Thank you for purchasing this quality TIMEX® brand product. Please read these instructions COMPLETELY to fully understand
the features and functions of this clock, and to enjoy its benefits. Make sure to keep this guide handy for future reference.
This device complies with part 15 of the FCC rules and RSS-210 of IC rules subject
to the following two conditions:
1- This device may NOT cause harmful interference, and
2- This device must accept any interference received, including interference that may
cause undesired operation.
WARNING: Changes or modifications to this unit not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with limits for a Class B digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
To receive product information, register your product online. It's quick & easy!
However, There is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
WHAT IS AN ATOMIC CLOCK?
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
An Atomic clock is a timepiece that maintains accuracy up to one second per million years
using the most precise method of time synchronization, radio signals. In North America, the
National Institute of Standards and Technologies (NIST) operates an Atomic clock in Fort
Collins, Colorado, that transmits the time codes via the radio station WWVB.
• Consult the dealer or an experienced radio/TV technician for help.
This quality TIMEX® clock includes a built-in receiver that picks up the Atomic radio signal
from WWVB. To maintain the best possible reception, place the unit so that the backside
faces in the general direction of Colorado. What's more, the IntelliTime® technology built
into this clock makes for hassle-free automatic setting and resetting for daylight saving time.
NOTE: The manufacturer is not responsible for any radio or TV interference caused by unauthorized
modifications to this equipment. Such modifications could void the user authority to operate the
equipment.
Patent numbers: 5.978.738: 6.076.044: 6.597.990
PLEASE NOTE: Due to solar radiation in the atmosphere, the atomic clock signal is weaker
during the day. Most synchronization will happen at night when there is less interference.

Relocate or reposition the clock, making sure
the backside of the unit is facing in a direction
toward Colorado from your location.
Heavy stone or metal walls can obstruct the
signal and disrupt reception. Place the clock
at least 3 feet (0.91 m) from other electronic
devices (i.e. TV’s, microwaves, computers,
etc.) that can interfere with wireless signals.

Battery Choice & Temperature Range:
extended periods of extreme cold temperatures (below
-4°f/ -20°c) can cause alkaline batteries to function
improperly. this may cause the outdoor wireless
sensor to stop transmitting temperature readings. we
recommend using lithium batteries in extreme low
temperature conditions to ensure continued operation of
the outdoor sensor.
You may be experiencing interference from
other wireless devices using the same radio
frequency channel. Relocate the main unit
and/or the wireless sensor. Both units must
be within 100 feet (30m) of each other. Make
sure units are placed at least 3 feet from other
electronic devices or appliances that may
interfere with the wireless communication
(i.e. TV’s, microwaves, computers, etc.)
You may need to reset both units by
Poor Outdoor
Sensor Reception
(No bars)
For the digital atomic clock we recommend only alkaline batteries.
Placement of the Clock:
Place the clock in an area free of dirt and dust. To help ensure an accurate
indoor temperature measurement, be sure to place the main unit out of
direct sunlight, and away from any heat sources or vents in your home.

Relocate the main unit and/or the wireless
sensor. Both units must be within 100 feet
(30m) of each other. Make sure units are
placed at least 3 feet from other electronic
devices or appliances that may interfere
with the wireless communication (i.e. TV’s,
microwaves, computers, etc.)
This clock may be hung on a wall using the integrated wall-hanging hole,
or you may place the unit on a tabletop or other flat surface using the
swing-out stands.
You may need to reset both units by
removing and re-installing the batteries.
Placement of the Outdoor Sensor:
The wireless temperature sensor MUST BE PLACED OUTDOORS to capture and relay the
outdoor temperature to the clock display unit. You may place your wireless temperature
sensor outside up to 100 feet (30m) from the clock, as shown.
Display Not Working
Check to make sure the batteries are installed
correctly. Use only fresh STANDARD “AA”
batteries, not generic or extra strength. Make
certain that the batteries are FRESH. If the
expiration date on your batteries is less than 6
years away, they may not contain a full charge
and can be weak.
The sensor is water resistant and is designed
for outdoor use. However, to extend the life
of the product, place it in an area protected
from harsh weather elements. To ensure an
accurate temperature reading, be sure the
sensor is out of direct sunlight and away from
any heat sources.

Future Forecast Icon
SETTING THE CLOCK MANUALLY
The future forecast feature automatically gives you the predicted weather forecast icon
for the next 12 to 24 hours based on an advanced algorithm that analyzes barometric
pressure changes and temperature. This weather forecaster will provide the most
accurate forecast that a single stations instrument can provide.

NOTE: You do NOT need to turn off the atomic clock to set the time manually. Once the clock receives the signal, it will adjust the
clock accordingl. However, you may choose to deactivate the atomic clock feature completely if you prefer to manually control
the clock or if you live in a remote area that does not readily receive the atomic signal. As long as the atomic clock is ON, it will
automaticlly adjust itself to the correct time, overriding your manual setting.
Press the UP (s) ARROW to or DOWN (t) ARROW buttons to turn OFF
