FT4 body measurement features:
• Automatic age-based target zone – bpm / %
To help you train safely and effectively, the training computer determines your heart rate target zone limits automatically according to your age-based maximum heart rate (220 minus age). The limits are determined either in beats per minute (bpm) or as a percentage (%) of your maximum heart rate. See also Manual target zone.
• Average and maximum heart rate of training
• Heart rate – bpm / %
Heart rate is the measurement of the work your heart does. Heart rate can be expressed as the number of beats per minute (bpm) or as a percentage (%) of your maximum heart rate.
• HR-based target zones with visual and audible alarm
You can define your target zones for a training session based on heart rate to help define the right intensity. When you are out of the preset zones, the training computer will give a visual and audible alarm.
• HRmax
This allows the user to set an upper maximum heart rate for the activity, with visual and audible alarms to notify when heart rate goes above this rate.
• Manual target zone – bpm / %
This feature enables you to define the target zone as you want and is suitable for your training. You can set the target zone for your training as beats per minute (bpm) or as a percentage of your maximum heart rate.
• Polar® OwnCal® - calorie expenditure
Polar OwnCal® calculates the number of kilocalories expended during training. This feature allows you to follow the kilocalories expended during one training session and cumulative kilocalories expended during several training sessions.
• Polar OwnCode® (5kHz) – coded transmission
Coded WearLink®+ textile transmitter automatically locks in a code to transmit your heart rate to the training computer. The training computer picks up your heart rate from your transmitter only. Coding prevents interference from other training computers.
FT4 recording features:
• Totals
Totals includes your training data starting from the last reset enabling you to follow your long-term training.
• Training files
Summaries of the last 10 training sessions are stored for later recall.
FT4 training features:
• Graphical target zone indicator
This feature points out graphically on the display the zone you are in during a training session helping you to stay on the desired intensity zone.
• HeartTouch – button-free operation of wrist unit
When HeartTouch is on, different training information during training can be accessed without pressing buttons, for instance, when gloves make pressing buttons difficult, by bringing your training computer close to your transmitter.
FT4 watch features:
• Backlight
