FEATURES OF PROJECTION ALARM

Operation of these features is in section III

ABOUT WWVB (Radio Controlled Time)

The NIST (National Institute of Standards and Technology—Time and Frequency Division) WWVB
radio station is located in Ft. Collins, Colorado, and transmits the exact time signal continuously
throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through
the internal antenna in the projection alarm. However, due to the nature of the Earth’s Ionosphere,
reception is very limited during daylight hours. The projection alarm will search for a signal every
night when reception is best.

The WWVB radio station receives the time data from the NIST Atomic clock in Boulder, Colorado. A
team of atomic physicists is continually measuring every second, of every day, to an accuracy of ten
billionths of a second per day. These physicists have created an international standard, measuring a
second as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum. For more detail, visit
http://www.boulder.nist.gov/timefreq.htm. To listen to the NIST time, call [phone]. This number
will connect you to an automated time, announced at the top of the minute in “Coordinated Universal
Time”, which is also known as Greenwich Mean Time (GMT). This time does not follow Daylight
Saving Time changes. After the top of the minute, a tone will sound for every second. It is possible
that your projection alarm may not be exactly on the second due to the variance in the quartz.
However, the clock will adjust the quartz timing over the course of several days to be very accurate;
under 0.10 seconds per day.

QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.

1. We recommend beginning the set-up procedure at night when the
WWVB signal is easiest to receive.

2. It is also highly recommended to set the projection alarm in a window
or other area free of interference in the area of your home that is
closest to Colorado (the source of the WWVB signal).

NOTE: The above steps are not required but can help the projection
alarm receive the signal faster.

3. Place the batteries into the projection alarm clock.

4. DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.

NOTE: It is important to not press any buttons after inserting batteries as
this will interrupt the WWVB search sequence.

In this time the display will show both the indoor temperature and humidity. If the
station does not display both indoor temperature and indoor humidity after the 15
minutes please retry the set up as stated above. After both indoor temperature
and indoor humidity are displayed for 15 minutes you can place your projection
alarm in your desired location.

To complete the set up of your temperature station after the 15 minutes have
passed please follow the steps beginning on page 6.

DETAILED SET-UP GUIDE

I.

BATTERY INSTALLATION

A. PROJECTION ALARM

1. Remove the battery cover.

2. Observe the correct polarity, and install 2 AA batteries.

3. In addition or instead of inserting batteries, the AC adapter can be used. Simply plug
the adapter into the receptacle on the
underneath of the alarm clock and then plug
in adapter.

4. Replace the battery cover.

5. The projector will activate and remain on if
the alarm clock is plugged in. If only batteries
are used, the projector will only be activated
when a button is pressed. The projection is a
red light, not harmful under normal usage,
although care should be taken to not look
directly into the light.

Notes:

• After the batteries have been installed a tone will sound, and the LCD (Liquid

Crystal Display) will activate.

• The indoor temperature/humidity will be displayed. Also, the time will appear as

“-:--”.

• The WWVB search is automatically initiated, and a tower icon appears and

flashes with the time colon (no tower icon will appear if the WWVB is too weak to
be detected, and the time display will remain on “-:--”).

• While the WWVB search is being conducted various numbers will appear in the

time display.

• After 15 minutes, the projection alarm will either display the WWVB time, or

discontinue the search if the time is not found. If the search is cancelled “-:--” will
remain in the time LCD.

• The projection alarm will conduct a WWVB search every hour until the first signal

is found.

• Once the WWVB time is found, a search is automatically conducted nightly at

midnight.

• If the signal is found at midnight, the tower icon will remain, if not, another search

will take place every hour (until 6:00 am) until the signal is found successfully.

• If no signal is found during this period, the tower icon will not appear and the

clock will search again at 12:00 am the next night.

• The radio-controlled time receiver is located on the bottom side of the projection

alarm. When using the AC adaptor be sure to keep the adapter cord away from
the bottom side of the unit as if the wire is too close it can cause weakened
reception sensitivity.

VIEWING AND OPERATING
WITH MULTIPLE REMOTE
TEMPERATURE SENSOR UNITS

1.

To view the temperature of a different
remote temperature sensor unit, press
and release the “SET/CH” button. A
shift from one “boxed” number to the
next should be observed in the
OUTDOOR LCD.

2.

To view the Minimum/Maximum
temperature: first select from which
remote temperature sensor to read data
(indicated by the “boxed” number).
Pressing and releasing the
“MIN/MAX” button will toggle
through the minimum and maximum
indoor temperature, and the minimum
and maximum outdoor temperature.

3.

To reset the Minimum/Maximum
readings, press and hold the
“MIN/MAX” button for four seconds.

MOUNTING

Note: To achieve a true temperature

reading, avoid mounting in direct sunlight.
We recommend that you mount the remote
temperature sensor on an outside North­facing wall. The sending range is 80ft;
obstacles such as walls, concrete, and large
metal objects will reduce the range. Place
both units in their desired location before
permanently mounting.

A.

REMOTE TEMPERATURE

SENSOR

1.

Remove the mounting bracket from
the remote temperature sensor

2.

Mount using either screws or
adhesive tape.

3.

Reattach the remote temperature
sensor to the mounting bracket.

B.

THE TEMPERATURE STATION

1.

The indoor temperature station comes
with the table stand already mounted.
If you wish to use the table-stand, all

17

that is required is to place the indoor
temperature station in an appropriate
location.

2.

To wall mount, remove the table
stand. To do this, pull down on the
stand from the rear and rotate forward.

a)

Fix a screw (not included) into the
desired wall, and place the indoor
temperature station onto the screw
using the hanging hole on the
backside. Gently pull the indoor
temperature station down to lock the
screw into place.

TROUBLESHOOTING

NOTE: For problems not solved, please
contact La Crosse Technology via e-mail or
phone, or visit our website,
www.lacrossetechnology.com

Problem: The LCD is faint
Solution: Replace batteries

Problem: No outdoor temperature is

displayed.

Solution:

1) Remove all batteries, reinsert into remote
temperature sensor first, and then into the
indoor temperature station.

2) Place remote temperature sensor closer to
the indoor temperature station.

3) Be sure all batteries are fresh.

4) Place remote temperature sensor and
indoor temperature station in position so
the straight-line signal is not passing
through more than two or three walls.

19

Problem: Temperatures do not match if
units are placed next to each other.
Solution: Each temperature sensor is
manufactured to be accurate to within 1
degree plus or minus and under normal
conditions; so two temperature sensors could
be as much as 2 degrees different. However,
the difference can be exaggerated further
because the temperature sensors are
designed for different working
environments. The indoor sensor is less
responsive to ambient air currents because of
the shielding effect of the display's case. In
addition, the case can act as a heat sink to
absorb and store heat from external sources
(i.e. handling of the case or radiant heat). In
addition, the much greater range of the
outdoor temperature sensor requires a
different calibration curve than the indoor
range. Error is usually greater at the extreme
ends of a range, making it harder to compare
different ranges with different curves. Under
non-laboratory conditions, it is difficult to
compensate for the above factors and obtain
an accurate comparison.

MAINTENANCE AND CARE
INSTRUCTIONS

• Extreme temperatures, vibration, and

shock should be avoided to prevent
damage to the units.

• Clean displays and units with a soft,

damp cloth. Do not use solvents or
scouring agents; they may mark the
displays and casings.

• Do not submerge in water.

• Do not subject the units to unnecessary

heat or cold by placing them in the
oven or freezer.

• Opening the casings invalidates the

warranty. Do not try to repair the unit.
Contact La Crosse Technology for
repairs.
