TO INSTALL AND REPLACE BATTERIES INTO THE PROJECTION
CLOCK
The Projection clock uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the batteries, please follow the steps below:
1. Insert finger or other solid object in the space at the bottom center of the battery compartment and lift up to remove the cover.
2. Insert batteries observing the correct polarity (see marking).
3. Replace compartment cover.
In addition or instead of inserting batteries, the AC adapter can be used:
1. Connect the power adapter to a wall socket
2. Insert the adapter into the jack at the bottom of the clock
42
3. The Projection clock will now start receiving the DCF time signal. After approximately 3 to 5 minutes, the DCF time will be displayed (Also see "Setting up" below).
Important!
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
43
clock will switch to AC/DC power. The batteries will then act as a backup power source in case of power failure.
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. Remove the cover.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery cover on the unit.
Note:
In the event of changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is because a random security code is
44
assigned by the transmitter at start-up and this code must be received and stored by the Projection alarm clock in the first three minutes of power being supplied to it.
SETTING UP
The Projection clock can be batteries operated or powered by the provided 3.4V
AC/DC adapter.
1. First, insert 2 x AA, IEC LR6, 1.5V batteries into the projection clock (or use the
A/C adapter to power up). Once the batteries are in place, all segments of the
LCD will light up briefly. Then the indoor temperature, the time as 0:00, will be displayed. If the indoor temperature is not displayed after a few seconds, remove the batteries and wait for at least 1 minute before reinserting them. Once the indoor data is displayed proceed to step 2.
2. Within 1-1/2 minutes of activating the Projection clock, place 2 x AA, IEC LR6,
1.5V batteries into the transmitter.
3. After a few seconds of inserting the batteries into the transmitter, the projection clock will start receiving data from the transmitter. The remote temperature will
45
then be displayed on the clock. If this does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1.
4. When the transmitter is set up, there is a testing period. Then DCF-77 time code reception is automatically started just after the clock is activated. This takes typically between 3-5 minutes in good conditions. This time period is an excellent opportunity to locate the transmitter in suitable location outdoors. In order to ensure sufficient 868 MHz transmission however, the distance between the
Projection clock and the transmitter should not be more than 100 meters (see notes on “Positioning” and “868 MHz Reception”).
5. If after 10 minutes the DCF time has not been received, use the MODE/ MIN key to manually enter a time (and date) initially. The clock will automatically attempt to
Note: receive the DCF time each day at 2:00 am. When this is successful, the received time will override the manually set time.
Should the total time of inserting the batteries into the transmitter take longer than 1-1/2 minutes from the time of inserting the batteries into the projection clock then
46
temperature reception problems may occur. If the temperature is not being received, then see "868MHz reception", before resetting the units.
In the event of changing batteries to the transmitter, the projection clock needs to be reset. (See Resetting the projection clock)
RESETTING THE PROJECTION CLOCK
To reset the Projection clock to the factory default setting or in case of a malfunction or changing batteries to transmitter, please remove all batteries from the unit and unplug the AC/DC adapter from any power source. Wait at least for 3 minutes before powering up the Projection clock again.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of these units.
Please participate in the preservation of the environment. Return used batteries to an authorized depot.
47
PROJECTION OF TIME / OUTDOOR TEMPERATURE
Note:
The projection is a red light, not harmful under normal usage, yet care should be taken to avoid looking directly into the light.
1. When plugged into an AC outlet, the projection alarm can continuously project the time and the outdoor temperature
2. When operating on batteries alone, the projection alarm will only project when the
SNOOZE button is pressed or the alarm is sounding.
3. The projection will auto-focus for display from about 1.7 to 2.0 metres away. A dark surrounding will be necessary to clearly see the projection.
The direction of the display can also be rotated 360° in 90° increments by pressing the
Projection Direction button. The projector case can be rotated 180° to further help orient the projected display.
48
Note:
If the Projection clock is powered through the adapter, the projection will be constantly
ON at the highest brightness level unless the brightness level is manually changed to a lower brightness level afterwards. And the brightness of the projection can be change accordingly to enhance the clarity of the projected time by pressing the key.
If the Projection clock is battery operated, the projection will be ON at the highest brightness level only when the SNOOZE key is pressed. The intensity of the brightness level of the projection cannot be changed. If the SNOOZE is released, the projection will be turned OFF.
TOGGLE BETWEEN THE DISPLAY OF TEMPERATURES, SECONDS,
PRESET ALARM TIME AND CALENDAR
By pressing shortly the MODE/MIN key, you will toggle between the following displays:
1. Indoor and outdoor temperature

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.
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.
50
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.
DCF reception is done twice daily at 02:00 and 03:00 am. 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.
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.
51
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.

TEMPERATURE TRANSMITTER
The outdoor temperature is measured and transmitted every 4 seconds.
The range of the temperature transmitter may be affected by the temperature. At cold temperatures the transmitting distance may be decreased. Please bear this in mind when placing the transmitter.
868MHz RECEPTION
If the outdoor temperature data is not being received within three minutes after setting up (or outdoor display always show “- -. -” in the outdoor section of the
Projection clock during normal operation), please check the following points:
61
1.
2.
3.
The distance of the projection alarm clock or transmitter should be at least 2 metres away from any interfering sources such as computer monitors or TV sets.
Avoid placing the transmitter onto or in the immediate proximity of metal window frames.
Using other electrical products such as headphones or speakers operating on the
868MHz-signal frequency may prevent correct signal transmission or reception.
Neighbors using electrical devices operating on the 868MHz-signal frequency can also cause interferences.
Note:
When the 868MHz signal is received correctly, do not re-open the battery cover of either the transmitter or projection alarm clock, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units
(see “Setting up” above) otherwise transmission problems may occur.
The transmission range is around 100 metres from the temperature transmitter to the projection alarm clock (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see “Setting up” above).
62
POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER
The sensor is supplied with a holder that may be attached to a wall with the two screws supplied. The sensor can also be position on a flat surface by securing the stand to the bottom to the transmitter.
To wall mount:
1. Secure the bracket onto a desired wall using the screws and plastic anchors.
2. Clip the sensor onto the bracket.
63
Note:
Before permanently fixing the transmitter wall base, place all units in the desired locations to check that the outdoor temperature and humidity readings are receivable.
In event that the signal is not received, relocate the transmitter(s) or move them slightly as this may help the signal reception.
The mounting surface can, however, affect the transmission range. If for example the unit is attached to a piece of metal, it may then either reduce or increase the transmitting range. For this reason, we recommend not placing the unit on any metal surfaces or in any position where a large metal or highly polished surface is in the immediate proximity (garage doors, double-glazing, etc.). Before securing in place, please ensure that the Projection alarm clock can receive the 868 MHz signal from the
Outdoor Transmitter at the positions that you wish to situate them.
