extreme
temperatures, water or severe shock.
• Avoid contact with any corrosive materials such as
perfume, alcohol or cleaning agents.
• Do not tamper with any of the internal components
of this clock. This will void the warranty and may
cause damage.
Operation
Clock/Main Unit
To ensure proper functioning of your clock with
indoor/outdoor temperature, humidity and rain gauge,
please follow the below procedure:
1. Insert new batteries in the main unit first (see
Battery Installation).
2. Insert batteries in the two remote units
(Temperature/Humidity Transmitter and Rain
Gauge Transmitter).
3. Do not touch any other buttons or settings on the
clock. It will automatically receive the remote
temperature/humidity, rain gauge data and indoor
temperature/humidity.
Remote Temperature/Humidity Transmitter
1. After installing the batteries (or pressing the
RESET button), the temperature/humidity RF
(radio frequency) signal is immediately sent to the
clock. The clock attempts to receive the RF
temperature/humidity signal for the first five
minutes and refreshes the RF temperature every
three minutes.
2. To select Fahrenheit or Celsius temperature units,
press °C/°F button on the remote unit.
3. Press SELECT button to select temperature or
humidity display. Press and hold SELECT button
for two seconds until LCD shows ( ),
temperature and humidity is displayed
alternatively. To stop scrolling temperature and
humidity display, press and hold SELECT button
again for two seconds until ( ) disappears.
4. If the RF temperature/humidity signal is not
received within five attempts, “
---
” appears in the
outdoor temperature window of the clock. In this
case, press the RE-SYNC button of the main unit,
then press RESET button on the back of the
transmitter. The clock then attempts outdoor/
humidity.
5. If the clock does not display the outdoor
temperature/humidity after six minutes, relocate
the clock or the transmitter until reception is
6

temperature/humidity are shown on the LCD.
Wireless Remote Temperature/Humidity and
Rainfall Transmission
The transmission frequency is 433MHz. The outdoor
transmission range is 100 feet from the main unit.
Obstacles, walls, etc. will reduce the transmission
range. Once the main unit is plugged in or the
batteries have been installed, it will start to receive
signals for ten minutes. Once batteries are placed in
the remote units, it will start to transmit
temperature/humidity/rainfall data to the main unit
every three minutes. Upon successful reception, the
remote/outdoor temperature/humidity and rainfall will
be shown in the remote temperature/humidity/rainfall
field on the LCD. The main unit automatically updates
the remote reading at three minute intervals.
Receiver Signal Indicator Icons
The following icons indicate the signal transmission
status on the LCD:
Transmission Troubleshooting
1. If the main unit does not receive signals within the
first ten minutes, a blank “-” appears in the OUT
TEMPERATURE/HUMIDITY or RAINFALL window
on the LCD. If at any time during operation a signal
is not received after five consecutive intervals, a
blank “-” appears. If this happens, press the
RE-SYNC button. The main unit will receive
signals for ten minutes.
2. If the remote unit’s batteries are running low, a low
battery icon appears in the OUT
TEMPERATURE/HUMIDITY or RAINFALL field.
Replace the batteries.
3. If the display unexpectedly goes blank, press the
RE-SYNC button on the main unit to force the
main unit to receive a signal. If this does not work,
check the following:
- The AC/DC adaptor is plugged in properly to the
wall and unit.
- The remote unit is still in place.
- The batteries in both the remote unit and the
main unit are still good. Replace if necessary.
- The remote transmitter is within range and the
path is clear of obstacles or other interference
(see “Interference” section). Shorten the distance
if necessary.
Interference
Signals from other household devices such as
garage-entry controls, doorbells and home security
systems may interfere with the temperature-data
transmission and may cause temporary reception
failure. This is normal and does not affect the general
performance of the unit. The transmission and
reception of the temperature/humidity/rainfall reading
will resume once the interference has stopped.
Manual Clock Setting
1. Press and hold SET button for two seconds until a
beep sounds to start clock setting. The year will
display in flashing characters on the clock time
portion of the LCD.
2. Press + / - buttons to adjust the year between
2004 and 2099.
3. Press SET button consecutively to proceed to
Month-Date setting; Hour-Minute setting;
12 Hour/24 Hour time; Display.
4. Press and hold / - for fast setting.
Setting the Alarm
Press + / - button once for a beep sound, press + / -
button again to set the alarm time.
Press and hold + / - for fast setting.
After setting, r / - button, the alarm is set.
