Nav Master combines personal training and
navigation functions into one compact wrist
computer. It is among the world’s smallest of its
kind and yet fully water resistance. It can withstand
immersion in 30 meters of water. The GPS
navigation function locates and tracks your position
wherever you go. Nav Master is powered by a
highly sensitive chip that tracks your position even
at weak signal condition. It can be adopted for
various kinds of outdoor activities such as Jogging,
Running, Biking, Hiking, Skiing, Sailing, Hunting,
etc.

This package comes with a digitally coded Heart
Rate Monitor (HRM) chest strap and a USB
dedicated cable. The HRM listens to your physical
condition and gives you warning instantly when
you do exercise. This package comes with a
dedicated USB cable. This USB clip cable is used
for fast battery charging and data transfer between
your Nav Master and PC in a snap. Data transfer
is done by a PC software, GPS Master. It assists
you with workout analysis, route planning and
training summary reporting. It is a helpful partner
that accompanies you to explore your physical
limits and beyond.

A. Introduction: Warnings and Cautions
WARNING !
CAUTION
 Be sure that you fully understand the functions and limitations of this product
before using it.
 This product can only locate positions in
an outdoor environment or open area.
The more open the area is, the more
accurate and faster information it can
collect to locate the position.
 The performance of this product, like most Global Positioning System
equipment, depends on the satellites operated by the government of the
United States. The satellite system may be subject to change which could affect
the accuracy and performance of this product and all GPS equipment.
 This product is an assistant device for navigation. It is NOT a substitute for
getting the navigating information from charts, maps, observations and
experienced navigators. DO NOT use this product for navigation that requires
precise navigation or is used for vital matters.
 This Watch and Chest Strap is a supplementary device for measuring heart
rate; it is NOT a substitute for medical devices. You should periodically compare
the heart rate readings acquired by this watch and Chest Strap with the
readings from a doctor.
 Consult a doctor or trainer before setting your Upper and Lower heart rate
limits.
 This product, like most electronic or magnetic devices, may interfere with the
pacemaker. Therefore, it is safe for patients with pacemakers to check with
their doctors before using this product.
 In case of doubt about the directions and positions of the way of navigation,
consult the park administration office before starting the navigation.
 DO NOT expose your watch to extreme conditions.
 DO NOT use this Watch and Chest Strap for commercial or professional
purposes.
 DO NOT charge or connect the unit with the USB clip when it is wet. Wipe dry

C. Heart rate Monitor Function: Strap Pairing
Strap Pairing
Every Chest Strap (HRM) is assigned a unique ID when it was manufactured in the factory. The watch
has to be paired up with it before use. This is to avoid interference with other users who are using the same
equipment. Pairing has been done in the factory. Should you replace the HRM with a new one, you have to pair
the new strap again.
To do the pairing, Hold [M] to go to Menu --> HRM--> Pairing. Then touch and hold the 2 conductive pads on
the Chest Strap for a few seconds. If the pairing is successful, the message “DONE!” will be displayed on the
watch.

C. Charge the Battery
The watch has a built-in rechargeable lithium polymer battery. Charge it for at least 3 hours when it is
going to be used for the first time. When the battery is empty, the charging cycle will be completed in less than 2
hours. When the battery is not empty, the charging time will be shorter.The performance of the battery with a
single charge depends upon its usage. If the GPS is not activated, it can run for approximately one year. This
rechargeable battery is good for at least 500 charging cycles. Battery gauge function is provided. The
approximate remaining time left, when working with GPS, is calculated by pushing the [V] button once in the
TIME mode. This can only serve as a rough estimation. The actual life may vary with change of the operating
conditions. If the battery level is nearly empty, GPS function will be disabled automatically. At this stage, the
watch can still run for another 2 weeks with normal time keeping functions.
To charge the battery :
1) Align the clip guide and pins with the notch and contacts at the bottom of the watch
2) Make sure the clip is secured
3) Plug the other end of the USB cable into one of the PC’s USB connectors

