HOW TO USE THE PROJECTOR
The projector projects the current time onto a wall or ceiling, preferably within a darkened room. It can be
adjusted forwards and backwards 180º for maximum projection range. The projection image can also be
adjusted to 4 upright positions, each with a rotation of 90º.
To project the time onto a flat surface
1.
Point the projection lens in the appropriate direction (max. distance of the projection is 2 meters)
2.
Adjust the intensity of the projector light with the key
3.
Adjust the projection image in an upright position with the
key
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.
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):
1.
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.
2.
Avoid placing the alarm clock onto or in the immediate proximity of metal, doors, windows frames or
structures.
3.
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).
Note:
Users may be located in areas where atmospheric disturbances are the direct cause for not receiving the DCF-
77 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.
