+/*
+ Implements 16 alarm slots on the sensor watch
+
+ Usage:
+ - In normal mode, the alarm button cycles through all 16 alarms.
+ - Long pressing the alarm button in normal mode toggles the corresponding alarm on or off.
+ - Pressing the light button enters setting mode and cycles through the settings of each alarm.
+ - In setting mode an alarm slot is selected by pressing the alarm button when the slot number
+ in the upper right corner is blinking.
+ - For each alarm slot, you can select the day. These are the day modes:
+ - ED = the alarm rings every day
+ - 1t = the alarm fires only one time and is erased afterwards
+ - MF = the alarm fires Mondays to Fridays
+ - WN = the alarm fires on weekends (Sa/Su)
+ - MO to SU = the alarm fires only on the given day of week
+ - You can fast cycle through hour or minute setting via long press of the alarm button.
+ - You can select the tone in which the alarm is played. (Three pitch levels available.)
+ - You can select how many "beep rounds" are played for each alarm. 1 to 9 rounds, plus extra
+ long ('L') and extra short ('o') alarms.
+ - The simple watch face indicates any alarm set by showing the bell indicator.
