TO USE THE PROJECTOR POWER ADAPTER
The unit comes with an AC-DC adapter for using the projector for an extended period of time, such as
throughout the night.
To connect the AC-DC adapter:
Important!
Make sure that your household voltage is 230V! Otherwise it can result in damaging your
Projection Clock.
1.
Insert the 2 x AAA, IEC LR3, 1.5V batteries into the transmitter (See
“To install and replace batteries in
the Temperature Transmitter”
above).
2.
Within 3 minutes, connect the AC-DC adapter to a wall socket. Plug the adapter into the jack at the
bottom of the Projection Clock. All the segments of the LCD and the projection will light up briefly; and a
“beep” will sound. Then the time as 0:00, the indoor temperature, and the outdoor temperature as - -.-
°C
will be displayed.
3.
The Projection Clock will now start receiving outdoor temperature signal. Once the remote temperature
has been received and is displayed on the Projection Clock, the DCF-77 time code reception is
automatically started. This takes typically between 3 - 5 minutes in good conditions. This time
period is an
excellent opportunity to locate the transmitter in suitable location. In order to ensure sufficient 433 MHz
transmission however, this should, under good conditions be no more than 20 - 25 meters from where the
Projection Clock will be finally positioned (see notes on “
Positioning
” and “
Checking for
433 MHz
Reception
”).
4.
If after 10 minutes the DCF time has not been received, manually enter the time
.
The clock will
automatically attempt each hour to receive the DCF time. When this is successful, the received time will
override the manually set time. The date is also updated with the received time (Please refer also to notes
on “
DCF-77
Radio Controlled Time
” and “
Manual Time Setting
”).
Your Projection Clock is now operational!
Note:
If the Projection Clock is powered through the AC-DC adapter, the projection will be constantly ON at the
highest brightness level unless the brightness level is manually changed to a lower brightness level afterward.
The brightness of the projection can be changed accordingly to enhance the clarity of the projected time by
pressing the key.
If the Projection Clock is battery operated, only when the SNOOZE key is pressed, the projection will turn ON at
its highest brightness level. The intensity of the brightness level of the projection cannot be adjusted. Once the
SNOOZE key is released, there will be no projection.
Important!
If the DCF-77 signal is not being received, no key functions can be used. In that case, either wait
for the next reception of the DCF signal or proceed to manual time setting after reset of the clock
for activation of the key function.
BATTERIES POWERED WITH THE USE OF AC-DC ADAPTER
If the Projection Clock is first powered by batteries and the AC-DC adapter is subsequently used for extended
period of time, the main power source of the Projection Clock will switch to AC power. The batteries will then act
as a backup power source in the case of power failure.
