The LED's don't seem to do what the the alarm bits specify, altho the alarm sounds ok.

Code:
; Alarm: Is 5 ":" seperated fields:
;        min:   Minimum value, below which the alarm will sound.
;        max:   Maximum value, above which the alarm will sound.
;        style: Is one of:
;                0 = No sound, No LEDs
;                1 = Low pitch
;                2 = Medium Pitch
;                3 = High Pitch
;                4 = Very high Pitch
;               16 = Illuminate LED 1
;               32 = Illuminate LED 2
;               48 = Illuminate LED 3
;               64 = Illuminate LED 4
;              128 = Illuminate LED 5
;               Add Pitch and LED values together to enable audio and visual alarms.
;               For example, for Medium Pitch and LED 4, use 2+64 = 66
;        time:  Time (in 10ms increments) for which alarm will be sounded.
;        hold:  Time (in seconds) for which the displayed value will be frozen (not implemented yet).
