Thank you for choosing a heinrichs wei-
kamp dive computer!
The OSTC sport is specially adapted to
sportdiving, it oers a simplied han-
dling and very big letters on the display
in dive mode. Thereby the OSTC sport
benets from the permanent further
development of the Tech-dive-computer
from heinrichs weikamp, because all
models are based on the same platform.
With rmware updates you can always
get your dive computer up to date.
We hope you enjoy diving with your new
OTSTC sport dive computer!
You can use the OSTC sport intuitively.
But to become familiar with its functions
and to use it in the best way, we recom-
mend you to read this manual carefully.

Requirements
The most important factor for safe diving
is a competent and well trained diver.
This dive computer is intended for ex-
perienced divers. That implies:
• A diving education including de-
compression diving is mandatory.
• Sucient knowledge about the laws of
physics in diving is required.
• It may harm your health if you rely on a
wrong congured dive computer.
• Do not use this dive computer, if you
don’t know or understand the settings
and displayed information of OSTC
sport.
• If necessary, you must be able to
nish your dive safely without a dive
computer.
• Don’t adjust decompression para-
meters if you are not aware of their
meanings.
Safety advices

Before every dive
Plan your dive.
Set up a dive plan independently from
OSTC sport and take it with you when
diving.
Make sure that your OSTC sport is ready
for use and correctly configured.
Always conrm the following questions
before diving:
Stable firmware?
Use only stable rmware provided
by heinrichs weikamp. It has been
tested and allows a proper and reliable
performance of OSTC sport.
Configured correctly?
Check the settings of your OSTC sport. If
necessary, adjust the settings according
to your dive plan and equipment.

14
Battery full?
Check the battery status using the
battery indicator on the display. To ensure
reliable performance throughout your
dive, the battery must be suciently
high. A new lithium primary cell (SAFT
LS14500) allows up to 50 hours of
diving, a quality alkaline AA battery (e.g.
Duracell Ultra Power) about 20 hours. a
lithium 1,5V AA battery (e.g. Energizer
E2) about 30 hours.
Device waterproof?
Ensure that the battery compartment is
properly closed and watertight. Check
the housing for cracks or damages which
might allow water to intrude.

15
Safely attached?
Make sure that your OSTC sport can be
fastened safely using either the bungees
or a suitable alternative.
Display messages?
Check the signals of OSTC sport. Do not
dive if your dive computer displays a
warning. Check the cause of the warning.

16
While diving
Take a backup system with you
While diving, always carry a backup
system to measure duration and depth
of your dive independently from OSTC
sport.
Take the OTSC sport with you on every
repeat dive – don’t lend it to anyone.
A correct calculation of tissue saturation
requires that your OSTC sport is:
• congured correctly
• used on every dive
• only used during your own dives (and
not shared with other divers).

17
Take a sufficiently long surface break
before diving again.
The OSTC sport doesn’t indicate how
long to wait before the next dive. Please
follow the guidelines you were taught
during your dive training.
Caution
Saturation data is lost when updating
the OSTC sport rmware or in the unlikely
event of a failure. In these cases, do not
dive any further until tissue saturation
has returned to normal level.

18
Safe use of the OSTC sport
Do not modify the hardware.
Modications to the hardware of OSTC
sport can damage its proper function
and can have bad inuence on the
watertightness of its housing.
Only the cap of the battery compartment
and the bungee backplate can be
removed. There is no other way to open
the housing without damaging the
device.
Only open the battery compartment
when the battery has to be replaced.
Keep your OSTC sport out of children´s
reach. Small parts such as the battery
cap may represent a choking hazard.

19
Environmental conditions
Store the OSTC sport in a cool, dry place.
Permissible temperature range for use
and storage: between -5 °C and 40 °C.
Make sure that the used battery is
suitable for the ambient temperature to
be expected in your dives. For cold water
diving (under 10°C) we recommand the
use of a Lithium battery.
Hint
Decompression calculations and depth
display are always based on the actual
surface pressure. So if you are diving
in mountain lakes, no further settings
are needed. OSTC sport automatically
adapts to the actual surface pressure.
Maximum water depth for operation:
70 meter.

20
Caution
• Surpassing the maximum water depth
may cause malfunction or permanent
damage of the device.
