Display Contents
Each press of (A) in the Timekeeping Mode toggles between the display information as shown below. Displaying the Current Home City
In the Timekeeping Mode, pressing (E) will display the name of the currently selected
Home City for a short while.
To return manually to what was shown before the Home City, press ( E ) . Shifting the Hands
Hand shift moves the hands out of the way for easy viewing of display information.

1. While holding down (B), press (D).
   This will shift the analog hands to allow easy viewing of display information.

Note
If you leave the watch with its hands shifted and do not perform any operation for about one hour, the hands will resume normal timekeeping automatically.
Solar Charging
This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.
Charging the Watch
When you are not wearing the watch, put it in a location where it is exposed to bright light. While you are wearing the watch, make sure that its face (solar panel) is not blocked from light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially. Important!
Depending on light intensity and local conditions, the watch may become hot to the touch when exposed to light for charging. Take care to avoid burn injury after charging. Also, avoid charging the watch under high- temperature conditions like the ones described below.
—On the dashboard of a vehicle parked in the sun
—Near an incandescent light bulb or other source of heat
— Under direct sunlight or in other hot areas for long periods
Checking the Charge Level
In the Timekeeping Mode, the current charge level is indicated by the mode hand.

1. Good ( high charge)
2. Good (medium charge)
3. Low Battery

Remaining Charge and Dead Battery
You can determine if the charge level is low by checking the hand movement. Functions become disabled as battery power goes low.
Important!
Should the battery go low or go dead, expose the face (solar panel) to lightas soon as possible.
Note
Exposing the watch face to light after the battery goes dead will cause the [CHARGE] indicator to appear and the second hand to rotate counterclockwise until it stops at
second 57. This indicates charging has started.
Low Battery Power
The second hand jumps at two-second intervals.
Dead Battery
All hands are stopped.
Charging Time Guidelines
The table below shows guidelines for approximate charging times.
Charging Times Required for 1 Day of Operation

Times Required to Achieve Next Charge Level
Sunny day, outdoors (50,000 lux)

Sunny day, near a window (10,000 Iux)

Overcast day, near a window (5,000 lux)

Indoor fluorescent lighting (500 lux)

Note
Actual charging time depends on the local charging environment.
Power Saving Function
Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 6 a.m. will cause the display to go blank, and the watch to enter Level 1 power saving. If the watch is left in this condition for six or seven days, the watch will enter Level 2 power saving.
Power Saving Level 1
The second hand stops at 12 o’clock and the digital display goes blank to save power. The watch can connect with a phone at this level.
Power Saving Level 2 :
All hands stop and the digital display goes blank t o save power. All functions are disabled.
Recovering from Power Saving Operation
Use one of the operations below to exit power saving.

• Press any button.
• Move the watch to a bright location.
• Trigger auto light by angling the watch towards your face.

Note
The watch will not enter power saving in the cases below.
— Alarm Mode
—While in the Stopwatch Mode
—While in the Timer Mode
You can enable or disable Power Saving.
Configuring Power Saving Function Settings
Note that the watch also may enter power saving if its face is blocked from light by your sleeve while you are wearing it.
