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satellite data is no longer valid.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 V System V Units V General.
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 M to 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.
