Tusa IMPREX II IQ-400, Инструкция по эксплуатации

• the ceiling descends to 12 m [39 ft]. A permanent error warning Er appears.
In this mode the IQ-400 can only be used as a depth gauge and timer.
The permanent ERROR MODE is shown by a non-blinking Er in the center
display. Once in ERROR MODE, the
IQ-400 will continue to display current
depth and dive time. You should immediately ascend to a depth of 3 to 6 m [10
to 20 ft] and remain at this depth until air supply limitations require you to
surface. When the surface has been reached, no further diving or flying should
take place for a minimum of two days.
3.3.5 Decompression Dives
Rather than requiring you to make stops at fixed depths, the IQ-400 permits
you to decompress within a range of depths.
Background
When your NO DEC TIME becomes zero, your dive becomes a decompression
dive, i.e. you must perform one or several decompression stops on your way to
the surface. The NO DEC TIME on your display will be replaced by a flashing
notation CEILING/ ASC TIME (Fig. 3.13).

WARNING
DO NOT USE THIS INSTRUMENT TO
CONDUCT DECOMPRESSION DIVES!
TUSA does not recommend this instrument to be used to con-
duct decompression dives. However, if through carelessness or
emergency a diver is forced to exceed the no-decompression
limits on a dive, the
IQ-400 will provide decompression infor-
mation required for ascent. After this the IQ-400 will continue
to provide subsequent interval and repetitive dive information.

WARNING
YOU SHOULD ASCEND AND BEGIN
DECOMPRESSION IMMEDIATELY WHEN THE IQ-400
SHOWS YOU THAT DECOMPRESSION IS REQUIRED!
