+ This face brings 9 customizable interval timers to the sensor watch,
+ to be used as hiit training device and/or for time management techniques.
+
+ - There are 9 interval timer slots, you can cycle through these with the
+ alarm button (short press). For each timer slot, a short "slideshow"
+ displaying the relevant details (like length of each phase - see below)
+ is shown.
+
+ - To start an interval timer, press and hold the alarm button.
+
+ - To pause a running timer, press the alarm button (short press).
+
+ - To completely abort a running timer, press and hold the alarm button.
+
+ - Press and hold the light button to enter settings mode for each interval
+ timer slot.
+
+ - Each interval timer has 1 to 4 phases of customizable length like so:
+ (1) prepare/warum up --> (2) work --> (3) break --> (4) cool down.
+ When setting up or running a timer, each of these phases is displayed by
+ the letters "PR" (prepare), "WO" (work), "BR" (break), "CD" (cool down).
+
+ - Each of these phases is optional, you can set the corresponding
+ minutes and seconds to zero. But at least one phase needs to be set, if
+ you want to use the timer.
+
+ - You can define the number of rounds either only for the work
+ phase and/or for the combination of work + break phase. Let's say you
+ want an interval timer that counts 3 rounds of 30 seconds work,
+ followed by 20 seconds rest:
+ work 30s --> work 30s --> work 30s --> break 20s
+ You can do this by setting 30s for the "WO"rk phase and setting a 3
+ in the lower right hand corner of the work page. The "LAP" indicator
+ lights up at this position, to explain that we are setting laps here.
+ After that, set the "BR"eak phase to 20s and leave the rest as it is.
+
+ - If you want to set up a certain number of "full rounds", consisting
+ of work phase(s) plus breaks, you can do so at the "BR"eak page. The
+ number in the lower right hand corner determines the number of full
+ rounds to be counted. A "-" means, that there is no limit and the
+ timer keeps alternating between work and break phases.
+
+ - This watch face comes with several pre-defined interval timers,
+ suitable for hiit training (timer slots 1 to 4) as well as doing
+ work according to the pomodoro principle (timer slots 5 to 6).
+ Feel free to adjust the timer slots to your own needs (or completely
+ wipe them ;-)
