WT 775 - Radio controlled alarm clock instruction manual

Start the clock

Insert 1 x Mignon AA LR06 battery into the battery compartment and make sure the battery polarity (+/-) is as indicated. The hands (second, minute, hour) are adjusting to 12 o'clock position and the alarm clock enters into signal reception mode.

Signal reception mode

The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of less than one second in one million years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. The radio controlled alarm clock receives this signal and converts it to show the precise time in summer or wintertime.

Environmental reception effects

The clock obtains the accurate time with wireless technology. Same as all wireless devices, the reception is maybe affected by the following circumstances:

• long transmitting distance
  • nearby mountains and valleys
  • near freeway, railway, airports, high voltage cable etc.
• near construction site
• among tall buildings
  • inside concrete buildings
  • inside moving vehicles

- near electrical appliances (computers, TV's, etc) and metallic structures

Place the clock at a location with optimal signal, i.e. close to a window and away from metal surfaces or electrical appliances.

a. Automatic signal reception: The automatic signal reception starts by inserting the battery. After 2 to 5 minutes the hands will be adjusted to the correct radio controlled time according to the DCF-77 reception signal. Then, the time will calibrate several times a day with the DCF-77 signal reception signal (also independent setting of summer- and winter time).

b. Manual signal reception: Press and hold the WAVE button longer than 3 seconds to start the manual signal reception. The hands (second, minute, hour) are adjusting to 12 o'clock position and the clock enters into signal reception mode. If the signal is successfully received, the hands adjust automatically to the correct radio controlled time. This procedure takes approximately 2 to 5 minutes. If the signal reception is failed, the alarm clock takes the previously set time again. After the next successful signal

reception the time will be adjusted to the correct radio controlled time according to the DCF-77 reception signal.

Note: The DCF-77 reception is only available in Europe.

Manual time setting

Press and hold the SET button until the desired time is set.

Alarm time setting

Turn the alarm set knob in indicated direction until the desired alarm time is set.

Turn on/ off the alarm

Turn the ON/OFF switch to the ON position, the alarm will ring with a beep alarm when the set alarm time is reached. Turn it to the OFF position, the alarm will not ring.

EN4

Note: If the alarm is not interrupted or turned off, it stops automatically after 2 minutes and rings again after 12 hours.

Snooze alarm & light

Press the SNOOZE/LIGHT button (at the top of the case) to activate the snooze alarm after 5 minutes and turn on the light.

Reset

If the clock shows an incorrect time or after changing the battery, press the RESET button on the case back panel to re-start the alarm clock. The hands (second, minute, hour) are adjusting again to 12 o'clock position and the clock enters into signal reception mode. In successful signal reception the time will be adjusted to the correct radio controlled time according to the DCF-77 reception signal.

Precautions

• This main unit is intended to be used only indoors.
• Do not subject the unit to excessive force or shock.
• Do not expose the unit to extreme temperatures, direct sunlight, dust or humidity.
• Do not immerse in water.

Batteries safety warnings

• Use only alkaline batteries, not rechargeable batteries.
  • Install batteries correctly by matching the polarities (+/-).
• Always replace a complete set of batteries.
• Never mix used and new batteries.
• Remove exhausted batteries immediately.
• Remove batteries when not in use.
• Do not recharge and do not dispose of batteries in fire as the batteries may explode.
• Ensure batteries are stored away from metal objects as contact may cause a short circuit.
• Avoid exposing batteries to extreme temperature or humidity or direct sunlight.
• Keep all batteries out of reach from children. They are a choking hazard.

Use the product only for its intended purpose!

Consideration of duty according to the battery law

Old batteries do not belong to domestic waste because they could cause damages of health and environment. You can return used batteries free of charge to your dealer and collection points. As end-user you are committed

by law to bring back needed batteries to distributors and other collecting points!

Consideration of duty according to the law of electrical devices

This symbol means that you must dispose of electrical devices separated from the General household waste when it reaches the end of its useful life. Take your unit to your local waste collection point or recycling centre. This applies to all countries of the European Union, and to other European

countries with a separate waste collection system.
