The last of the above conditions allows the user to manually force the device to work in
underwater mode when the depth sensor is found to be working improperly. This
prevents the device from going into Surface mode and automatically turning off after 15
minutes of inactivity.
9.3 Device operating time
The device is powered by standard AA alkaline battery (it is recommended to use a
battery with a minimum capacity of 2000mAh). In the sleep state, the device consumes
the electricity in the range of single milliamps - the discharge time of the battery is in this
state is up to 400h. Power consumption in the sleep mode (when the device is off with
the battery installed) is associated with the need for pressure measurement to detect
immersion. Measurement is performed every 9 seconds.
When in use, the discharge time of the battery depends on several factors:
•
screen brightness
•
ambient temperature (lower temperature - lower battery performance and shorter
operating time)
•
battery age (over time, cell electrodes get partially degraded, which reduces
battery performance and battery life, use of "fresh" battery is recommended)
Device operating time:
•
“LOW” screen brightness: up to 20 hours
•
“MEDIUM” screen brightness: up to 15 hours
•
“HIGH” brightness: up to 9 hours
In the event of total battery discharge (battery voltage is less than 0.9V), the power
system stops working. In this situation, the device is immediately shut down. If the
situation occurs during a dive, except for retaining the basic functionality of the device,
the decompression data is deleted because of the inability to continue the calculation
and to protect against false values.
If you do not use the computer for a long time, it is recommended to remove the battery
from the device.
The real time clock is still running, powered from the backup source, for up to 24 hours.
