• Gibbous describes a moon phase when more than half is illuminated. Gibbous can be waxing or waning.
• New Moon occurs when the moon is between the earth and sun, so the illuminated portion of the moon is on the back
side facing the sun and we cannot see it. After a new moon, the illuminated (visible) portion will increase or wax until
the full moon occurs.
• Full Moon occurs when the earth, moon and sun are in approximate alignment with the moon and the sun on
opposite sides of the earth. The illuminated portion of the moon faces the earth, giving us complete visibility of one
side of the entire moon. After a full moon, the illuminated portion will decrease or wane until the new moon occurs.
• First Quarter and Last Quarter moons occur when the moon is at a 90 degree angle to the earth and sun. We see
half of the moon illuminated and half is in shadow.

When the symbol appears behind the time, replace the batteries in the atomic wall clock.
When the symbol appears near the outdoor temperature, replace batteries in the outdoor transmitter.
Please help in the preservation of the environment and return used batteries to an authorized depot.
Install Batteries in the Outdoor Transmitter
The Outdoor Transmitter uses 2 x AAA, IEC, LR3, 1.5V batteries. To install and replace the batteries, please follow the
steps below:
1. Slide the battery cover down and lift off the back of the transmitter.
2. Insert 2 NEW AAA batteries (not included) into the TX40U-IT transmitter. Observe the correct polarity.
Note: When changing batteries in any unit, all units need to be reset by following the setup procedures.
This is due to a random security code assigned by the transmitter at start-up. This code must be received
and stored by the atomic wall clock in the first 3 minutes of power being supplied to the transmitter. If the
atomic wall clock has been operating for more than 5 hours, remove batteries from the outdoor transmitter and the atomic
wall clock for at least 15 minutes before completing a restart.
Install Batteries in the Atomic wall clock
The atomic wall clock uses 2 x AA, IEC LR6 1.5V batteries. To install and replace the batteries, please follow the steps
below:
1. Remove battery cover from atomic wall clock: insert a solid object in the space
provided at the lower-central position of the battery cover, then push up and pull out
on the battery cover.
2. Insert 2 NEW AA batteries (not included) into the back of the atomic wall clock.
Observe the correct polarity (see marking inside the battery compartment). The
atomic wall clock will display time and indoor temperature.
3. Within 3 minutes the outdoor temperature should be displayed.
4. Keep the atomic wall clock and transmitter within 10 feet of each other during setup
(15 minutes).
• Do Not Mix Old and New Batteries
• Do Not Mix Alkaline, Standard, Lithium or Rechargeable Batteries
Note: If the atomic wall clock does not display indoor temperature after 60 seconds, remove batteries and
wait for at least 60 seconds before repeating the setup process.
Position the Atomic wall clock
The atomic wall clock provides the option of table standing or wall mounting. Before mounting, please check that
the outdoor data can be received from the desired locations.
Foldout stands: Simply unfold the legs on the back and place the atomic wall clock on a desk or table.
Wall mounted:
1. Fix a screw (not supplied) into the desired wall, leaving the head extended out by about 0.2” (5mm).
