Setup Information:
The Temperature Sensor
uses 2 x AAA, IEC LR3, 1.5V
battery. To install and replace
the batteries, please follow
the steps that follow:
Position the Atomic
Clock and the Outdoor
Sensor five to six feet
apart with nothing
between them.
Insert batteries into the Wireless Outdoor
Temperature Sensor first - it is important that
you do not insert the batteries into the Atomic
Clock yet.
You must insert the batteries into the Atomic
Clock within 3 minutes of inserting the
batteries into the Sensor.
Slide out the battery compartment lid at the
bottom of the Outdoor Sensor.
Insert the batteries into the Outdoor Sensor
first, observing the correct polarity (see
markings inside battery compartment).
Replace the battery holder on the unit.
Immediately after and within 3 minutes, insert
the batteries into the Atomic Clock, observing
the correct polarity (see markings inside
battery compartment). Replace the battery
cover. The Atomic Clock uses 2 x AA batteries
( IEC LR6, 1.5V ).
The outdoor temperature and the signal
reception icon
should be displ a yed on the
Atomic Clock. If this does not happen after 3
minutes, the batteries will need to be removed
from both units and re-inserted, following the
instructions above.
Note: In the event of changing batteries in any of
the units, all units need to be reset by following the
setting up proc e dures. 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
Atomic Clock in the first 3 minutes of power being
supplied to it
Note: 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
Page 4 of 12
the reception is tried for 22 seconds on 910MHz.
This will also be done for re-synchronization.
The Outdoor Temperature Sensor
Remote transmission of
outdoor temperature to
Temperature Station by
915 MHz
Shower proof casing
Wall mounting case
Mount in a sheltered
place. Avoid direct rain and sunshine.
Under the eaves of your home is an ideal
place.
Positioning the Temperature Sensor:
The Sensor is supplied with a holder that may be
attached to a wall with the two screws supplied.
The Sensor can also be positioned on a flat
surface by securing the stand to the bottom to the
Transmitter.
Note:
Before permanently fixing the Sensor wall base,
place all units in the desired locations to check that
the outdoor temperature reading is receivable. If
the signal is being received, the signal reception
icon
will be displayed on the Atomic Clock. In
event that the signal is not
received, relocate the Sensor or
move it slightly as this may help the
signal reception. To ensure a good
connection, there should be a
distance of no more than 200 feet
between the final position of the
Atomic Clock and the Sensor.
To wall mount the Temperature Sensor:
1. Secure the bracket onto a desired wall using the
screws and plastic anchors.
2. Clip the remote temperature sensor onto the
bracket.
WWVB (Atomic Time) Radio signal:
The clock must receive the WWVB Radio
Signal to automatically set the time, date and
weekday.
The clock automatically starts the WWVB on
the top of the hour between the hours of 12:00
AM and 6:00 AM.
If this synchronization attempt is successful
the radio tower icon
appears on the display.
