Introduction
Thank you very much for purchasing the “TRUME".
Make sure you read the manual supplied to use this product correctly.
This product is not intended for taking measurements that requires professional precision. Measurement
function readings are intended for general reference only.
This product can identify the current time zone by receiving GPS satellite signals and adjust it to the correct local time.
Also, the Automatic Time Reception feature is constantly automatically correcting the time.
*However, you need to set Daylight Saving Time (DST) manually.
The watch's built-in sensors allow you to check field information such as altitude, vertical speed, direction, barometric
pressure, and distance.
The watch continues to operate when it is charged by light. This watch is an environmentally friendly product that
generates electricity through natural resources and does not require regular battery replacement.
The following provides a quick introduction on using this product.
To select the item you want to measure, press and release the A button to move the mode hand to the mode you want to
measure, such as ALT (altitude) or BAR (barometric pressure). You can then start or stop measuring by simply
pressing and releasing the C button.

Before Use
For example, if you have been traveling abroad.
The watch has a built-in GPS satellite signal reception system called "SATELLITELINK" that receives a GPS signal by
one action and automatically enters the current time zone when you leave the airport at your destination.
After dropping off your luggage at the hotel, you can go out and explore the city.
If you do not know your way around the city, check the direction in COM (direction) mode. The center hand points
North while vibrating slightly like a real magnetic compass.
Hold down the B button for at least three seconds in COM mode to register the location of the hotel as the base point. If
you get lost while out exploring, press the C button for at least three seconds. You can use the hands on the watch to
check the direction and distance to the hotel (Waypoint feature).
Many people enjoy heading to the countryside on their holidays.
When you are planning such a trip, wear the watch when you go out. You can check the altitude, pressure, or direction
at the current location with two actions at anytime. The ability to check the measurements for a variety of sensors by
simply glancing at the hands of your watch allows you to feel closer to nature.

Information on the Watch's Mechanics
Adjusting the time by receiving signals from GPS satellites
GPS satellites are equipped with high-precision atomic clocks with a margin of error of one second every 100,000
years. Signals sent from the GPS satellite to earth contain "time information" based on the atomic clock.
With the touch of a button, this product receives signals from the GPS satellite and adjusts the time according to the
following information.
❏ Received from one satellite:
Exact time and date based on the atomic clock
❏ Received from multiple satellites (at least four):
Time zone information for your current location
*Unlike navigation devices, this product is not designed to constantly receive GPS satellite signals.

MB73 (TR-MB7) User’s Guide
Before Use
Note:
About GPS satellites
The satellites are controlled by the United States Department of Defense and orbit at an altitude of 20,000 km.
Originally, these satellites were designed for military purposes, but now some of the information they send is for consumer
use and is used in a variety of devices such as car navigation systems and smart phones.
Supports the Quasi-Zenith Satellite System
This product supports the first Quasi-Zenith Satellite System (QZSS).
The QZSS is a system of satellites that passes directly over Japan and sends positioning signals that are very similar to current
GPS signals. This allows signals to be sent to wider areas of Japan that were previously trouble spots, such as mountainous
regions, or areas with a high density of skyscrapers.
Coordinated Universal Time (UTC) and time zones
UTC is a universal, standardized time set by international accord. This is used as the official time when time is recorded
around the world.
Around the world, countries and regions use common standard times based on Coordinated universal time (UTC).
Standard times are determined by specific countries and regions, and a region that uses the same standard time is
called a time zone.
* The time zone for each region may change depending on the circumstances of the country or region.
Daylight Saving Time (DST)
Daylight Saving Time (DST) is a system that advances standard time by one hour (or another specific time) during
long periods of daylight, normally during summer. Also known as summer time.
This system is used in approximately 80 countries around the world, mainly in Europe and the United States, in
countries at a high latitude and long daylight hours in the summer.
* The way DST is implemented may change depending on the circumstances of the country or region. Also, the period during which
this is applied varies by country/region.

The watch is a pressure altimeter that calculates altitude from the atmospheric pressure. By using the atmospheric
pressure at the current location, the relative altitude is calculated based on the relationship between the altitude and the
atmospheric pressure for International Standard Air (ISA) determined by the International Civil Aviation
Organization (ICAO).

