If during a dive the battery indicator starts flashing red, this is a sign that the battery is discharged and the dive computer may switch off soon or perform a reset. After a reset, dive data, depth, divetime and decompression obligations are incorrect.
Do not dive when the SYMBIOS HANDSET battery indicator is red. The dive computer might run out of battery. In such a case, the SYMBIOS HANDSET may give incorrect depth readings, incorrect decompression data or may shut off completely. In case of a red battery indicator, recharge the SYMBIOS HANDSET before the next dive.
Never fully discharge the SYMBIOS HANDSET , as this might lead to damage of the li ion rechargeable battery.
It the battery was completely discharged, the dive computer may reset and loose all decompression information. If reset occurred between repetitive dives, be aware that the SYMBIOS HANDSET looses decompression data and compartment inert gas pressure data from previous dives, thus decompression readings and no decompression calculations for following dives may be incorrect.
After a dive, before connecting the cable, rinse the SYMBIOS HANDSET in fresh water. Make sure that the USB connector is clear and dry before connecting the USB cable.
Do not disassemble or remodel any cable or connectors. Use only the original USB cable, supplied with the SYMBIOS HANDSET. Check compatibility before use.
Use only a clean and dry USB cable. Clean and dry the connector surfaces of the cable.
If the SYMBIOS HANDSET is completely discharged, let it charge for at least 3 h, before using it.
