Using Bearing Memory
Bearing Memory lets you temporarily store and display a direction
reading so you can use it as a reference as you take subsequent digital
compass readings. The Bearing Memory screen displays the direction
angle for the stored reading, along with a pointer that indicates the stored
reading.
When you take digital compass readings while the Bearing Memory
screen is displayed, the direction angle of the current digital compass
reading (as read from the 12 o’clock position of the watch) and the stored
Bearing Memory direction reading will both be shown.

Setting a map and fi
Having an idea of your current location is important when mountain climbing or hiking. To do this, you
need to “set the map”, which means to align the map so the directions indicated on it are aligned with the
actual directions of your location. Basically what you are doing is aligning north on the map with north as
indicated by the watch.
• Note that map reading skills and experience are required to determine your current location and
destination on a map.

Digital Compass Precautions
Magnetic North and True North
The northerly direction can be expressed either as magnetic north or true
north, which are different from each other. Also, it is important to keep in mind
that magnetic north moves over time.
• Magnetic north is the north that is indicated by the needle of a compass.
• True north, which is the location of the North Pole of the Earth’s axis, is the
north that is normally indicated on maps.
• The difference between magnetic north and true north is called the
“declination”. The closer you get to the North Pole, the greater the
declination angle.
Location
• Taking a direction reading when you are near a source of strong magnetism can cause large errors in
readings. Because of this, you should avoid taking direction readings while in the vicinity of the
following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal
(metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal
computers, washing machines, freezers, etc.)
• Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is
because the metal framework of such structures picks up magnetism from appliances, etc.
• Accurate direction readings are impossible while in a train, boat, air plane, etc.

Storage
• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of
this, you should store the watch away from magnets or any other sources of strong magnetism,
including: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors,
lockers, etc.), and household appliances (TVs, personal computers, washing machines, freezers, etc.)
• Whenever you suspect that the watch may have become magnetized, perform the procedure under “To
perform bidirectional calibration” (page E-23).

Specifying Temperature, Barometric Pressure, and Altitude Display Units
Use the procedure below to specify the temperature, barometric pressure, and altitude display units to be
used in the Barometer/Thermometer Mode and the Altimeter Mode.
Important!
• When
TYO
(Tokyo) is selected as the Home City, the altitude unit is set automatically to meters (
m
), the
barometric pressure unit to hectopascals (
hPa
), and the temperature unit to Celsius (
°C
). These
settings cannot be changed.
To specify temperature, barometric pressure, and altitude display units
1. In the Timekeeping Mode, hold down
E
for at least two seconds.

Taking Barometric Pressure and Temperature Readings
This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature
sensor to measure temperature.
