1Introduction
Thank you for your purchase of the Ambient Weather Radio Controlled Analog Wall Clock. The
following user guide provides step by step instructions for operation and troubleshooting.
2Quick Start Guide
1. Remove locking pin before use (Figure 1).
2. Set Time Zone and Daylight Savings Time switch (Section 7).
3. Insert the battery.
4. Hang the clock on the wall.
5. Wait 24-48 hours for the correct time to set.
3Overview
The radio controlled wall clock (RCC) updates time and date automatically using a radio receiver
from the atomic time transmitted from Fort Collins, CO, USA(WWVB).
This signal is shortwave, and travels thousands of miles by bouncing off of the ionosphere. The signal
is best received at night when there is no solar interference.
The radio controlled clock never requires setting, and automatically adjusts to daylight savings time
(DST). This feature can be overridden for locations that do not observe DST (examples, Arizona and
Hawaii).
Features include:
Hour, minute and second hands
Automatic daylight savings time update and leap year observation
Four time zone settings (Pacific, Mountain, Central, Eastern)
Long battery life
The radio controlled reception is attempted every two hours, and generally is successful at night. Just
one successful synchronization per day is sufficient to accurately set the clock to the second.
4Important Notes
Before using this product, please read the following :
1. Read these instructions –All operating instructions should be read before the unit is operated.
2. Operate and store in a dry location. Do not operate outside.
3. The product must be protected against electromagnetic fields, static electrical fields, extreme
temperatures, and moisture.
4. Clean only with soft damp cloth.
5. Do not use near any heat sources such as radiators, heat registers, stoves, or other device
(including amplifiers) that produce heat.
6. Refer all servicing to qualified service personnel. Servicing is required when the device has
been damaged in any way, such as liquid has been spilled or the device has been exposed to
rain or moisture, does not operate normally, or has been dropped.

7. This device shall not be exposed to dripping or splashing water and that no object filled with
liquids shall be placed on the device.
8. Do not attempt to dismantle, open or repair this product yourself. If a fault occurs, seek
advice from Ambient Weather support only.
9. The product must not be exposed to substantial mechanical strain or strong vibrations.
10. Do not leave packaging materials unattended. It may become a dangerous plaything for
children.
11. Handle the product with care. It can be damaged by dropping and vibration.
Battery Safety Instructions
1. If the battery electrolyte in the cells should get on your skin, thoroughly wash with soap and
water. If in the eyes, rinse thoroughly with cool water. Immediately seek medical attention.
2. Leaking or damaged batteries might cause acid burns when in contact with skin, therefore use
suitable protective gloves to handle corrupted batteries.
3. Correct polarity must be observed while inserting the batteries.
4. Batteries should be removed from the device if not used for a long period of time to avoid
damage through leaking.
5. Keep batteries out of reach of children. Batteries can be swallowed and represent a choking
hazard.
6. Batteries must not be dismantled, short-circuited or thrown into fire.
5Installation
1. The clock includes a suspension eye for hanging on a wall.
2. To ensure proper radio reception, the clock should not be placed near electronic devices or on
a metal wall (metal blocks radio signals).

2. On the back of the housing, insert one AA battery, observing the correct polarity. The
correct polarity is indicated in the battery compartment.
3. The second hand will run and stop at the 12:00 o’clock position, followed by the minute hand
and hour hand aligning to the 12:00 o’clock position. This confirms the clock hands are
operating properly.
4. The clock attempts to synchronize with the atomic clock for 10 minutes. If it synchronizes,
the clock sets properly. If it does not receive the signal from the atomic clock (very likely
during the daytime), the clock will begin running from the 12:00 position until the time
synchronization is successful.
The clock will attempt synchronization at the following times: 2:16:00, 4:16:00, 14:16:00,
and 16:16:00. During synchronization, the second hand may stop until the time is correct.
8Mechanical Deviation Adjustment
During normal operation, the second hand will resynchronize at 1:30, 9:30 and 17:30 for two minutes
to account for mechanical deviation. The resynchronization occurs for two minutes, and makes the
proper second hand adjustment.
During normal operation, the minute hand will resynchronize from 1:52 to 1:58. If the minute hand
deviates within two minutes, it will automatically adjust. If the minute deviates more than two minutes,
the clock hands will align to 12:00 and attempt resynchronization.
9Setting the Time Manually
If reception is not available, the clock date and time can be set manually.
To set manually, press and hold the M. SET button (Figure 1) for three seconds, and the clock second
hand will stop and enter the manual mode.
Next, press and hold the M. SET button again until the time is set to the current time.
The clock will begin updating again after the M. SET button has not been pressed for 6 seconds.
The clock will attempt synchronization at the following times: 2:16:00, 4:16:00, 14:16:00, and
16:16:00.
10Forced Radio Resynchronization
To force resynchronization from the atomic clock, press and hold the REC button for 3 seconds. The
hands will return to the 12:00 position.
The clock attempts to synchronize with the atomic clock for 12 minutes. If it synchronizes, the clock
sets properly. If it does not receive the signal from the atomic clock (very likely during the daytime),
the clock will begin running from the 12:00 position until the time synchronization is successful.
The clock will attempt synchronization every two hours (1:00, 3:00, 5:00, 7:00, 9:00, 11:00, 13:00,
15:00, 17:00, 19:00 and 21:00). During synchronization, the second hand will operate properly.

13Glossary of Terms
Term
Definition
DST
Daylight saving time (DST) or summer time is the
practice of advancing clocks during the lighter months so
that evenings have more daylight and mornings have
less. Typically clocks are adjusted forward one hour near
the start of spring and are adjusted backward in the
autumn.
RCC
A radio-controlled clock is a clock that is synchronized
by a time code bit stream transmitted by a radio
transmitter connected to a time standard such as an
atomic clock.
WWVB
WWVB is a NIST time signal radio station near Fort
Collins, Colorado. WWVB is the station that
radio-controlled clocks in most of NorthAmerica use to
synchronize themselves. The 70 kW ERP signal
transmitted from WWVB is a continuous 60 kHz carrier
wave, the frequency of which is derived from a set of
atomic clocks located at the transmitter site, yielding a
frequency uncertainty of less than 1 part in one trillion.

Problem
Solution
Radio controlled clock does not update or
time is wrong.
Hang the clock on a wall. Laying the clock flat
on a surface will result in poor reception.
Be patient. Wait at least one week before
contacting Ambient Weather. The RCC is a
shortwave signal originating near Fort Collins,
Colorado, and travels thousands of miles by
bouncing off the ionosphere. The signal is better
at night due to solar interference during the
daytime. The farther you are from Colorado, the
weaker the signal. Urban environments can also
affect the signal strength.
Locate the Clock at night near a window or
outer wall, and away from other radiating
sources, like wireless routers or TVs. This will
insure the best reception possible.
Replace the batteries in the clock if
required. Low batteries are often the cause for
weak reception.
Check your Time Zone Setting. Make sure
your time zone is set properly in the clock
settings.
Avoid closed in areas. Closed in areas such as
basements are not recommended.
The clock is off by increments of an hour.
Check your Time Zone and DST
Settings. Make sure your time zone and DST
switches are set properly.
The clock does not respond to commands.
Press the reset button on the back of the clock.
