RECEPTION OF SENSOR SIGNAL
OPERATING THE MAIN UNIT
1. Remove the battery door and insert 2 new AA
size batteries as per the polarity information
marked on the battery compartment.
2. Press “RESET” key to restart the clock.
3. Slide “°C/°F” switch to select between Celsius
and Fahrenheit.
4. Slide the battery door back on.
5. Press “+/CHANNEL” key to select the desired
channel.
Note When the sensor signal is received, the icon “ ”
will be displayed on the LCD.
RECEPTION OF RADIO CONTROLLED TIME SIGNAL
The time and calendar are radio-controlled. The current
time and calendar are automatically synchronized with
the atomic clock signal from Fort Collins, Colorado.
When used for the first time (after inserting batteries
or pressing “RESET” key), the clock will start to search
for the atomic clock signal and the signal reception
icon will flash for 5 minutes.
SIGNAL RECEPTION INDICATOR
The wave segment flashing means time signals are
being received. The signal quality could be classified
into 3 types:
Note
1. The unit will automatically search for the time
signal at 2:00am (3:00am or 4:00am is also
available if the signal is not received at 2:00am),
8:00am, 2:00pm, and 20:00 each day.
2. Always place the unit away from electrical
devices such as televisions, computers,
telephones, etc.
3. Avoid placing the unit on or next to metal plates.
4. If possible, place the unit next to a window.
Signal reception is greatly decreased when located
in closed areas like basements or metal buildings.
5. Do not start reception in moving vehicles or trains.
TIME AND CALENDAR MANUAL SETTING
If you are out of reach of the Radio Controlled
transmitter or if the reception is not reachable, the
time and calendar can be set manually. As soon as the
signal of transmitter is received again, the clock will
automatically synchronize with the exact time and
calendar.
1. In normal time mode, press “SET CLOCK” key
once to enter the time setting mode.
2. Press “+/CHANNEL” or “-/MIN.MAX.” key to
change the settings.
3. Press “SET CLOCK” to confirm. The setting order
is: 12/24-hr format, time, time zone offset, year,
day/month format, date.
4. Press “SET CLOCK” key to save and exit the
setting mode.

Projection Alarm Clock
with Indoor / Outdoor Thermometer and Ice Alert
Model: EW98
USER MANUAL
Thank you for your purchase of this Projection Alarm
Clock. Please read these instructions carefully and
keep the manual well for future reference.
The receiver unit has a clear and easy-to-read display
that shows the indoor temperature, time, calendar, the
maximum & minimum temperature records in the past 24
hours as well as the outdoor temperature measured and
transmitted from the remote sensors. It is able to receive
and display readings from up to 3 remote sensors.
The 433 MHz technology means no wire installation is
required and you can place the sensors within 30m
(100ft) from the main (indoor) unit.
This product is designed to synchronize its date and
time automatically once it is within range of the WWVB-60
signal from the atomic clock in Fort Collins, Colorado.
OPERATING THE SENSOR
1. Remove the battery door and slide “CHANNEL”
switch to CH 1. (When using additional sensors,
make sure each sensor is assigned a different
CHANNEL number.
2. Insert 2 new AAA batteries, matching polarities
(+/-).
3. Press the “RESET” key .
4. Slide the battery door back on.
Note
• Place the sensor in location away from direct
sunlight and rain.
• Do not place the sensor more than 30 m (100 ft)
from the main (indoor) unit.
• Position the sensor so that it faces the main
(indoor) unit, minimizing obstructions such as
doors, walls, and furniture.
• Place the sensor in a location with a clear view to
the sky, away from metallic or electronic objects.
• Position the sensor closer to the main unit during
cold winter months as below-freezing
temperatures may affect battery performance
and signal transmission.
The transmission range may vary depending on many
factors. You may need to experiment with various
locations to get the best results.
Standard Alkaline batteries contain significant amounts
of water. Because of this they will freeze in low
temperatures of approximately -12°C (10°F).
Disposable Lithium batteries have a much lower
threshold for temperature with an estimated freezing
range of below -30°C (-22°F).
Wireless ranges can be impacted by a variety of
factors such as extremely cold temperatures. Extreme
cold may temporarily reduce the effective range
between the sensor and the base station. If the unit’s
performance fails due to low temperature, the unit will
resume proper functioning as the temperature rises
to within the normal temperature range (i.e. no
permanent damage will occur to the unit due to low
temperatures).
