Maintenance
The depth accuracy of your M2 should be
verified every two years and can be done
by an authorized SCUBAPRO dealer. Aside
from that, the M2 is virtually maintenance
free. All you need to do is rinse it carefully
with fresh water after each dive and change
the battery when needed. To avoid possible
problems with your M2, the following
recommendations will help ensure years of
trouble-free service:
- Avoid dropping or jarring your M2.
- Do not expose your M2 to intense, direct
sunlight.
- Do not store your M2 in a sealed
container; always ensure free ventilation.
If there are problems with the water contact,
use soapy water to clean your M2 and dry
it thoroughly. Do not use silicone grease on
the water contacts!
- Do not clean your M2 with liquids
containing solvents.
- Check the battery capacity before each
dive.
- If the battery warning appears, replace
the battery.
- If any error message appears on the
display, take your M2 back to an
authorized SCUBAPRO dealer.
The tank pressure gauge and the parts of this
product used to measure tank pressure should
be serviced by an authorized SCUBAPRO
dealer every second year or after 200 dives
(whichever comes first).
7.3
Replacing the battery in
M2 or transmitter
The main battery change must be made
with particular care in order to prevent
water from seeping in. The warranty does
not cover damages due to the improper
placement of the battery.