Relative
altitude
901 hPa
955 hPa

hPa
1,000 m
500 m
0 m
Note:
The relative altitude is calculated from the atmospheric pressure, temperature, and the sea level pressure for the
international standard atmosphere at your current location.
❏ Atmospheric pressure at current location: Value measured with built-in pressure sensor
❏ Temperature at current location: 15 °C
❏ Sea level pressure: 1,013.25 hPa
If the atmospheric pressure changes due to weather conditions or the temperature at the measurement location, the
actual altitude and the relative altitude will not match. Therefore, the watch comes with a feature to calibrate the
deviation in the relative altitude.
The calibration value is added to the relative altitude and this altitude is displayed on the watch.

About the altitude calibration feature
By setting the actual altitude at a location where you already know the altitude, the difference between the relative
altitude measured at that location and the actual altitude is stored in the watch as the correction value by the altitude
calibration feature.
At the time of purchase, the calibration value is set to 0.

Notes on altitude measurements
❏ This product is not intended for taking measurements that requires professional precision. Measurement
function readings are intended for general reference only.
❏ The altitude displayed by this product is calculated using atmospheric pressure data. When measuring in ALT
mode, altitude information acquired by receiving GPS satellite signals is not used.
❏ Weather conditions change over time. Whenever possible, calibrate the altitude before measuring.
❏ The altitude display range is 0 to 9,999 m. The altitude is displayed as 0 when it is less than 0 m.
Notes on the effects of temperature
Measurement results may differ due to the effects of changes in temperature.

Notes and Mechanism for Variometer Feature
Mechanism for variometer
The watch comes with a feature known as a variometer that can represent a glider or an airplane.
The watch calculates the vertical speed by detecting changes in the altitude from changes in the barometric pressure
measured using the built-in pressure sensor. The small second hand on the watch indicates the vertical speed in units
of meters per second (m/s).
Climbing
Climbing
+2 m/s
-2 m/s

Note:
❏ Normally, a variometer is an instrument that indicates the vertical speed of an airplane. This is also known as a rate of
climb and descent indicator (RCDI), rate-of-climb indicator, vertical speed indicator (VSI), or vertical velocity
indicator (VVI). Pilots maneuver their aircraft by checking the rate of climb or descent indicated by this instrument.
❏ Vertical speed refers to the rate of change in altitude according to the time at which the aircraft climbs/descends.
Depending on the country or the type of aircraft, this value is indicated in feet per minute (ft/m) or meters per second
(m/s).
Notes on measuring vertical speed
❏ This product is not intended for taking measurements that requires professional precision. When using the
measurement feature, make decisions and take actions at your own risk.
❏ Do not use the watch when flying gliders, paragliding, and so on.
Notes on the effects of barometric pressure adjustments
This product calculates the vertical speed using the pressure sensor. When you are in an environment in which the
barometric pressure has been adjusted, such as on a passenger aircraft, the vertical speed measurements differ from the
actual vertical speed.
Notes on the effects of weather conditions
Measurement results may differ due to the effects of weather conditions.

About the Waypoint Feature
The Waypoint feature is a feature that allows you to return to the location (base point) registered in advance from your
current location. You can check the direction of the base point and the linear distance. You can also change the range
(maximum value) for the linear distance displayed in three stages.
For example, when using the Waypoint feature when you're on holiday to register your hotel as the base point (1) and
returning to the hotel from a tourist spot (2) near the hotel, you can check the direction to the hotel (3) and the linear
distance (4).

❏ Use the Waypoint feature in a location suitable for receiving GPS satellite signals.
U “Locations Suitable for Receiving Signals from GPS Satellites” on page 35
When using the watch in a location where it is hard to receive signals from GPS satellites, it may not be possible to
measure the exact linear distance and direction to the base point.
❏ The Waypoint feature differs from the general navigation feature. You cannot set the base point using maps, addresses,
and so on. Also, it cannot guide you along routes.
❏ You can change the range (maximum value) for the linear distance displayed in three stages. Set the Distance Range
