Q: Why is the PLANNING mode sometimes
disabled after a dive?
A: This happens if you end a dive with an omitted
stop or an uncontrolled ascent. If this happens,
Puck switches to BOTTOM TIME and prevents use
of the Dive - AIR and Dive - EAN for 24 hours.
Q: What is SYSTEM mode for?
A: Putting PUCK into SYSTEM mode allows you
to view specific information about your dive
computer.
Q: Where can I find the product serial number?
A: In SYSTEM mode.
Q: If I already own the Iris interface, can I use it
with PUCK?
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 PUCK is affected
by your body temperature. Therefore if you
want a more accurate temperature reading, we
suggest that you take the PUCK 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 Ascent time?
A: The 3 minutes of the safety stop are not
included in the Ascent time.
Q: What is a DEEP STOP?
A: To reduce the chances of micro-bubbles forming
and growing, during decompression-stop dives or
dives very close to the no-decompression limits,
Puck will prompt for a series of deep stops of a
minute each at variable depths, as a function of 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 DEEP 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 PUCK turn off after a dive?
A: If the no-fly period has not expired, after a
dive PUCK switches to TIME mode and shows
information about the most recent dive.
MAINTENANCE
After diving in seawater it is recommended that
you rinse PUCK with fresh water to remove any
salt residues.
Do not use chemical products. Simply hold PUCK
under running water.
NOTE
If you notice signs of moisture on the
inside of the plastic lens, take your PUCK
to an authorized MARES service center
immediately. In any case, Mares declines
responsibility for any water seepage
resulting from an incorrect battery
replacement procedure.
WARNING
The plastic lens is not immune to scratches
caused by improper use.
WARNING
The plastic lens is protected by a plastic
lens cover that is easily replaceable (Mares
spare part Code 44200617).
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.
NOTE
Do not discard the old battery in the
environment. Mares adopts a policy of
respect for the environment, and urges
use of the appropriate separated waste
collection service.
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 Cod. 44200654).
Unscrew the waterproof cover on the back of
PUCK, rotating counter-clockwise.
Lift the cover, prying in the two grooves.
Remove the battery, paying close attention to the
proper polarity.
Insert a new battery, Lithium CR 2450, making
sure the polarity is correct.
