1. Introduction
The MKVI can support decompression diving. To be able to perform decompression dives, you
need two things: 1) the appropriate training, and 2) a decompression-enabled battery module.
The decompression battery module is available in three versions: Blue, Yellow or White.
- The Yellow battery module allows decompression dives to a maximum depth of 40m with air
as a diluent.
- The Blue battery module allows decompression dives to 48m with normoxic trimix (minimum
16% oxygen) as diluent.
- The White battery module allows decompression dives to 60m with normoxic trimix (minimum
16% oxygen) as diluent.
The decompression diving battery modules give you the opportunity to do both recreational
no-decompression diving and technical diving without changing the battery or MKVI rmware.
The four different battery modules, referred to as the “Recreational 40m”, “Deco 40m”, “Deco
48m trimix” and “Deco 60m Trimix” batteries, each have different hardware keys. They are all
independent from each other and are not sensitive to rmware changes. Starting with rmware
v48 the MKVI has full support for decompression diving when one of the appropriate decom-
pression battery modules is inserted into the unit.
WARNING:
The battery is your personal decompression diving key, do
not lend it to anyone who is not properly trained in its use.
Only properly trained divers are allowed to use either the
decompression-enabled battery modules with a MKVI rebreather.

WARNING:
Diving to 60m affects the canister duration. The canister has
been tested for a duration of 120 minutes at 60m, water temp 4°C,
and a breathing rate of 40lpm producing 1.6 l CO

per minute
at STPD (Standard Temperature & Pressure, Dry in accordance
with EN14143).