D-01
Waypoint
Waypoints are a set of coordinates that identify points in a physical space. For the purpose of terrestrial
navigation, these coordinates usually include longitude and latitude, and sometimes altitude. The Waypoint
name is limited to 10 characters long. It can be named or renamed in the GPS Master. Renaming can be done
easily by just kicking and dragging on the waypoint names.
Path
Path is a collection of waypoints. It can be treated independently as scattered waypoints; or linked in sequential
order (either forward or backward). Linked waypoints form a PATH (or route). Nav Master has 10 Paths. Each
path has a maximum of 99 waypoints. Paths can be created by Lap-To-Waypoint function (Smart Lap). Or they
can be created by GE (Google Earth) or GMaps (Google Maps) then they are transferred to the watch through
the GPS Master. The Path name can be 32 characters long.
Workout log
After workout or navigation has started, Nav Master collects all data into the Workout log. The sampling
interval is controlled by the values in the TrackLog setting. Workout logs contain: starting time and date,
workout summary, lap details, speed, distance, HR and track data.
Pace
PACE is commonly used by runners to estimate the time required to go to a destination. It is defined as the
elapsed time needed per Km / Mile. It is another interpretation of speed but in reverse unit. The unit of PACE is
specified in Menu-->Settings-->System-->Units-->Dst/Spd.
E.g. when the unit is Km and PACE is 6,it means that you are running at 6 minutes per Kilometer. It is equivalent
to 60/6 => 10 Km/H. When the value of PACE is smaller, it means that you are running faster.
Compass bearing
Compass bearing is equivalent to azimuth bearing. An azimuth bearing uses all 360° of a compass to indicate
direction. The compass is labeled clockwise with 0° as North, 90° as East, 180° as South, and 270° as West,
so a bearing of 42° would be northeast and a bearing of 200° would be southwest, and so on.

Lap-By-Distance (LBD)
Create a lap after the preset lap distance has reached
Lap-To-Waypoint (L2WP)
Create a waypoint at the end of a selected path whenever a lap is marked.
AGPS ( Optional function )
AGPS stands for Assisted GPS, is a method which shortens the time for "fixing"GPS satellites signal. Also, it aids the
watch to perform a faster GPS positioning calculation under a weak signal environment.
The watch AGPS function is always on.
AGPS does have expiry. The expiry can be checked by Menu > GPS > AGPS.
AGPS data will be sent to watch when connecting to GPS Master. The updating process will take around 30 seconds once
the watch is un-plugged. During this period, GPS function is not available. Once finished, the expire date will be updated.
Cold Start
When GPS has been suspended for a long time, Satellite data collected earlier are not valid anymore. It takes about 30
seconds to collect sufficient satellite data to locate your position. This is known as cold start.
Hot Start
When GPS has been terminated for only a short period of time before re-starting, satellite data is still valid. It takes only a
few seconds to locate your position. This is known as Hot start.
GPS Master
GPS Master is a PC application software written to work with the Nav Master watch. Workout log and paths can be
downloaded / uploaded easily via the USB cable. GPS Master provides a much better means for workout analysis, path
creation and manipulation.
%EMHR
%EMHR = percentage of Heart Rate (HR) with respect to the Estimated Maximum Heart Rate.
Estimated maximum HR is calculated as 220 – your age
Target HR Zone (Target Zone)
The region of HR is what you would like to set your highest and lowest HR limits to be during exercise.

E. Workout Mode
E-01
The Workout mode records and displays your current performance. You can keep records
of and review your performance while you are running or navigating in the wilderness. The
workout mode shows speed, distance traveled, workout time from the start, heart rate and
other useful data regarding your current workout. It keeps records of speed, heart rate and
altitude for you to view on a PC graphically.
The Workout mode can work with the Navigation mode simultaneously. Start, stop, lap,
GPS shortcut operations are common to both modes. Performing these actions in either of
these modes has the same effect.
About the Workout Mode
The watch offers 5 activity profiles (defaults are Running, Cycling, Hiking, Sailing and User).
Name editing of these profiles can only be done in the PC application software. Text editing
is quite a painful task if it is done by a watch which only has 4 buttons. Each profile has 3
views (or screens). Each view has 3 data fields. Data fields can be selected freely from a
list of fields. This allows you to view selected fields on your own interest. Profile
configuration can also be done through the PC software quickly. You can store as many
profiles as you want in the PC. Its massive storage capacity is virtually no limit to the
number of possible profile combinations that you can think of.

