Configuring the Watch for First Use
Now that you’ve become familiar with the layout and functions of the
buttons, as well as the way the modes are arranged on the watch, it
is time to set the watch up for use. There are a few essential set-
tings that must be made, such as time and maximum heart rate.
Then, you may want to set up your target zones. Finally, you can
explore the more advanced features the watch has to offer.
Basic settings
Before you use your Performance Monitor during a workout, make
sure that you’ve set the following parameters correctly:
1. Set the Time of Day.For detailed setting instructions, refer to
page 22 of this manual. If you are using this watch with the
Speed + Distance Sensor, your time settings will be corrected to
follow UTC time, and corrected for drift over time.
2. Enter you Maximum Heart Rate (HR
MAX
). Go to Configure Mode,
select “HRM Settings” and then “Max HR.” This setting is used to
determine your five preset heart rate target zones. If you need help
navigating through Configure mode, refer to the section for that
mode on page 43. There are many methods to estimate your maxi-
mum heart rate. One widely used age-based method is 220 – age;
use this formula if you don’t know your maximum heart rate.
3. Select your desired length units.Again, in Configure Mode,
select “Watch Settings,” then select “Length Units.” This setting
fore, if possible, move away from other users of Timex® Sensors if
this error occurs.
The watch will search for the “missing” device for one minute
after this message appears on the display. See “Viewing Perfor-
mance Data” on page 14 for the procedure on reestablishing a link
to this Sensor if the watch does not automatically find it within
the one minute period.
NOISY DATA FROM HRM (GPS) – The watch is having difficulty
receiving data from the indicated sensor due to radio interference.
If possible, try to move away from any potential sources of inter-
ference such as TVs, monitors or motorized devices.
The watch will continue to track the Sensor for about thirty seconds
after this message has appeared on the display; if the interference
condition persists, the watch will stop tracking data from the Sen-
sor. See “Viewing Performance Data” on page 14 for the proce-
dure on reestablishing a link to this Sensor if the interference con-
dition is not corrected within the thirty second period.
FATAL GPS ERROR (Speed + Distance) – The Speed + Distance
Sensor has encountered a severe internal error. Contact Timex
Customer Service.
