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).

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:

No signal

Weak signal Excellent signal

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.
