Introduction
Thank you for purchasing the GPS watch. This GPS watch is packed with personal Training
features like speed, trip time, laps, etc. GPS can display your current location in an electronic
map. Watch features include 12/24H Time format, Chronograph, World time, 5 daily Alarms, 6
Interval Timers, Run, Run Data, HRM, ALTI and Set modes. This watch can communicate with
a PC to store and review your performance. This watch uses a rechargeable battery that can
be charged through USB port of your PC. It also uses HRM belt with 2.4 GHz technology to
monitor your heart rate for all your HR related information.
Caring for your GPS watch:
Clean your GPS watch with a dampened cloth preferably with mild detergent solution. Wipe dry
using a dry cloth. Do not use chemical cleaners and solvents that may damage plastic
components.
Do not store your GPS watch to prolonged exposure to extreme temperatures as this may
result to permanent damage to your unit.
About GPS:
Global Positioning System (GPS) is a satellite- based navigation system made up of a network
of 24 or more satellites. GPS works best in clear weather condition, anywhere in the world, 24
hours a day. Tall buildings may interfere with GPS accuracy. When 3 satellite signals are
received, the watch will have 2D GPS fixed (Latitude and Longitude). When 4 or more satellite
signals are received, the watch will have 3D GPS Fixed.
Water immersion:
This GPS watch is designed to be water resistant up to 3 ATM. It can resist water pressure up
to 30 meters. After submersion to water, please make sure to wipe dry and air dry the unit
before using or charging.
Caution: This unit is not intended to be used while swimming. Prolonged water submersion
may cause electronic shorting in the unit which may cause minor skin burn or irritation.
Getting Started
Step 1) Know your watch:
Push button location:
Push button Main function:
S1 – Start / Stop / +
S5 – View / Lap
S7 – Mode / Exit
S11 – Light / Set / Save / -

Step 2) Charging the Battery:
Charge the unit for at least 4.0 hours before first use. The length of time for a fully charged
battery will last depending on the actual usage. It is recommended to regularly re-charge your
battery every 1-2 months even if it is not used to maintain good battery condition.
2.1) Plug your USB cable to your PC
2.2) Align the charging clip with the 4 contact pins on the back of the watch.
2.3) Connect the charging clip securely to the watch.
Note: Please thoroughly dry the charging contacts and surrounding area to ensure proper
electrical contact and prevent corrosion.
When the battery is low, it is time to charge the GPS watch. The possible screen when you
charge your watch. Once the battery is full, it will display CHARGE 100% FULL.
Battery low condition:
You cannot turn ON the GPS when the battery is low. The watch will display BATT LOW. The
battery icon will also blink. You need to recharge the battery in order to use the GPS again.
When the battery is almost low and you still perform your exercise, your data may not be saved
if the battery becomes low. Please make sure the battery have enough battery power before
doing your exercise in order not to lose your data.
When the battery level becomes very low, the watch will automatically turn OFF the display
(blank-screen).
Step 3) Configure your watch:
Before using your GPS watch, User can opt to do the following.
3.1) Go to SET mode to set the following parameters: AUTO LAP, TIME, UNIT, USER’ details,
HRM, HRM LINK, NIGHT, CONTRAST, CHIME, ALARM and TIMER.
Step 4) Acquire Satellite signals:
To get the correct time of day and begin using your GPS watch, you have to acquire GPS
signals. It may take few minutes to acquire the satellite signals.
4.1) Go outside to an open area away from tall buildings and trees. Orient the GPS antenna
towards the sky for best reception. The antenna is located at the 6 o’clock position of the
watch.
Note: In order to accurately navigate the GPS, you need to have a good line of sight to the
satellites.
4.2) Stand still and do not begin moving while searching the Satellite signals until the signals
are already received.
4.3) How to turn ON the GPS: While in Time mode, press S1 or S7 to go to RUN mode. The
watch will start locating the satellites “SEARCH GPS”. After receiving the GPS signals, it
will automatically go to RUN mode and the watch will display “GPS GO” while the
“CHRONO” blinks.
Also note that the watch will display the relative signal strength indicator on the upper side
(12H position).
4.4) How to turn OFF the GPS: If you wish to turn OFF the GPS, press and hold S7 in Time
mode for about 3 seconds and the watch will momentarily display GPS OFF and then
return to Time view.

GPS signals and its meaning:
You will hear a beep sound when the watch has received a GPS signal or when the GPS
signal has been lost. LOST GPS signal will also be displayed in the screen.
Step 5) Pair your Heart Rate monitor:
The HRM belt is on standby and ready to send data to your watch. Wear the belt directly on
your skin just below your breastplate. It should be snug enough to stay in place during your
run.
5.1) Push one tab on the strap through the slot in the HRM transmitter.
5.2) Wet both electrodes with a damp cloth on the back of the HRM belt. This will help create a
strong electrical connection between your chest and the HRM transmitter.
5.3) Wrap around the chest belt around your rib cage just below the pectoral muscles and
attach the other end of the strap to the HRM transmitter. The elastic strap should be
adjusted so that it is snug enough so that it will not move during use but not so tight as to
restrict breathing.
5.4) Bring the GPS watch within range of the HRM transmitter (3 meters). The watch will auto
detect the HR belt. The watch will then automatically go to RUN mode. Your Heart rate
information will now be displayed in the watch.
5.5) If the heart rate data does not appear on the watch, or if you have erratic data, follow the
tips below. If the problem persists, you may have to pair the HR belt again.
5.5.1) Make sure the HR belt is snugly fit to your body.
5.5.2) Reapply water or electrode gel to the electrode of the HR belt.
5.5.3) Clean the electrodes from possible contamination that may interfere with heart
rate signals.
5.5.4) Wear a cotton shirt or if possible, wet your cotton shirt. Synthetic fabric that rubs
with your skin may create static electricity and interfere with the heart rate signal.
5.5.5) Move away from strong electromagnetic fields and other wireless sensors which
can interfere with your heart rate sensor. Possible sources of wireless
interference may include high voltage power lines, electric motors, microwave
ovens, cordless phones, and wireless LAN or access points.
Step 6) Go for a Run:
6.1) Using Run mode:

GPS watch troubleshooting guide:
PROBLEM
/
QUESTION SOLUTION/ ANSWER
I cannot get a GPS signal Take your GPS watch outdoors and away from tress and tall buildings. Remain stationary and try acquiring GPS
signal again. Be sure that the antenna is pointing towards
the sky for better signal reception.
Can I reset the watch? You can reset the watch by pressing S1, S5, S7, and S11 together. The date and time will be reset to default
values. You can set it again manually or automatically thru
GPS.
Will my data and personal
settings be lost after watch
reset?
Your data and personal settings are saved in the flash
memory and will not be lost after watch reset.
The battery indicator does
not seem to be accurate Allow your GPS watch to fully discharge and then fully charge it without interruption. It is recommended to
regularly re-charge your battery every 1-2 months even if
it is not used to maintain good battery condition.
My heart rate data seems
inaccurate.
- Make sure the HR belt is snugly fit to your body
- Reapply water or electrode gel to the electrode of the
HR belt
- Clean the electrodes from possible contamination that
may interfere with heart rate signals
- Wear a cotton shirt or if possible, wet your cotton shirt.
Synthetic fabrics that rubs with your skin may create
static electricity and interfere with the heart rate signal
- Move away from strong electromagnetic fields and other
wireless sensors which can interfere with your heart rate
sensor. Possible sources of wireless interference may
include high voltage power lines, electric motors,
microwave ovens, cordless phones, and wireless LAN
or access points.