How to turn ON the GPS manually:
If GPS receiver has been stopped for a long time, say more than 2
hours, it is recommended to start the GPS manually, especially
when you want to have track logging done at the beginning of
workout. It is because the GPS cold start time is long. Usually it
takes approximate 30 seconds. During the cold start period, track
information is not available. You should have the GPS position
updated in advance. To do this , you can do either of the
followings:
a) Hold [M] > Menu > GPS > GPS ON or OFF (turn GPS ON); or
Simply hold [V] for 2 seconds at Workout / Navigation modes to
toggle GPS either ON or OFF.
b) Hold [M] > Menu> GPS> Timeout
Either 5 or 30 minutes can be chosen. When GPS is lost and
30 minutes timeout is selected, the watch will try to re-locate its
position via satellites in 30 minutes.
GPS status indicator
- When GPS is collecting satellite information, an “ANTENNA”
icon is flashing at the top left for most of the workout views.
- If the GPS has a 2D location located, a “GPS fixed”
message will pop-up and it will last for a few seconds. An Icon
at the top left is as shown here.
- If more than one satellite are captured, the GPS has a 3D
location located. An Icon will be like this.
- If the GPS loses contact with satellites and cannot fix its
position, a pop- up “GPS Lost” message will appear. It stays on
the LCD until a button is pressed.

E. Workout Mode - Smart Lap
E-06
Smart Lap is a concept of marking laps or waypoints automatically. You can make use of Smart Lap to achieve the
following functions:
Lap-By-Distance (LBD): Hold [M] to enter the Menu>Workout>SmartLap>ByDist
When this function is turned ON, you can specify a fixed distance such that a new lap is marked
automatically whenever the lap distance is reached with the preset target. You just focus on your workout. It is no
need for you to push the lap button anymore. You are free to mark any new laps manually in between the Lap-ByDistance period.
* When the Alert function is switched ON, a single beep will sound once when a new lap is marked.
Lap-To-Waypoint (L2WP) : Hole [M] to enter the Menu>Workout>SmartLap>”Lap->WP”
This is a very useful feature to create a PATH by the watch alone. One of the 10 PATHs has to be dedicated
for this purpose. This path is specified in the Lap->WP setting screen. If this function is turned ON, the selected
path is cleared at the beginning of Workout/Navigation. After that, whenever a new lap is created, disregarding
whether it is added by Lap-By-Distance or by pushing lap button manually, the current location is added as the
latest waypoint of the dedicated path. The number of waypoints allowed is the same as that defined in the regular
paths.
E. Workout Mode - Application example - Backward tracking
E-07
A typical application for this is backward tracking. If you are going to explore the wilderness without planning and
want to return on the same path, you may:
- Set LBD to, say 200 meters, and turn it ON: Hold [M] to enter Menu>Workout>SmartLap>ByDist>[ON,
200].
Remember that the maximum number of waypoints for a path is limited to 99. Set minimum LBD distance
accordingly and yet it will not exceed the limit. Waypoints beyond the path limit are ignored.
- Set L2WP path to Path9, and turn it ON: Hold
Path9]
[M]
to enter Menu>Workout>SmartLap>" Lap->WP">[ON,
- Start Workout/Navigation trip: Navigation [S/S]
- If you want to stop and return, then press [S/S] to stop and hold [L/R] to reset and then you are ready to return
on the same path.
- Turn OFF L2WP: Hold [M]
to enter Menu>Workout>SmartLap>"Lap->WP”>[OFF]
- Select Path9 as the current path for navigation. Hold [M] to enter Menu>Navigation>SelPath>Path9
- Set navigation mode to backward. Hold [M]
to enter Menu>Navigation>NavMode>Backward
- On the Navigation-Goto screen, select the last waypoint of Path9 as the current waypoint
- Start Navigation, follow the Heading Pointer. The watch will guide you from the last waypoint to the starting
point precisely.
E. Workout Mode - Application example - Triathlon Race
E-08
Tips for using the watch at Triathlon Race:
1) Start ( before start to swim): Secures the watch firmly around goggles straps, with watch antenna
direction pointing to the sky.
Antenna
Direction
Antenna
location
2) At T1 (swim to bike): take off the watch from the goggles and wear it around wrist, or mount it on top
of bike mount
3) At T2 (bike to run): after putting on the watch around wrist, exit (not stop) Workout Mode and reenter it by pressing key [M]: Workout Mode -> Navigation -> Compass -> Time -> Workout Mode
The reason for doing this is that our watch has Biking and Running Modes. They have different methods
for speed / distance calculations. Re-entry Workout Mode can reset the Mode to Running.

