Compass bearing is a 360˚ direction indicator. 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.
Lap-By-Distance Creates a lap after the preset lap distance
has been reached.
Lap-To-Waypoint Creates a waypoint at the end of selected
path whenever a lap is marked.
Cold Start If GPS has been off for over 2 hours, the
satellite data is no longer valid. It takes about 30 seconds
to acquire sufcient new data and x your location.
Hot Start If GPS has been off for a short time and you
re-start; satellite data is still valid. It takes a few seconds to
x your location.
"GPSMaster" is application software written to work with
this watch. Workout log and paths can be downloaded /
uploaded via the USB cable. GPSMaster provides a much
better means for workout analysis, path creation and
manipulation.
%EMHR is the percentage of the Estimated Maximum Heart
Rate. EMHR is calculated as 220 minus your age.
Target HR Zone is the region in which you would like your
Heart Rate to be during exercise.
C. Definitions / Glossary
Waypoints are sets of coordinates that identify a point
in physical space. These coordinates usually include
longitude and latitude, and sometimes altitude.
Waypoint names are limited to 10 characters and are
named or renamed in GPSMaster.
Path is a collection of waypoints. It can be treated
independently as scattered waypoints; or linked in
order- either forward or backward. Linked waypoints
form a PATH. This watch supports 10 Paths. Each path
has 99 waypoints maximum. Paths can be created in the
Lap-To-Waypoint function. Or created by GE (Goggle
Earth) / GMaps (Google Maps); then imported through
GPSMaster. A path name can be 32 characters long.
Workout logs are records that contain: starting time /
date, workout summary, lap details, speed, distance, HR
and track data. The sampling interval is controlled by the
value established in TrackLog setting.
Pace is an estimated rate of travel. It is based on the
elapsed time needed per Km / Mile. The unit of PACE is
specified in Menu Settings VSystem VUnits VGeneral.
If the unit is Mile and PACE -reads 6 then you are
moving at 6 minutes per Mile.

D. Charge the Battery
The watch has a built-in rechargeable lithium
polymer battery. Charge it for at least 3
hours before first use. When exhausted,
the battery charges completely in less than
2 hours. The life of a single charge depends
upon usage: If the GPS is not activated, it will
last up to a year. If GPS is left ON, it will last
about 8.5 hours. The battery is good for at
least 500 charges. Even a 15 minute charge
will keep GPS running up to 1.5 hours.
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 the USB cable into the computer
See photo on the right.
Battery energy level. In TIME MODE press V
or when using the GPS, press Mto view
the approximate time left. This is a rough
estimate. Actual life will vary as operating
conditions change. When the battery nears
empty, GPS and backlight will be disabled.
However, normal time keeping will continue
to run for another 2 weeks.

F. Warnings and Cautions
WARNING:
• Make sure that you fully understand the functions and
limitations before use.
• Performance depends upon United States satellites. This
satellite system may make changes that could affect
accuracy and performance.
• This product is an assistant device for navigation, and it is
NOT a substitute for getting the navigating information
from charts, maps, observations or an experienced
guide. DO NOT use this product for navigation that
requires precise vital locations.
• The Watch / Chest Strap measures heart rate and is NOT
a substitute for medical devices.
• Consult a doctor or trainer before setting your Upper and
Lower heart rate limits.
• Like most electronic or magnetic devices, it may interfere
with pacemakers. Although safe for patients with
pacemakers, be sure check with a doctor before using.
• If you have doubts about the directions and location of a
route, consult a reliable source.
• DO NOT use this Watch and Chest Strap for commercial
or professional purposes.
• DO NOT charge or connect the unit when it is wet.

CAUTION:
• The GPS only works in an open air environment.
The more open the area, the more accurate is the
information, and the faster it is to obtain your first
position.
• The GPS data is not valid until the receiver is nished
acquiring satellite data.
• DO NOT get lotion/sunscreen on the contacts; as they
will insulate the signal.
• DO NOT expose your watch to extreme heat or cold.
• This unit is water resistant and, you can wear it for
swimming. However, the GPS and Heart Rate
functions will not work under water.

watch will try for 30 minutes to re-link to the satellites
When GPS is acquiring satellite information, an “ANTENNA”
icon " " flashes in middle row on left side of most of
the workout views:
If GPS has a 2D location captured, " " will appear.
If more satellites are captured, " " will appear.
If GPS lost the signal and could not x a position, “GPS Lost”
will display until any button is pressed.
Goto screen allows you to pick a waypoint from the
current path.
The watch stores up to 10 paths. You can also work with a
single (current) path.
To select the current path: Menu VNavigation VSelPath.
The waypoints can be linked sequentially to form a route.
You can then navigate up or down the route. Select of
the following navigation modes before you begin
K-01. Navigation Function- Modes:
There are 3 navigation modes:
Waypoint, Forward, and Backward.
Choose a mode – Menu VNavigation VNavMode.
VWaypoint: The active waypoint is the destination. Select
this mode if you want to travel to an individual waypoint
in the current path. Choose the active waypoint in Goto.
This active waypoint is now your destination
VForward: The last waypoint is the destination. Select
this mode if you want to travel from the first to the last
waypoint in a current path. Pick the nearest waypoint as
the active waypoint in Goto before you start. When the
active waypoint is reached, it will navigate to the next
waypoint in the path. This repeats until the destination
is reached
K. The Navigation Function Screens:
Navigation has 2 screens: See illustration on the next page.
Navigation screen provides all the information when
navigating to a waypoint.

VBackward: The first waypoint is the destination. Select
this mode if you want to travel in reverse - from the last
to the first waypoint in current path. Pick the nearest
waypoint in Goto before you start. If the active waypoint
is reached, it will navigate to the previous waypoint in
the path. This repeats until the first waypoint is reached
To Set Waypoint radius: You have "arrived" if you are
within the radius set in WP Radius. You set this radius in
Menu VNavigation VWP Radius. The default is 30m.
The range is 10m to 250m
K-02. How to Navigate
Setup a path and navigation mode as previously explained.
To turn ON the GPS: Hold V. Or, if you want to have
workout logged, press S/S to start. Wait for GPS to x
your location. Meanwhile, to choose the active waypoint,
press Vto switch to Goto screen
To Set an Active Waypoint:
• Press S/S or L/R In Goto to scroll the waypoints on a
current path. The sequence number of a waypoint is
shown in the top right. Path name is in the 2nd line.
Other details are shown consecutively in lines 3 and 4
across 3 separate screens
Screen 1 defines the time, date, and name of
waypoint. The name is restricted to 10 characters and
can be edited in PC Master. Default name “WayptXX” is
