FAQ
Q: What happens if I replace the battery after a
dive, before the desaturation time has run out?
A
:
The residual nitrogen memory will be cleared,
and the RGBM calculations for any previous
dives will be aborted. The diver who used the
computer in the previous dive must not dive for
at least 24 hours.
Q: What happens if I start a dive while Nemo
Wide is still in OFF mode?
A
:
If left in OFF mode when you begin the dive,
Nemo Wide will still activate DIVE mode within
20 seconds of descending past 1.5 m (5 ft).
Q: When I replace the battery, will my Log Book
dive data be lost?
A
:
No.
Q: What happens if there is an uncontrolled
ascent or omitted decompression stop during
an “AIR” or “EAN” dive?
A
:
Nemo Wide automatically switches to
“Stop” mode at the end of the dive. The only
Scuba mode that remains active in this case is
“Bottom time”.
Q: What indicates that “Bottom Time” mode
was chosen by the user, rather than forced as
a result of underwater behavior errors during
the preceding dive?
A
:
In the latter case, during the dive and in
surface mode, the pertinent error icons are
displayed along with the standard “Bottom
Time” indications.
Q: If I select “AIR” or “EAN” mode after
completing a dive in “Bottom Time” mode, how
will the new dive be managed?
A
:
Nemo Wide does not allow you to do
an “AIR” or “EAN” dive in the 24 hours
immediately following a “Bottom Time” dive.
Q: Why is the PLANNING mode disabled
sometimes?
A
:
This happens if you end a dive with an
omitted stop or an uncontrolled ascent. If this
happens, Nemo Wide switches to BOTTOM
TIME and prevents use of the Dive - AIR and
Dive - EAN for 24 hours.
Q: What is the purpose of “OFF” mode?
A
:
By placing Nemo Wide in “OFF” you
can display the specifications of your dive
computer.
Q: Where can I find the product serial number?
A
:
In OFF mode.
Q: If I already own the Iris interface, can I use it
with Nemo Wide?
A
:
No.
Q: Sometimes the temperature indication is
too high in time mode.
A
:
The thermometer was calibrated for use
underwater; out of the water Nemo Wide is
affected by your body temperature. Therefore
if you want a more accurate temperature
reading, we suggest that you take the Nemo
Wide off your wrist and leave it for a few
minutes on a surface that is not influenced by
other temperatures.
Q: Are the 3 minutes of the safety stop included
in the ASC time?
A
:
The 3 minutes of the safety stop are not
included in the ASC time.
Q: What is a DEEP STOP?
A
:
To minimize the likelihood of critical bubble
seed formation, in case of decompression dives
or dives close to the no-deco limit, Nemo Wide
prompts for a series of one-minute Deep Stops
at different depths depending on the dive profile.
This is one of the special characteristics of the
RGBM Mares-Wienke Algorithm. For more
information visit: www.rgbm.mares.com
Q: If I ascend above the depth for the DEEP
STOP can I go back down to do the stop?
A
:
If you surpass the stop by more than a meter
(3 ft), the stop is canceled.
Q: Why doesn’t the DEEP STOP icon appear
during the dive?
A
:
The DEEP STOP only appears for
decompression dives or dives close to the deco
limit.
Q: If I start my DEEP STOP and then go back
down what happens?
A
:
If you begin the DEEP STOP and then
descend, the countdown stops. It resumes
when you return to the DEEP STOP depth.
Q: Why doesn’t Nemo Wide turn off after a
dive?
A
:
If the no-fly period has not expired, after a
dive Nemo Wide switches to TIME mode and
shows information about the most recent dive.
If you want to turn off the Computer, use the
OFF command.
MAINTENANCE
After diving in seawater it is recommended
that you rinse Nemo Wide with fresh water to
remove any salt residues.
Do not use chemical products; just put the
Nemo Wide under running water.
NOTE
If signs of moisture are observed on the
inside of the mineral glass, take your Nemo
Wide to an authorized Mares service center
immediately. In any case, Mares declines
responsibility for any water seepage that
results from errors in replacing the battery.
WARNING
The mineral glass is not exempt from
scratches resulting from improper use.
REPLACING THE BATTERY
Replacing the battery is a delicate operation,
and requires close attention.
We suggest that you visit an authorized Mares
center. Mares declines all responsibility for any
damage caused by replacing the battery.
Unscrew the waterproof cover located on the
back of the Nemo Wide, turning it counter-
clockwise (Fig 34).
FIG. 34
REMOVE THE BATTERY
NOTE
Do not discard the old battery in the
environment.
Mares respects the environment, and
urges use of the appropriate separated
waste collection service.
Insert a new battery, Lithium CR 2450, making
sure the polarity is correct.
WARNING
Inspect the O-ring carefully, checking for
any signs of damage, tearing or warping.
If necessary, replace it with a new O-ring
(Mares spare part Code 44200723).
POSITION THE GASKET IN THE COVER
Set the cover on the Nemo Wide, making sure
that the icons are positioned correctly (Fig. 35).
