To turn on illumination manually
Press L in any mode to illuminate the display for about one second.
• The above operation turns on illumination regardless of the current auto
light switch setting.
• Illumination is disabled while the Barometer/Thermometer or Altimeter
Mode setting screen is on the display.
About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on, whenever you
position your wrist as described below in any mode.
Note that this watch features a “Full Auto EL Light”, so the auto light switch
operates only when available light is below a certain level. It does not
illuminate the display under bright light.
Moving the watch to a position that is parallel to the ground and then tilting
it towards you more than 40 degrees causes illumination to turn on.
• Wear the watch on the outside of your wrist.
Warning!
• Always make sure you are in a safe place whenever you are reading
the display of the watch using the auto light switch. Be especially
careful when running or engaged in any other activity that can result
in accident or injury. Also take care that sudden illumination by the
auto light switch does not startle or distract others around you.

Questions & Answers
Question: How does the barometer work?
Answer: Barometric pressure indicates changes in the atmosphere, and by
monitoring these changes you can predict the weather with
reasonable accuracy. Rising atmospheric pressure indicates good
weather, while falling pressure indicates deteriorating weather
conditions.
The barometric pressures that you see in the newspaper and on the
TV weather report are measurements corrected to values measured
at 0 m sea level.
