All reminders and alerts are subject to limitations. The system may send you a reminder or an alert when no issue occurs, or may fail to send a reminder
or alert when an issue occurs. Nevertheless, please fully respond in a timely manner to any reminder or alert, but do not rely too much on them, as the
best protection is your own judgment, skills, and experience as a diver.
Violating a recommended decompression stop won't result in the device locking or other penalties. The device provides clear alerts for violating the
scheduled decompression plan, so that you can make decisions based on your training (including performing self-rescue, contacting your diving
insurance provider, or contacting a recompression chamber).
Safety stops are optional. Ignoring them won't cause the device to lock or other penalties, and there will be no alerts. However, it's recommended that
you perform safety stops as scheduled, to reduce the risk of DCS.
Apnea training and testing are dangerous. Please make an appropriate training plan based on your own physical condition. Complete the training and
testing under the guidance of professional personnel. For safety reasons, do not train or test alone.
During scuba diving, ascending too fast will increase the risk of DCS. Therefore, please maintain a safe ascend rate at all times.
You should have received relevant training before using the compass feature for diving, so exercise caution when using it. Before diving, make sure that
the compass works properly, and be sure to calibrate it. Metal objects, permanent magnets, and motors may affect the accuracy of the compass.
When you've done using the device, clean or soak the device with clean water for a short while to prevent contaminants such as sea salt particles or
sediment from accumulating on the device, as this can cause button, pressure sensor, or speaker failure. If the speaker fails, you'll need to drain water
from the device after the preceding step, and air-dry the device for at least 24 hours, before checking whether the sound has returned to normal.
