Strap Pairing
C. Heart rate Monitor Function: Strap Pairing C-03
Strap Pairing
Every Chest Strap (HRM) is assigned with a unique ID when it was manufactured in factory. 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 should have 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 success, the message “DONE!” will be displayed on the
watch.

C. Charge the Battery C-04
The watch has built-in rechargeable lithium polymer battery. Charge it for at least 3 hours if it is going to be used
for the first time. If battery is empty, charging cycle will be completed in less than 2 hours. If battery is not empty,
charging time will be shorter. A quick 15 minute charging may keep GPS running for around 1.5 hours. Battery life
of a single charge depends upon usage. If GPS is not activated, it can last for around a year. If GPS is ON, battery
life is approximately 8.5 hours. This rechargeable battery is good for at least 500 charging cycles. Battery gas
gauge function is provided. The approximate time left, when working with GPS, is calculated by pushing the [V]
button once in TIME mode. This is only serves as a rough estimation. The actual life may vary as the operating
conditions change. If battery level nearly empty, GPS and backlight functions will be disabled. 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 secure
3) Plug USB cable into any of the PC’s USB connector

D. Getting Start: Glossary
Waypoint
Waypoints are sets of coordinates that identify a point in physical space. For the purposes of terrestrial
navigation, these coordinates usually include longitude and latitude, and sometimes altitude. Waypoint names
are limited to 10 characters long. It can be named or renamed in GPS Master. Renaming can be done easily by
just kick and drag 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 Path. Each
path has 99 waypoints maximum. Paths can be created by Lap-To-Waypoint function. Or they can be created by
GE (Goggle Earth) or GMaps (Google Maps) then imported to watch through GPS Master. Path name can be 32
characters long.
Workout log
After workout/navigation start has started, Nav Master collects all information into a log. The sampling interval
is controlled by value in 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 time required to go to destination. It is defined as the elapsed
time needed per Km / Mile. It is another interpretation of speed but in opposite magnitude. The unit of PACE is
specified in MenuSettingsSystemUnitsGeneral.
.e.g. if unit is Km and PACE is 6 then it means that you are running at 6 minutes per Kilometer. It is equivalent to
60/6 => 10 KmH. If 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 numbered clockwise with north as 0", east 90", south 180", and west 270". So a
bearing of 42" would be northeast and a bearing of 200" would be southwest, and so on.

D. Getting Start: Glossary
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 selected path whenever a lap is marked.
Cold Start
If GPS has been suspended for a long time, Satellite data collected earlier is not valid anymore. It takes about
30 seconds to acquire sufficient satellite data and fix your location. This is known as the cold start.
Hot Start
If GPS has been terminated for only a short period abd re-start, satellite data is still valid. It takes only a few
seconds to fix your location. This is known as the Hot start.
GPS Master
GPS Master is a PC application software which is written to work with 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 HR with respect to the Estimated Maximum Heart Rate. Estimated maximum HR is
calculated as 220 – your age

E. Workout Mode
Workout mode displays your current performance. You can measure and record your
performance as you are running or navigating in the wilderness. The workout mode shows
speed, distance traveled, workout time from start, heart rate and other interesting data
regarding your current workout. It records your track with the speed, heart rate and altitude
that you can view on your PC graphically.
Workout mode works together with the Navigation mode. Start, stop, lap, GPS shortcut
operations are common to both modes. Performing these actions in either of the modes has
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 on the PC application software. Because
text editing is quite a painful task if it is done by a watch which has only 4 buttons. Each
profile has 3 views (or screens). Every view has 3 data fields. Data fields can be selected
freely from a list of fields. This allows users to review selected fields on their own interest.
Profile configuration can also be done through the PC software quickly. You can store as
many profiles as you want in PC. It mass storage device virtually posts no limit on the
number of possible profile combinations that you can think of.

Fixing with
GPS GPS Fixed
How to turn ON GPS manually:
If GPS receiver has been stopped for a long time, say more than 2
hours, it is recommended to start GPS manually. Especially if you
want to have track logging done even at the beginning of workout.
Because GPS cold start time is long. Usually it takes approximate
half a minute. During the cod start period, track information is not
available. you should have the GPS position fixed beforehand. To
do this you can do either of the followings:
a) 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) Menu > GPS > Timeout
It can be chosen either 5 or 30 minutes. If GPS is lost and 30
minutes timeout is selected, the watch will try re-fix satellites for 30
minutes.
GPS status indicator
- When GPS is acquiring satellite information, an “ANTENNA”
icon is flashing on top right for most of the workout views.
- If GPS has a 2D location fixed, “GPS fixed” will pop-up message
will appear for a few seconds. Icon at top left is as shown here.
- If more satellites are captured, GPS has 3D fixed. Icon will be
like this
- If GPS lost satellites and could not fix position, GPS “GPS Lost”
pop- up message will appear. It stays on LCD until any of the
button is pressed.
