18-HOUR BAROMETRIC PRESSURE HISTORY GRAPH:
The bar chart indicates the air pressure history trend over the last 18 hours in 5 steps, 0h, -3h, -
6h, -9h, & -18h. The columns represent the “hPa” at specific times. The “0” in the middle of this
scale is equal to the current pressure and each change (0, -3, -6, -9, -18) represents how high or
low in “hPa“ the past pressure was compared to the current pressure.
If the bars are rising, it means that the weather is getting better due to the increase of air pressure.
If the bars go down, it means the air pressure has dropped and the weather is expected to get
worse from the present time “0h“.
POSITIONING THE ATOMIC CLOCK:
There are two possible ways to mount the atomic clock:
Foldout leg stands or wall mount.
FOLDOUT LEG STAND
The two foldout leg stands are located on the back of the atomic clock. Pull
the leg stands out from the back of the atomic clock. Once the foldout leg
stands are extended, place the atomic clock in an appropriate location.
WALL MOUNT
Install one mounting screw (not included) into a wall within transmission
range of the transmitter, leaving approximately 3/16 of an inch (5mm)
extended from the wall.
Place the atomic atomic clock onto the screw, using the hanging hole on
the backside.
Gently pull the atomic clock down to lock the screw into place.
NOTE:
Always ensure that the atomic clock locks onto the screw before
releasing.

POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER
The remote temperature transmitter should be mounted vertically to avoid damage.
WALL MOUNT
Install one mounting screw (not included) into a wall within transmission
range of the atomic clock, leaving approximately 3/16 of an inch (5mm)
extended from the wall.
Place the transmitter onto the screw, using the hanging hole on the
backside.
Gently pull the transmitter down to lock the screw into place.
NOTE:
Always ensure that the transmitter locks onto the screw before
releasing.
TABLE STAND
Set the transmitter upright on a table or desk.
NOTE
: This is not recommended as the transmitter may blow over and be
damaged.
To achieve a true temperature reading, avoid mounting the outdoor transmitter where direct
sunlight can reach it. It is recommended to mount the outdoor temperature transmitter on a North-
facing wall or in any well shaded area. The maximum transmitting range in open air is 100-feet (30
meters) obstacles such as walls, concrete, and large metal objects can reduce the range.
Place both units in their desired location, and wait approximately 10 minutes before permanently
mounting to ensure that there is proper reception. The outdoor temperature transmitter is not
waterproof and should not be placed anywhere it will become submerged in water or subject to
standing water or snow.
