SETUP INSTRU CTIONS STEP BY S TE P

STEP 1:

• Insert the 5 volt A/C power adapter into the designated area (2) on the back
of the Projection Alarm.

• Insert the power adapter plug into a wall outlet for a continuous backlight.

• IMPORTANT: When operating on A/C power,

to avoid interference, the backlight, projection
and USB charge port, will turn off while the
Projection Alarm searches for the WWVB
signal. The backlight, projection and USB
charge port will function again after the 2-10
minute search.

STEP 2:

• Remove battery cover from Projection
Alarm, slide tab up and pull out to remove the cover (1).

• Insert 2 new AAA batteries (not included) into the back of the Projection
Alarm. Observe the correct polarity (see marking inside the battery
compartment).

• Do NOT mix old and new batteries.

• The Projection Alarm will light up and display indoor temperature and time

(12:00).

STEP 3:

• Ensure that the transmitter is within 10 feet of the projection
alarm.

• Remove battery cover from transmitter: Slide the battery cover
down and lift off the front.

• Insert 2 new AA batteries (not included) into the TX141
transmitter. Observe the correct polarity.

• Within 3 minutes, the projection alarm will show readings in
the Outdoor temperature area on the LCD.

Note: Use Alkaline batteries (or Lithium for temperatures below

-20°F /-28.8°C).

TROUBLESHOOTING

USB CHARGE PORT

The integrated USB charging port (on back) will charge your smart phone,
camera or other devices when the projection alarm is plugged into a power
outlet with the included 5V A/C adapter.
Note: This is a power-output charging port. The
charging port does not supply power to the
projection alarm.

Begin charging your external device by
connecting the device’s USB charging cable (not
included) to the USB charging port on the back of
the projection alarm. Charging times will vary.
Note: Some USB cables are for data transfer only
and cannot be used for charging. Make sure that the USB cable you use will
charge your device. Most USB cables included with mobile devices will work
for charging.

• USB Power Output: 0.5A maximum current

IMPORTANT: When operating on A/C power, the backlight, projection and

USB charging port will turn off while the Projection Alarm searches for the

SNOOZE/LIGHT/HI / LOW/ OF F (TOP)

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). The USB charging port will then resume working.

WWVB RADIO CONTROLLED TIME

The NIST radio station, WWVB, 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 Atomic Projection Alarm. However, due to the nature
of the Earth’s Ionosphere, reception is very limited during daylight hours. The
Atomic Projection Alarm will search for a signal every night when reception is
best.

WWVB RECEPTION ICON with full signal strength will appear on screen

if the reception of WWVB signal is successful.

• The tower icon is solid when the Projection Alarm has received the WWVB
signal.

• The tower icon will flash when searching for a signal.

• No tower icon displayed. The Projection Alarm was unable to receive a

signal at this time.

• Reposition the Projection Alarm for better signal reception or try again at
bedtime.

• Hold the -/TIME button to force a signal search at night when reception is
best.

• The Projection Alarm will start searching at UTC: 07:00 and if no reception
on the first attempt they will try again at 08:00, 09:00 and 10:00. Each
attempt will be at least 2 minutes and the most will be 10 minutes.

• If there is no signal or too much interference, the receiver will only be on for
2 minutes.

• If the signal is good, it may catch a signal in ABOUT 2-3 minutes. If the
signal is marginal it will try to catch a signal for up to 10 minutes.

• IMPORTANT: When operating on A/C power, to avoid interference, the
backlight, projection and USB charge port, will turn off while the Projection
Alarm searches for the WWVB signal. The backlight, projection and USB
charge port will function again after the 2-10 minute search which occurs
during the late night or early morning hours.

Note: In case the Atomic Projection Alarm is not able to detect the WWVB
signal (disturbances, transmitting distance, etc.), the time can be manually
set.

TEMPERATURE TRENDS

The indoor and outdoor temperature trend indicators are updated every 30
minutes. These trends represent temperature changes over the past three
hours.

Temperature rising more than 2°F /1°C in the past three hours
Temperature has not changed more than 2°F /1°C in the past
three hours
Temperature falling more than 2°F /1°C in the past three hours

The temperature trend indicators are shown next to the indoor temperature
and outdoor temperature readings.

LOW BATTERY

• When this icon

appears in the indoor (IN) reading section, replace the

batteries in the Projection Alarm.

• When this icon

appears in the outdoor (OUT) readings section, replace

the batteries in the outdoor transmitter.

CARE AND MAINTENANCE

• Do Not Mix Old and New Batteries

• Do Not Mix Alkaline, Standard, L it h i um or Rechargeable Batteries

• Do not expose the Project i on Alarm to extreme temperatures, vibrat i on or sh ock .

• Keep Projection Alarm dry.

• Clean the P rojection Alarm with a soft damp cloth. Do not use solv ents or scouring

agents.

• The Projection Alarm is not a toy. Keep it ou t of reach of ch il dren.

• The Projection Alarm is not to be used for m edi cal purpose or for public information. It is

for home use only.

• The specifications of th i s product may change without prior notice.

• Improper use or unau th ori z ed opening of housing will void the warranty.

• If the Projection Alarm does not work prop erly, change the batteri es and/or check the a/c

cord connection.

POS ITIONIN G OUTDOOR TRANSMITTER

Once the projection alarm shows th e outdoor temperature/humidity, place it and th e
transmitter in th e desired locations and wait approximately 1 hour before permanently
mounting the trans mitter to ensure that there is proper reception. The transmitter should be
mounted verticall y, in a shaded, protected area, at least 6 feet from the ground to avoid
damage and ensu re accu rat e readings. The transmitter is water resistant , not waterproof
and should not b e pl aced anywhere it will becom e submerged in water or subj ect to
standing water or snow.

Choose a location for the transmitter that i s with in range of the projection alarm and under
an overhang for accuracy . Wireless transmitting range in open air is over 200 feet (60
meters) from outd oor t ransmitter to projection alarm.

Opti on 1 :

• Install one moun ting screw (not included) in t o a wall l eaving approximat ely ½ of an inch
(12.7mm) extended.

• Place the tran smi tter onto the screw, using the hanging ho le on the
backside.

• Gently pull the transmitter down to lock th e screw i nto place.

Opti on 2 :

• Insert the mounti ng screw (not included) th rough the front of the transmitter
and into the wall.

• Tighten the screw to snu g (do not over tighten).

To achieve a true temperature/humidity reading, mount where direct sunlight cannot reach
the outdoor transmi tt er. M ount the outdoor tran smi tt er on a North-facing wall or in any well
shaded area. Und er an eave or deck rail work well. The m aximum transmitting range in
open air is over 200 feet (60 meters). Obstacl es su ch as walls, window s, stucco, concrete
and large metal obj ect s can reduce the range. Place the transmitter at least 6 feet in the air
to improve si gnal trans mission.
