The SYMBIOS HANDSET can be used for sport as well as for technical diving. It is possible to use it with Air, NITROX or TRIMIX open circuit diving as well as closed circuit rebreather diving with constant pO2 setpoint.
Dive mode is automatically activated, as soon as the diver reaches a depth >1 m.
After surfacing, and after a 2min timeout, surface mode is activated.
During diving,
☞Press and release the top button to switch between different screens
The left lower field on the screen is the custom field. The default item shown in this field can be preset in menu/SYSTEM/CUSTOM FIELD.
☞Press and release the lower button to switch between different items in the user selectable custom field of the screen.
After 60s, the item in the custom field will switch automatically back to the preset field in menu/SYSTEM/CUSTOM FIELD
☞Press and hold the top button to enter the menu
☞Press and hold the lower button to perform the custom function (see menu/SYSTEM/CUSTOM FUNC)
In open circuit diving mode or closed circuit bailout mode, the default setting for this function is to confirm a suggested gas switch.
In bottom timer mode, the default setting for this function is to start/reset of the stop watch
The SYMBIOS HANDSET features different screens. Press and release the top button to switch between different screens
This example shows a screen during diving. The current depth is 22.8 m, dive time is 7 min, remaining tank pressure is 138 bar and the remaining no decompression limit is 13 min.
Press and release the top button to switch between different screens.
The second screen shows auxiliary data. This example shows a third screen while diving.
Additional screens, that show for instance wireless information or a detailed deco schedule can be enabled in the menu.
The risk of decompression sickness (DSC) or Oxygen toxicity for any dive profile, even if you follow dive tables, or a dive computer, cannot be totally eliminated. This risk also depends on the individual diver’s physiological condition, which can vary from day to day. The SYMBIOS HANDSET cannot account for these variations.
We strongly advise you to stay within the exposure limits provided by the instrument to minimize the risk of DCS. However, even if you stay within recreational limits and the no decompression limits given by this dive computer, DCS may appear.
Before diving you should consult a physician regarding your fitness to dive.
In recreational diving do not dive with a pO2 > 1.4 bar. Diving with a high pO2 may lead to O2 intoxication
Never dive with a pO2 > 1.6 bar. Diving with a pO2 >1.6 bar will lead to O2 intoxication.
Do not dive deeper than what your current diving qualification allows you to.
NITROX diving requires proper training. Do not dive with NITROX without a NITROX certification.
Besides the decompression stops, there are no additional mandatory safety stops or error messages displayed when the decompression ceiling and time, or the recommended ascent rate are violated.
Do not violate the ceiling depth during your decompression. In order to avoid doing so by accident, you should stay slightly below the ceiling depth. Staying deeper than the required ceiling depth will increase your total time to surface
Do not use breathing gases other than air, unless you are properly trained and NITROX or TRIMIX certified.
Do not use breathing gases other than air, in particular hypoxic TRIMIX breathing gases with a O2 fraction of less than 20 %, unless you have been properly trained in using those and unless you have a TRIMIX certification
