your certification level. Diving with an incorrect
assessment of your ability and physical condition can
result in injury or even death.
●MISSION2 is designed for recreational diving. Do not use
MISSION2 for commercial diving Applications.
●Divers should never ascend faster than 10m/min
(33ft/min). Ascending faster than this will negatively
impact your decompression physiology.
●Please follow the decompression stops advised by
MISSION2. Violation will increase the risk of
decompression sickness, which may lead to serious
injury or death.
●The MISSION2 is a precision instrument. Take care to
protect your computer from damaging shocks or
chemical exposure. Store your MISSION2 out of direct
sunlight and avoid exposure to excessive heat or leaving
it in a vehicle exposed to the sun.
●Do not wear your MISSION2 in hot springs, hot tubs or
saunas.

2.1 Heart rate measurement
※ The wrist optical heart rate sensor measures the heart rate
with the LED optical sensor on the device. The blood flow per
unit area in the blood vessel will change with the heart pulse,
and the light sensor will obtain the change of the user's heart
rate based on the change of the blood.
Enable Heart Rate: Settings > Widget > Heart Rate: On
Checking the heart rate: after enabling the widget, press
button C on the main screen to scroll to the information page.
※ To ensure accuracy, MISSION2 should be worn correctly and
should not be worn on the wrist joints.
※ When exercising or in daily use, MISSION2 should be snugly
worn on the skin of the wrist to avoid uneven reflection of the
light beam. Objects such as long-sleeved clothing or winter
clothing shall also be avoided.
※ The heart rate function is disabled by default during dive or
swimming.
※ The heart rate may vary greatly due to light wavelength
absorption underwater, which in turn affects the optical
detection.
Causes of abnormal heart rate:
●Avoid Applying sunscreen or skin lotion, which will result
in uneven reflection of light, and keep the wearing area
clean.
●Arm hair, tattoos or skin tone, arm movement,
subcutaneous blood flow, etc. may all affect heart rate
measurements.
●In the cold weather or people with cold hands and feet
have poor blood circulation, which affects blood flow
and results in heart rate abnormally. Keeping hands and
feet warm will improve the accuracy of heart rate.
●Please avoid scratches or damage to the heart rate
sensor on the back of MISSION2
●The heart rate sensor should be kept clean.
Note:
※ MISSION2 is not a medical device, so the heart rate data
should not be used as a reference for medical use or
medical diagnosis.

About Tides
The phenomenon of rising sea level is called flood; the falling
sea level is called ebb. When changing from high tide to low
tide, when the water level reaches the relative highest, it is
called high water; when changing from low tide to high tide,
when the water level reaches the relative minimum, it is called
low water.
-There are three types of tides, namely semidiurnal tides with
two high and low tides a day, diurnal tides with only one high
and low tide a day, and mixed tides in between.
