Thermometer Precautions

•Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

Reversing the Displayed Moon Phase

The left-right (east-west) appearance of the Moon depends on whether the Moon is north of you (northerly view) or south of you (southerly view) as you view it.

You can use the procedure below to reverse the displayed Moon phase so it matches the actual appearance of the Moon where you are located.

•To determine the viewing direction of the Moon, use a compass to take a direction reading of the Moon at its meridian passage.

•For information about the Moon phase indicator, see “Moon Phase Indicator” (page E-68).

Moon Phase Indicator

Module 3261	The Moon phase indicator of this watch indicates the
	current phase of the Moon as shown below. It is based on
	the view of the left side of the moon at meridian transit
	from the northern hemisphere of the Earth. If the
	appearance of the Moon phase indicator is reversed from
	the actual Moon as viewed from your location, you can
	use the procedure under “To reverse the displayed Moon
Moon Phase Indicator	phase” (page E-67) to change the indicator.

Moon Data

The Moon phase and Moon age information that appears first when you enter the Moon Data Mode shows the data at noon for your currently selected Home City on the current date, according to the Timekeeping Mode. After that you can specify another date to view data.

•If the Moon data is not correct, check your Timekeeping Mode settings and correct them if necessary.

•The Moon phase is displayed in the Timekeeping Mode, and the Moon Data Mode.

•If the Moon phase indicator shows a phase that is a mirror image of the actual moon phase in your area, you can use the procedure under “Reversing the Displayed Moon Phase” (page E-66) to change it.

•Use the Moon Data Screen to specify the Moon Data date. You can use E(+) to change the displayed date in one-day increments. Pressing Ewill display the year of the displayed date.
