Set the Backlight always on feature On or Off. With always on chosen the watch display will be illuminated throughout your training session. The backlight setting will default back to Off after you finish your training session. Please note that the always on setting will drain your battery much faster than the default setting.

Pool length:

When using the Swimming/Pool swimming profile, it’s important that you choose the correct pool length, as it affects pace, distance and stroke calculation, as well as your SWOLF score. Press OK to access the Pool length setting and change the previously set pool length if necessary. The default lengths are 25 meters, 50 meters and 25 yards, but you can also set it manually to a custom length. The minimum length that can be chosen is 20 meters/yards.

Pool length setting is only available in the pre-training mode from the quick menu.

If you have paired a third-party cycling power sensor with your watch, you can calibrate the sensor from the quick menu. First, choose one of the cycling sport profiles and wake up the transmitters by rotating the cranks. Then choose Calibrate power sensor from the quick menu and follow the on-screen instructions to calibrate your sensor. For calibration instructions specific to your power sensor, see the manufacturer's instructions.

There are two ways to manually calibrate your stride sensor via the quick menu. Choose one of the running sport profiles and then choose Calibrate stride sensor > Calibrate by running or Calibration factor.

• Calibrate by running: Start the training session and run a distance you know. The distance has to be more than 400 meters. When you have ran the distance, press OK to take a lap. Set the actual distance you have ran and press OK. The calibration factor is updated.
  Please note that interval timer cannot used during the calibration. If you have set the interval timer on, the watch will ask you to turn it off to enable manual stride sensor calibration. You can turn the timer on from the pause mode quick menu after calibration.
• Calibration factor: Set the calibration factor manually if you know the factor which gives you accurate distance.

For detailed instructions on manual and automatic calibration of a stride sensor, see Calibrating a Polar stride sensor with Vantage V/Vantage M.

This option is shown only if you have paired a stride sensor with your watch.
