Power Requirements

This Projection Alarm Clock is powered by a 5 volt a/c power adapter

Alternatively, optional 2-AAA alkaline batteries may be used.

Half of all warranty issues can be resolved by ensuring a good power source.

A/C Power:

Insert the a/c cord into the Projection Alarm properly. Line it up and push it in.

Check that the outlet or power strip is working.

Note: Some outlets (living room, bedroom) turn off with the light switch.

Batteries:

We suggest name brand alkaline batteries. Overpowered or underpowered batteries may

cause loss of indoor readings, missing segments, dim display etc.

Use batteries dated at least six years in advance of the current year. Batteries dated earlier

than six years from now may still work, but may be unstable in performance.

Alkaline batteries manufactured this year will have an expiration date 10 years in the future.

Battery technology has improved and batteries will maintain voltage longer in storage.

However, the environment the batteries reside in for the 10 years can deplete the power.

Good name brand batteries make less noise, which reduces the chance of RF (radio

frequency) interference from the battery compartment. A minimum voltage of 1.48V for

each battery is necessary for proper performance.

Projection Alarm Clock Factory Restart

REMOVE POWER: Remove batteries and a/c cord from Projection Alarm Clock and

transmitter.

DISCHARGE ELECTRICITY: Press one of the buttons on the Projection Alarm Clock at

least 20 times to clear all memory. Verify that the Projection Alarm Clock is blank before

proceeding.

UNPOWERED 10 MINUTES: Let the Projection Alarm Clock sit with power removed for at

least 10 minutes.

POWER UP: Insert 5-volt A/C power cord or install fresh alkaline batteries in the Projection

Alarm Clock.

If the Projection Alarm does not display the indoor temperature after 30 seconds remove the

a/c power adapter and start the setup process again.

Accuracy

Indoor Temperature

Operating temperature range = 32 F to 122 F (0C to 50C)

Accuracy ± 2 degrees Fahrenheit 32 F to 122 F (0C to 50C)

Resolution = 0.1 degree F

Projection Alarm Clock

How tall are the Time Numbers?

The time numbers are 1.18 inches tall.

12-Hour or 24-Hour Time Format

Display the time in 12-hour or 24-hour format

La Crosse Technology, Ltd. Page 3

Default is 12-hour time.

Use the Program Menu to switch time formats.

Supported Time Zones

This Projection Alarm Clock offers seven time zones:

AST=Atlantic

EST= Eastern

CST= Central

MST= Mountain

PST= Pacific

AKT= Alaska

HAT=Hawaiian

The Projection Alarm Clock works in North America. Outside of North America, the projection

alarm clock will not receive a WWVB signal, but will keep time like a quartz clock.

Fahrenheit/Celsius

Projection Alarm Clock: Press and release the SET/°F/°C button on the back of the

Projection Alarm Clock to switch the temperature display from Fahrenheit to Celsius.

Inaccurate Indoor Temperature Reading

Side-by-side test: Place the Projection Alarm Clock next to your thermostat for 2 hours.

Compare temperatures. The temperature should be within 4 degrees to be within tolerance.

See the section on accuracy for details.

Look for heat sources such as sunlight, door or window frames, or reflected heat of cold.

Dashes, OFL or Stuck Indoor Temperature

This is generally a power related issue.

Batteries may be overpowered or underpowered. Remove batteries from Projection Alarm

Clock.

Press any button 20 times. Leave the Projection Alarm Clock unpowered for 1-2 hours.

Insert fresh alkaline batteries with correct polarity.

If the indoor Temperature is still dashes or OFL, the Projection Alarm Clock may need

replacement.

Does the clock have a backlight?

Yes, this projection alarm clock has a backlight.

A/C adapter:

The backlight can show continuously when operating the Projection Alarm Clock with the 5-volt

a/c adapter.

HIGH: The backlight is defaulted to HI (brightness) when the a/c adapter is in use.

LOW: Press and release the SNOOZE/LIGHT HI-LO-OFF button to dim the brightness of

the backlight.