F. Navigation Function
F- 01
The Navigation mode has 2 screens: Navigation and Goto screens. Navigation screen gives you all the
information you need when you are navigating to a waypoint. Goto screen allows you to pick a waypoint from
the current path.
Introduction
Nav Master is able to keep 10 paths simultaneously. But you can work on a single path at a time. This is known
as the current path. To select the current path: Menu > Navigation > SelPath. Each path has a maximum of
99 waypoints. Waypoints, in a path, may or may not have relationship with one another. When they have no
relationship, this path is just a collection of scattered waypoints. Waypoints can be linked sequentially to form
a route. You can navigate up or down a route until the first or last waypoint has been reached. Select you
navigation mode before navigation
Navigation modes
There are 3 navigation modes: Waypoint, Forward, and Backward modes. You can pick your desired mode
with this key sequence – Menu > Navigation > Nav Mode.
Waypoint mode
The active waypoint is the destination. Select this mode if you want to go to the individual waypoints in the
current path. Then, pick the active waypoint on the Goto screen. This active waypoint is actually the
destination.
Forward mode
The last waypoint is the destination. Select this mode if you want to navigate from the first waypoint to the last
one in the current path. Pick the nearest waypoint as the active waypoint on the Goto screen before you start.
When the active waypoint is reached, it will navigate to the next waypoint along the path. This repeats until
the destination (last waypoint) is reached.
F. Navigation Function
F-02
Backward mode
The first waypoint is the destination. Select this mode when you want to navigate along the path in reverse
order. For example: from the last waypoint to the first one along the current path. Pick the nearest waypoint
on the Goto screen before you start. If the active waypoint is reached, it will navigate you to the previous
waypoint along the path. This repeats until the destination (first waypoint) is reached.
Set Waypoint radius
You are regarded as arrival at the active waypoint when you fall into the region of the waypoint within the
radius set in the WP Radius setting. It can be adjusted in Menu > Navigation > WP Radius. The Default is 30
meters (100 ft). The range is 10m~200m.

Follow the heading pointer
Once GPS has been fixed, the heading pointer starts to
work. Make sure that the electronic compass has been
calibrated properly (See compass calibration details in the
System Setting chapter) and the watch is maintained at
horizontal position. Tilting away from the horizontal position
will affect the accuracy of the heading pointer. When
everything is properly set, the pointer always points to the
active waypoint.
Your current speed and distance to the active waypoint are
shown at the top right of Navigation screen. Time of Day,
Workout Time, Distance to Destination, Estimated Time to
Destination, and Current HR are scrolling out once at a time
at the bottom line. When there is no HR datum, it will not be
shown at all and this part will be skipped.
When you are approaching to the WP region of the active
waypoint within the preset radius, 3 beep tones will be
heard. The beep tones will be suppressed when the Key
Tone setting is turned OFF. If you are navigating with
Forward / Backward mode, it directs you to the next
waypoint automatically. This process repeats until you arrive
at the final destination.
