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.

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.

RESETTING

The Projection Clock and the transmitter need to be reset when one of the following conditions occur:

• Unsuccessful 433MHz signal reception.

• Malfunction on the units.

• Batteries replacement.

• Failure in detecting the air pressure during the setup operation (In this case, the weather icon,

“TENDENCY” icon, and both upward and downward arrows will be flashed.).

For resetting, remove all batteries from the units and unplug the AC-DC adapter from any power source. Wait at
least for 3 minutes before powering up the Projection Clock again. Proceed from step 1 in “Setting Up” above.

HOW TO USE THE PROJECTOR

(DIRECTION
key)

The projector projects the current time and the current outdoor temperature onto a wall or ceiling, preferable
within a darkened room. It can be adjusted forward and backward 180º for maximum projection range. Also,
the projection image can also be adjusted in 4 upright positions, each with a rotation of 90º.

To project the time or the outdoor temperature onto a flat surface:

1. Point the projection lens to the appropriate direction (maximum distance of the projection is 2 meters).

2. Press the DISPL key to select the desired mode for the projection. There are 3 display modes:

M 0 – projecting the current time only.
M 1 – projecting the current outdoor temperature only.