OFF: Press and release the SNOOZE/LIGHT HI-LO-OFF button to turn the backlight off to

sleep.

Note: When the Adapter is NOT in use, the High-Low-OFF backlight feature is not available.

La Crosse Technology, Ltd. Page 4

Note: When the backlight is off, press any button to activate the backlight for 10 seconds, and

then it will turn off again.

Battery power:

Press and release the SNOOZE/LIGHT HI-LO-OFF button and the backlight will show for 10

seconds, when operating on batteries only.

IMPORTANT: When operating on a/c power, the backlight, projection and USB charging

port will turn off while the Projection Alarm Clock searches for the WWVB signal, to avoid

interference. The backlight and projection will return after the 2-10 minute search (which occurs

during the late night or early morning hours). Then the USB charging port will resume working.

Time is off by hours

Check to see if the WWVB Tower icon appears on the Projection Alarm Clock. If not, the

Projection Alarm Clock has not received a WWVB time signal in the past 24-hours.

Reposition the Projection Alarm Clock with the front or back facing Colorado.

Check that the Time Zone selected correctly reflects your location. Adjust the time zone in

the Program Menu.

Check that the DST indicator is correct for your location (most areas observe DST so this

should be ON). Adjust the DST indicator in the Program Menu.

Large buildings, metal roofed buildings and buildings or rooms full of electrical and/or radio

equipment make it difficult to receive the WWVB time signal.

Projection Adjustments

Battery Power: Press and release the SNOOZE/LIGHT button to show the projection for 10

seconds.

Note: Projection will not display constantly when operating on battery power.

A/C Power: Projection is displayed constantly unless turned off.

OFF: Hold the +/PROJ ON/OFF button to turn the projection OFF while operating on a/c

power.

ON: Hold the +/PROJ ON/OFF button to turn the projection ON while operating on a/c

power.

Rotate Projection: Press and release the PROJECTION button to rotate projection image

90 degrees. Press and release the PROJECTION button again to rotate another 90

degrees.

Change Projection Mode: Hold, then release the PROJECTION button to switch projection

modes. Watch the projection image to view the changes.

•Time and Indoor Temperature: alternate every 5 seconds (default)

•Time: Hold and release PROJECTION button

•Indoor Temperature: Hold and release PROJECTION button again

Projection not working

When operating on a/c power and no constant projection shows, yet it works when you press

the SNOOZE button please check:

La Crosse Technology, Ltd. Page 5

ON/OFF: Place your hand about 2'' from the projection lens. You should see a red dot. If

not, hold and release +/PROJ ON/OFF button once to check that projection was not

accidently turned off.

A/C CORD: The projection will continuously display if the a/c cord is attached correctly and

the projection is turned on.

Check that the a/c cord attached properly. Line up the cord and push it in the clock.

Once you are sure it is in correctly, remove the batteries. If the display goes blank, the

a/c cord needs adjustment.

Check that the outlet or power strip has power.

IMPORTANT: When operating on a/c power, the backlight, projection and USB charging

port will turn off while the Projection Alarm Clock searches for the WWVB signal, to avoid

interference. The backlight and projection will return after the 2-10 minute search (which occurs

during the late night or early morning hours). Then the USB charging port will resume working.

Daylight Saving Time

Dependent on your location, position of the clock in your home, and atmospheric

interference, it may take up to 5 nights for the change from Daylight Savings Time to

Standard Time and vice-versa to occur.

Check for a WWVB Tower Icon showing on your Clock. The tower icon indicates you have

received the WWVB signal from Ft Collins CO in the past 24-hours.

Check that the clock is in the correct Time Zone.

Check whether the DST indicator is ON or OFF. If the indicator is OFF the clock will not

change.

Check for fresh batteries. Without proper batteries, the antenna will have a harder time

picking up the signal.

Position the Projection Alarm Clock in a window (with the front or back) facing Ft. Collins,

Colorado and leave for up to five nights. If you do not have a window facing this direction,

locate the Clock near an outside wall and point the unit in this general direction.
