• Performing multiple sensor, illumination, or

beeper operations during a short period may
cause R (recover) to appear on the display.
Illumination, alarm, countdown timer alarm,
hourly time signal, and sensor operations will
be disabled until battery power recovers.
After some time, battery power will recover and
R (recover) will disappear, indicating that the
above functions are enabled again.

• Even if battery power is at Level 1 or Level 2, the Barometer/Thermometer

Mode or Altimeter Mode sensor may be disabled if there is not enough
voltage available to power it sufficiently. This is indicated by R (recover) on
the display.

• If R (recover) appears frequently, it probably means that remaining battery

power is low. Leave the watch in bright light to allow it to charge.

Certain charging conditions can cause the watch to become very hot. Avoid
leaving the watch in the areas described below whenever charging its
rechargeable battery. Also note that allowing the watch to become very hot
can cause its liquid crystal display to black out. The appearance of the LCD
should become normal again when the watch returns to a lower temperature.

• On the dashboard of a car parked in direct sunlight

• Too close to an incandescent lamp

• Under direct sunlight

After a full charge, timekeeping remains enabled for up to about five months.

• The following table shows the amount of time the watch needs to be

exposed to light each day in order to generate enough power for normal
daily operations.

• Since these are the specs, we can include all the technical details.

• Watch not exposed to light

• Internal timekeeping

• Display on 18 hours per day, sleep state 6 hours per day

• 1 illumination operation (1.5 seconds) per day

• 10 seconds of alarm operation per day

• 1 hour of altimeter measurement at 5-second interval, once per month

• 2 hours of barometric pressure measurement per day

• 6 minutes of signal reception per day

• Stable operation is promoted by frequent exposure to light.

This watch is preset with a number of city codes, each of which represents
the time zone where that city is located. When setting the time, it is important
that you first select the correct city code for your Home City (the city where
you normally use the watch). If your location is not included in the preset city
codes, select the preset city code that is in the same time zone as your
location.

• Note that all of the times for the World Time Mode city codes are displayed

in accordance with the time and date settings you configure in the
Timekeeping Mode.

1. In the Timekeeping Mode, hold down A until the city code starts to flash,

which indicates the setting screen.

2. Use D and B to select the city code you want.

• Make sure you select your Home City code before changing any other

setting.

• For full information on city codes, see the “City Code Table”.

• The following steps explain how to configure timekeeping settings only.

4. When the timekeeping setting you want to change is flashing, use D and/

or B to change it as described below.

3. Press C to move the flashing in the sequence shown below to select the

other settings.

Daylight Saving Time (summer time) advances the time setting by one hour
from Standard Time. Remember that not all countries or even local areas use
Daylight Saving Time.
The time calibration signals transmitted from Mainflingen (Germany), Anthorn
(England), or Fort Collins (the United States) include both Standard Time and
DST data. When the Auto DST setting is turned on, the watch switches
between Standard Time and DST (summer time) automatically in accordance
with the signals.

• Though the time calibration signal transmitted by the Fukushima and

Fukuoka/Saga, Japan transmitters include summer time data, summer time
currently is not implemented in Japan (as of 2007).
