Acumen EON-2027HS, EON-2028HS manual Part

Part II

If you do not have a calibrated MET value or put on a HR transmitter, the watch will only use your pre-set MET value or our default value (Aerobic with Medium Intensity). Please make sure to re-select your exercise type and intensity every time with the procedure mentioned above.

However, if you have already calibrated your own MET value and put on a HR transmitter, the displays of Fluid Loss Setting (Exercise Type and Intensity) will automatically be turned off as the watch will calculate the best MET value for you.

2. When a Lap is finished and the stopwatch is stopped:

-Press MODE/NXT Button D repeatedly to circle around all modes mentioned before, plus the Select TZ Mode and Interval Timer Mode.. You can re-select Target Zone or re-set Interval Timer before start a new lap (if you did that, when you re-start the stopwatch, it begins with a new lap).

The Interval Timers are used for timing your exercise under a selected Target Zone. If you turned on the Interval Timer, you could not re-select the Target Zone and the Select TZ Mode would not show. The Select TZ Mode is displayed until the Interval Timers are finished or turned off.
