Using TONE oregon 700

Hi All,

I've developped an App for my Oregon 700 that display a message in a simple data field to remind to Drink every 10mn and eat/drink every 50mn and play a tone at each message. That's work well, but know I would like to play different tone for Drink and Eat/Drink. I've specified two different tone value (TONE_ALERT_HI and TONE_ALERT_LO) but when running the app on my Oregon 700, the tone is always the same whatever the message is. I've noticed that the tone played was the one selected in the Oregon system menu for "Tone message"

Any Idea ?
