Selecting OFF will prevent the Watch from automatically
calculating a recovery heart rate when you stop the chronograph.
You may still manually calculate your recovery rate in Summary
Mode, set to one minute if you select OFF in Configure Mode.
Max heart rate: Enter your Maximum Heart Rate. The Watch
uses this value to calculate the five preset heart rate zones and
serves as a reference for displaying your heart rate as a percent of
your maximum heart rate (PERCENT).
Heart rate display: You can set the Watch to display your
heart rate as either a percentage of your maximum heart rate
(PERCENT) or in beats per minute (BPM). The setting you choose
will determine how your heart rate displays in all other Watch
settings.

TZ Zone and Alert: You may select from one of five preset heart
rate zones (labeled Z1 to Z5) or three custom heart rate zones
(labeled C1 to C3). You may also choose to have the Watch either
alert you or not if your heart rate goes outside of your target zone.

visual indication (an up or down arrow on the Watch display) if
you go above or below your target heart rate zone, and AUDIBLE
combines a warning melody to the visual alert. You will hear an
ascending melody if you go above your zone and a descending
melody if you go below your zone.
Custom Zones: You may set the upper and lower target zone
number or percentage (depending on how you choose to show your
heart rate) for up to three custom heart rate zones, labeled
CUSTOM 1, CUSTOM 2, and CUSTOM 3.
Recovery: This setting determines how the Watch automatically
calculates a recovery heart rate when you stop the chronograph.
