!Warning
For your own safety, follow the safety
advice given below.
The most important factor in diving
safely is a competent and well trained
diver, diving within his or her abilities.
This dive computer is intended for
experienced divers. That implies:
A diving education incorporating
decompression diving is mandatory.
Sufficient knowledge about the laws of
physics in diving is required.
Relying on a wrongly congured dive
computer might harm health.
Precautions

16
Do not use this dive computer if you are
not familiar with or don’t understand
the settings and displayed information
of OSTC3.
If necessary, you must be able to nish
your dive safely without the aid of a dive
computer.
Donot adjustdecompressionparameters
unless your are aware of their meanings.

17
Plan your dive.
Set up a dive plan independently from
OSTC3, and take it with you when diving.
Make sure that your OSTC3 is ready for
use and correctly configured.
Always conrm the following questions
before diving:
Stable Firmware?
Use only rmware provided by heinrichs
weikamp which is marked as “stable”. It
has been tested and allows for a reliable
performance of OSTC3
Configured Correctly?
Check the settings of your OSTC3. If
necessary, adjust the settings according
to your dive plan and equipment.
Before Every Dive

18
Battery status?
Check the battery status using the
battery indicator on the display. To
ensure reliable performance throughout
your dive, the battery level must be
sufficiently high. A new Saft LS14500
(Lithium primary cell) allows up to
60hours of diving, a quality Alkaline AA
battery (e.g. Duracell Ultra Power) about
30hours, a Lithium 1,5V Battery (e.g.
Energizer E2) about 40hours.
Device waterproof?
Ensure that both the USB connector
cap and the battery compartment are
properly closed and watertight. Check
the housing for cracks or damages which
might allow water to intrude.

19
Safely attached?
Make sure OSTC3 can be fastened safely
using either the bungee or a suitable
alternative.
Display messages?
Check the display of OSTC3 for warnings
or other signals. Do not dive if the OSTC3
displays a warning, e.g. the warning
symbol. Check the cause for the warning.

20
Take a backup system with you.
While diving, always carry a backup
system to measure duration and diving
depth independently from OSTC3
Take the OSTC3 with you on every repeat
dive – don’t lend it to anyone.
A correct calculation of tissue saturation
requires that OSTC3
• is congured correctly
• is used on every dive
• is only used to record data during your
own dives (and not shared with other
divers)
