[. . . ] Use only the adapter provided with the projection clock and make sure that your household voltage is appropriate to the working voltage of the transformer. Otherwise your Projection clock may be damaged. POWER SUPPLIED BY BATTERIES AND AC/DC ADAPTER If the Projection clock is first powered by batteries and the power adapter is subsequently used for extended period of time, the main power source of the Projection clock will switch to AC/DC power. The batteries will then act as a backup power source in case of power failure. 44 TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER The Temperature Transmitter uses 2 x AA, IEC, LR6, 1. 5V batteries. To install and replace the batteries, please follow the steps below: 1. [. . . ] Preset alarm time 50 4. Day and Month DCF-77 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 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. Your radio-controlled Projection alarm clock receives this signal and converts it to show the precise time in summer or wintertime. 51 The quality of the reception depends greatly on the geographic location. In normal cases, there should be no reception problems within a 1500km radius of Frankfurt. Once the outdoor reception test period is completed, the DCF tower icon in the clock display will start flashing in the upper center. This indicates that the clock has detected that there is a radio signal present and is trying to receive it. When the time code is received, the DCF tower becomes permanently lit and the time will be displayed. If the reception is not successful at 02:00 am, then the next reception takes place the next hour and so on until 06:00am, or until the reception is successful. If the reception is not successful at 06:00 am, then the next attempt will take place the next day at 02:00 am. If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then please take note of the following: · Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 1. 5 - 2 meters. 52 Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window and/or point its front or back towards the Frankfurt transmitter. During nighttime, the atmospheric disturbances are usually less severe and reception is possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second. · FUNCTION KEYS There are 4 function keys located on the front of the projection alarm and one on the top. The function keys are: AL/HOUR, MODE/MIN, Projection Direction, Brightness, and SNOOZE. SNOOZE key 53 AL / HOUR key MODE/ MIN key Brightness key Projection Direction key SNOOZE key: · Activate snooze function · Activate the projection brightness at the highest level · Exit the setting modes · E. L. Back-light-On AL/HR key: · Enter alarm setting mode · Activate or deactivate alarm · Stop alarm and snooze function 54 · · Set the hours and day E. L. Back-light-On MODE/MIN key: · Enter time zone, manual time, year, day, month, 12/24 hour time display, ºC / ºF temperature format setting modes · Set the minutes, year, month, 12/24 hour time format, ºC / ºF temperature format · Toggle between temperatures, seconds, alarm time, and date display · Stop alarm and snooze function · E. L. Back-light-On · · Brightness key Set the brightness level of the projection (in A/C power mode):4 levels: High, Medium, Low, OFF E. L. Back-light On 55 · · Projection Direction key Press to rotate the time/ outdoor temperature projection image in 90° increments Press to activate the EL back-light MANUAL SETTINGS: The following manual settings can be changed when pressing the MODE/MIN key for: · Time zone setting · Manual time setting · Calendar setting · 12/24-Hour setting · °C/°F setting TIME ZONE SETTING The time zone default of the Projection clock is "0h". The current time zone value at the bottom of the LCD display starts flashing. The range runs from 0h to 12h, then ­12h to 0h, in consecutive 1-hour intervals. Confirm with the SNOOZE key and enter the Manual time setting. MANUAL TIME SETTING In case the Projection clock cannot detect the DCF-signal (for example due to disturbances, transmitting distance, etc. ), the time can be manually set. The clock will then work as a normal Quartz clock. Hour flashing Minutes flashing 1. The hour and the minute digits will start flashing. 57 2. 3. Use the AL/HOUR key to set the hour; MODE/MIN key to set the minute. Confirm with the SNOOZE key and enter the Calendar setting. Note: The unit will still try and receive the signal at 2:00 am despite it being manually set. When it does receive the signal, it will change the manually set time into the received time. CALENDAR SETTING The date default of the Projection clock is 1. [. . . ] Do not expose the units to extreme and sudden temperature changes, this may lead to rapid changes in forecasts and readings and thereby reduce their accuracy.
