Daylight Saving Time
• The National Institute of Standards and

• Your La Crosse Technology® clock will read
this information (only if "DST" is set to "on" -)
and automatically advance the time one hour in
the spring and back an hour in the fall.
• Arizona: If you live in an area that does not
recognize DST you must de-activate Daylight
Saving Time by setting "DST" to "oF"

°F/°C Temperature Display:

Reception of the WWVB Radio signal:
• The clock must receive the WWVB Radio
Signal to automatically set the time, date and
weekday.
• The clock automatically starts the WWVB
signal search after 7 minutes of any restart or
changing of new fresh batteries. The radio
tower icon starts to flash.
• At 1:00 am, the clock automatically carries out
the synchronization procedure with the WWVB
signal to correct any deviations to the exact
time. If this synchronization attempt is
unsuccessful (the radio tower icon
disappears from the display), the system will
automatically attempt another synchronization
at the next full one hour. This procedure is
repeated automatically up to total 5 times.
• To start manual WWVB signal reception, press
the “WWVB SEARCH“ button. If no signals
received within 7 minutes, then the WWVB
signal search stops (the radio tower icon
disappears) and will start again at the next full
one-hour.
• To cancel RC reception and stop searching for
the WWVB radio signal, press the “WWVB
SEARCH“ button once. The radio tower icon
will disappear.
About WWVB Radio Signal Reception:
• A flashing radio tower icon indicates that the
WWVB signal reception has started.
• A continuously displayed radio tower icon
indicates that the WWVB signal was received
successfully during the last attempt. If the
clock attempts to receive the WWVB signal and

is unsuccessful, the tower icon will not be
continuously displayed on the LCD.
• We recommend a minimum distance of 2.5
meters (8 feet) to all sources of interference,
such as televisions or computer monitors
• Radio reception is weaker in rooms with
concrete walls (e.g.: in cellars) and in offices. In
such environments, place the system close to
the window.

Care and Maintenance
• Extreme temperatures, vibration and shock
should be avoided as these may cause
damage to the unit and give inaccurate
readings.
• Precautions shall be taken when handling the
batteries. Injuries, burns, or property damage
may be resulted if the batteries are in contact
with conducting materials, heat, corrosive
materials or explosives. The batteries shall be
taken out from the unit before the product is to
be stored for a long period of time.
• Immediately remove all low powered batteries
to avoid leakage and damage. Replace only
with new batteries of the recommended type.
• When cleaning the display and casings, use a
soft damp cloth only. Do not use solvents or
scouring agents as they may mark the LCD
and casings.
• Do not submerge the unit in water.
Furthermore, fix all parts in place where the
units are adequately protected against
moisture and rain.
• Special care shall be taken when handling a
damaged LCD display. The liquid crystals can
be harmful to user's health.

• Do not make any repair attempts to the unit.
Return them to their original point of purchase
for repair by a qualified engineer. Opening and
tampering with the unit may invalidate their
guarantee.
• Never touch the exposed electronic circuit of
the device as there is a danger of electric
shock should it become exposed.
• Do not expose the units to extreme and sudden
temperature changes, this may lead to reduce
their accuracy.
• Batteries are the single largest cause of
customer support cases. Please use plain
Alkaline batteries testing no less than 1.48 on
a voltmeter or with and expiration date 7 years
in the future.
Battery Replacement
• If you notice that the LCD appears faint or that
WWVB time reception is not working properly,
try a fresh set of batteries before contacting
customer support.
We recommend that you replace the
batteries in all units regularly to
ensure optimum accuracy of these
units. Please see the battery life in
the specifications below.
Help us to keep our environment clean. Return
used batteries to an authorized depot.
Troubleshooting
additional information on troubleshooting.
If the clock receives a clear signal it will set itself
perfectly.
If it does not receive a signal consider the
following:
• Battery - The La Crosse Technology® clock
must have a fresh battery to receive and
process the time signal.

• Location - Try a different location, ideally near
a window. It should be at least six feet from
computers, TVs, air conditioners, other Radio-
Controlled clocks and other electrical
appliances that cause interference.
• Weather - Electrical storms between you and
Colorado during the night will interfere with the
WWVB signal. Although we cannot control the
weather we can help you predict it (see
www.lacrossetechnology.com).
