User manual LA CROSSE TECHNOLOGY WT535

[. . . ] If reception is not successful within approximately 10 minutes, either manually set the time or wait for the clock to receive DCF time. Usually, the Projection clock will attempt to receive the DCF signal in the next following hour. When this is successful, the received DCF time will override the manually set time. The date is also updated with the received DCF time (Please refer also to notes on "Radio Controlled Time" and "Manual Time Setting"). [. . . ] The projection image can also be adjusted to 4 upright positions, each with a rotation of 90º. 1. distance of the projection is 2 meters) Adjust the intensity of the projector light with the key Adjust the projection image in an upright position with the key The distance of the Projection clock should be at least 1. 5-2. 0 meters away from interfering sources such as computer monitors or TV sets. Avoid placing the alarm clock onto or in the immediate proximity of metal, doors, windows frames or structures. Within thick concrete rooms such as basements and tower blocks, the DCF-77 signal is naturally weaker. In extreme cases, place the alarm clock closer to a window and/or point its front or rear towards the general direction of the Frankfurt/Main transmitter (avoid positioning within close proximity of metal frames or structures). 3. Note: The projector will only project the current time. It will not project the seconds, date or temperature information. RADIO CONTROLLED TIME: 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 every 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 Projection clock receives this signal and converts it to show the precise time and so when within this range the received time is completely accurate. Note: Users may be located in areas where atmospheric disturbances are the direct cause for not receiving the DCF77 frequency signal. During nighttime, atmospheric disturbances are usually less severe and reception is possible in most cases. With a single daily reception, it is adequate for the alarm clock to keep time deviation to below 0. 5 seconds in a period of 24 hours. When the clock is trying to receive the DCF signal, the reception and the time icons will flash on the LCD. Once the signal is "locked", the DCF-77 tower icon will stay fixed on LCD and the received time will automatically correct the manually set time. As well as the time, the date will also be received by the Projection clock and will be displayed accordingly in the calendar section of the LCD. If the clock is not able to receive the DCF signal, the reception and the time icons will not be displayed. CHECKING FOR DCF-77 RECEPTION: The Projection clock will automatically start scanning for the DCF-77 frequency signal after the battery is inserted. In normal surroundings (for example away from interfering sources such as TV sets), it takes between 3-5 minutes to receive the signal. If after 10 minutes after having inserted the batteries into the alarm clock and the DCF-77 signal is not received, then check the following list before manually setting the time (see Manual time setting): ALARM SETTING: Alarm icon Alarm time To set alarm: 1. Press and hold the AL/HR key, the (((·))) icon will appears and the AL icon on the LCD starts flashing. Set the hours and minutes of the desired alarm time by use of the AL/HR (hours) or the MODE/MIN (minutes) keys respectively. Once the alarm time is set, press the SNOOZE key to confirm and exit or wait approximately 8 seconds for automatic timeout. Time DCF-77 Tower icon TO ACTIVATE / DEACTIVATE THE ALARM: Press the AL/HR key. The alarm icon (((·))) will appear/disappear indicating that it is ON or OFF. [. . . ] When it receives the signal, then the DCF tower icon will stay fixed on the LCD. If reception has been unsuccessful, then the DCF tower icon will disappear but reception will still be attempted the following hour. To change to a different time zone (±9 hours): 1. In normal mode display, press and hold down the MODE/MIN key to enter the time setting mode. When the desired time zone is selected, press the SNOOZE key to confirm and exit or wait for about 8 seconds for automatic return to the normal mode display. [. . . ]
