EMR898_GB(02/05) 12/1/03, 10:36 AMPage 12-13 Adobe PageMaker 6.5C/PPC
INDOOR TEMPERATURE READINGS
The main unit also reads the temperature of its own surroundings. It displays
this temperature on the second line of the LCD display (→ p.11,B.). This
second reading is updated approximately every 78 seconds.
LCD Display Description
Soon after the batteries have been installed, the main
unit immediately reads and displays the surrounding
temperature on the second line of the LCD screen.
GB
REMOTE TEMPERATURE READINGS
The remote temperature readings are displayed on the top line of the
LCD screen display (→ p.11,A.).
LCD Display Description
Soon after the batteries have been installed, the
main unit searches for signals from the remote unit.
This process takes about 4 minutes.
Upon successful reception, the remote unit
temperature is displayed on the top line of the
LCD (→ p.11.A.).
If no signals are received from the remote unit, the
top temperature remains blank and the unit stops
searching. To force the main unit to search once
again, use a blunt stylus to press the RESET Hole
located at the back (→ p.11,A.).
Kinetic Wave Display
The Kinetic Wave Display is only shown on the top line of the main
unit. It displays the current receiving signal status from the remote
unit to the main unit. The display is shown in three different forms:
LCD Display DescriptionSignal
Blinking signal
The main unit is searching for
signals from the remote unit.
Radiating signal
Temperature readings from
the remote unit are securely
registered.
No signal
No signals received from the
remote unit. Searching has
stopped.

TEMPERATURE RANGE
This product is designed to work under the widest temperature ranges
possible. However, if the temperature falls above or below the device s
operation range, the display will change to the following:
LCD Display Description
When the LCD screen displays HHH , the
temperature is above the measuring range of the
remote or main unit (see Specifications → p.24 ).
When the screen displays LLL , the temperature
is below the measuring range of the remote or
main unit (see Specifications → p.24 ).

CLOCK FUNCTIONS
Your product is designed to synchronize its calendar clock
automatically once it is brought within range of the radio signal from
the U.S. Atomic Clock. When the main unit is new and just out of the
box, synchronization with the U.S. Atomic Clock can take up to 72
hours. When the unit is receiving the signal, the Radio Reception
symbol with start to blink. Generally, complete reception takes around
2 to 10 minutes, depending on the strength of the radio signal. The
clock automatically searches for radio signal at 1AM, 2AM, 3AM,
9AM, 3PM and 7PM daily.

Radio Reception is disabled.
Reception can be affected by a number of factors. For best
reception, place the device away from metal objects and
electrical appliances. Other causes for signal interference
NOTE
include electrical transmission towers, steel reinforced
construction, and metal siding. Reception is ideal when placed
near a window.
Even though there are areas that may have more difficulty in
NOTE
receiving a signal, the Atomic Clock contains accurate quartz
movement and will retain precise timing even if the signal is
occasionally missed.
ENABLING / DISABLING RADIO RECEPTION
To manually disable the reception of the Radio Frequency (RF) signal,
press and hold
(→ p.4,C.) for 2 seconds until the Radio Reception
symbol completely disappears.
To enable the reception again, press and hold
(→ p.4,C.) for 2
seconds. The Radio Reception symbol will blink and the unit will search
for the RF signal automatically.
