14. DIVING – DIVE START
BLACK BT is equipped with water sensor activated automatically once in contact
with water; therefore, it does not require to be turned on manually before entering
the water. It enters the diving mode at depth of 1.5m.
Water sensor was calibrated to detect both salt and fresh water. However, in
particular environments (e.g. mountain lakes) water conductivity is too low for the
sensor to detect it. In such situation, the device will activate through pressure
sensor at depth of 0.5m.
If the battery charge level totals less than 20%, BT will not enter the
diving mode and will display message ‘Do Not Dive’. Always check the
battery charge level before entering the water.
Even though BT activates automatically, before entering the water
always make sure that the device operates correctly.
BLACK BT activates depth and time measuring mode after entering
the diving mode. The max. depth for the device to activate
measuring is 1.5m.
