TO INSTALL AND REPLACE BATTERIES IN THE PROJECTION CLOCK
The Projection Clock uses 3 x AA, IEC LR6, 1.5V
batteries. To install and replace the batteries, please follow
the steps below (the battery cover is located at the back of the unit):
1.
Using a finger or other suitable object in the space at the
bottom center of the battery cover and pull to remove.
2.
Observing the correct polarity, insert the batteries (see
markings inside the battery compartment).
3.
After inserting the batteries, replace the battery cover by
clicking into place.
TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The transmitter uses 2 x AAA, IEC LR3, 1.5V batteries. To install and replace
the batteries, please follow the steps below:
1. Remove
the
cover.
2.
Insert batteries observing the correct polarity (see marking).
3.
Replace the battery cover on the unit.
SETTING UP
The Projection Clock can be either batteries-operated or powered by the provided AC-DC
adapter.
BATTERIES INSTALLATION
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, insert 3 x AA, IEC LR6, 1.5V batteries into the Projection Clock (See
“To install and
replace batteries in the Projection Clock”
above). All the segments of the LCD will light up briefly and a
“beep” will sound. Then the time as 0:00, the indoor temperature, and the outdoor temperature as “ - -.-
ºC” 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 batteries are used as the main power source:
1.
Projected image brightness, alarm volume and back-light strength would be weaker.
2.
Battery lifetime would be much less than 1 year.
