Oregon Scientific EW93 - Weather Station with RC Alarm Clock Manual

INTRODUCTION

The receiver unit has a clear and easy-to-read display that shows the indoor temperature, time, the maximum & minimum temperature records in the past 24 hours, the weather forecast icon 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.

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.

	Main unit is searching for the sensor(s) (the icon will be flashing)
	The sensor(s) cannot be found
	Sensor 1 has been found (the icon will be displayed, but won't flash)
and "--.-" (Outdoor temperature Area)	The sensor(s) cannot be found after operating the main unit for 15 minutes

Note
When the sensor signal is received, the icon " " will be displayed on the LCD.

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).

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 sensor or if the reception is not reachable, the time and calendar can be set manually. As soon as the signal of sensor 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.

Note

1. During the setting period, press and hold "+/ CHANNEL" or "-/MIN.MAX." key to speed up the change of settings.
2. The time zone indicators are abbreviated as below: P=Pacific, M=Mountain, C=Central, E=Eastern.

ALARM TIME SETTING

1. In normal time mode, press "SET ALARM" key once to enter the alarm time setting mode.
2. Press "+/CHANNEL" or "-/MIN.MAX." key to set hour/minute.
3. Press "SET ALARM" key to save and exit the setting mode. " " indicates alarm is ON.

Note

1. The alarm will be automatically turned on when you set the alarm time.
2. During the alarm time setting period, press and hold "+/CHANNEL" or "-/MIN.MAX." key to speed up the change of settings.

WEATHER FORECAST INDICATOR

This product forecasts the next 12 to 24 hours of weather within a 30-50 km (19-31 mile) radius with a 75% accuracy.

USING ICE ALERT FUNCTION

If the outdoor temperature range is -2.0ºC ~ 3.0ºC (28.4ºF ~ 37.4ºF), the ice alert indicator light will be turned on and flash.

BATTERY REPLACEMENT

If the low battery icon turns on next to the outdoor temperature reading, replace the sensor's battery with 2 AAA batteries.
If the low battery icon turns on next to the indoor temperature reading, replace the sensor's battery with 2 AA batteries.
