Operation Guide 5098/5099/5101
When wearing the watch, make sure that its face is not
blocked from light by the sleeve of your clothing.
The watch may enter a sleep state (page E-15) if its face is
blocked by your sleeve even only partially.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become
particularly hot when exposed to the following conditions for long periods.
On the dashboard of a car parked in direct sunlight
Too close to an incandescent lamp
Under direct sunlight

Power Levels
You can get an idea of the watch's power level by
observing the movement of the x Second Hand in the
regular timekeeping.
If the x Second Hand is moving normally at one-second
intervals, power is at Level 1.
If the x Second Hand is moving at two-second intervals,
power is at Level 2, which is quite low. Expose the watch
to light as soon as possible so it can charge.
Moves at two-second
intervals.

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
However, when using the watch outside of areas covered by time calibration signals,
you will have to adjust the settings manually as required. See "Specifying Your
Current Location and Setting the Time" (page E-27) for more information.
This section explains how the watch updates its time settings when the city name
selected as the current location is in Japan or China, and is one that supports time
calibration signal reception.
If your location setting is this: The watch can receive the signal from the transmitter
located here:
HONG KONG (HKG)
Shangqiu City (China)
TOKYO (TYO)
Fukushima (Japan), Fukuoka/Saga (Japan)
E-16
Even when the watch is within range of a transmitter, signal reception may be
impossible due to the effects of geographic contours, structures, weather, the time
of year, the time of day, radio interference, etc. The signal becomes weaker at
distances of approximately 500 kilometers, which means that the infl uence of the
above conditions becomes even greater.
Signal reception may not be possible at the distances noted below during certain
times of the year or day. Radio interference may also cause problems with
reception.

−
As of January 2011, China does not use Daylight Saving Time (DST). If China does
go to the Daylight Saving Time system in the future, some functions of this watch
may no longer operate correctly.
Using this watch in a country covered by a time calibration that is different from the
countries it supports may result in incorrect time indication due to local application
of summer time, etc.

Approximate Reception Ranges
To get ready for a receive operation
1.
Keep the watch in an area normally exposed to bright light when storing it for long
periods. This helps to ensure that power does not run down.
Storing the watch for long periods in an area where there is no light or wearing it in
such a way that it is blocked from exposure to light can cause power to run down.
Make sure that the watch is exposed to bright light whenever possible.

c c Minute Hand stopped at 12 o'clock.
When power drops to Level 3, all functions will be disabled but the watch will
continue to keep time internally for about one week. If you recharge the battery
suffi ciently during this period, the analog hands will move automatically to the
correct setting and regular timekeeping will resume. After one week, all settings
(including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.
All regular timekeeping hands move to 12 o'clock and stop.
n Minute Hand (elapsed time) moves to 0 and stops.
Auto Receive becomes disabled.
Internal timekeeping functions continue to operate normally.
It can take up to 14 minutes for the watch to recover from the sleep state to normal
operation. Do not perform any button operations during that time.
