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
3. Adjust the projection image in an upright position with the
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.
