• During exercise, he reaches 171 beats per minute (BPM)
• His calculated MHR = 220 - 30 = 190 BPM
• Percentage of maximum heart rate = 171 / 190 x 100 % = 90 %
• His heart rate has passed the upper limit of 80 % MHR. The watch will alert him that he
slows down to go back to his objective heartbeat zone
How to set the heart rate zone alert
• Press the [D] button in the current time mode or the
countdown timer mode to get to the heart rate mode.
• If you were measuring your heart rate, press the [U]
button to stop heart rate acquisition.
• Hold the [M] button for 2 seconds until ‘ON’ or ‘
OFF’ starts flashing.
• Press the [U] or [D] button to set the value of the
flashing setting.
• Press the [M] button to select between the flashing
settings:
- ‘Zone ON/OFF’: select ‘ON’ to activate heart rate
zone alert.
- ‘Age’: enter your age which will be used to cal-
culate your Maximum Heart Rate.
- ‘Upper Limit in % of MHR’ (flashing in the upper right corner): set your desired upper
limit in percentage of your Maximum Heart Rate. Referring to the example above, this
value would be 80%.
- ‘Lower Limit in % of MHR’ (flashing in the lower right corner): set your desired lower
limit in percentage of your Maximum Heart Rate. Referring to the example above, this
value would be 60%.
- ‘Upper Limit’ (flashing in the upper right corner): allows you to enter directly your upper
limit in Beats Per Minute. If you set your upper limit in BPM, this will automatically
change the setting ‘Upper Limit in % of MHR’.
- ‘Lower Limit’ (flashing in the lower right corner. Note that the hundreds digit is the
double size of the 2 following digits): allows you to enter directly your lower limit in Beats
Per Minute. If you set your lower limit in BPM, this will automatically change the setting
‘Lower Limit in % of MHR’.
• Press the [U] or [D] button to set the value of the flashing setting (hold the buttons to
change set value at a higher speed).
• Hold the [M] button for 2 seconds to save your settings and exit the setting sequence. If
NO keystroke’s been activated for 1 min, the watch automatically exits the setting
sequence.
