Having assembled and tested the unit upon receipt, it is still critical that all
pre-dive tests are conducted prior to diving.
The EXPLORER is equipped with a set of pre-dive checks that are built into
the electronics prompting the diver to test certain aspects of the unit prior
to diving. Additionally, there are several manual tasks that should be com-
pleted prior to this final system check. These checks automatically start
once you turn the unit on. A complete flow chart of all the screen layouts
can be found on the enclosed CD and in the rear of this manual.
TURN ON SYSTEMS
The EXPLORER can be fully activated in three separate ways:
1. By button push
2. By breathing (breath detection as a low PPO
2
of 0.17 is reached)
3. At depth (>1.15 bar absolute pressure or about 5 ft/1.5 m)
DANGER: The batteries must be charged for the automatic sys-
tems to work. If the batteries are not charged the unit will not
turn on and not support life.
To turn on EXPLORER simply press both buttons on the handset and
hold for 3 seconds. After which, the Hollis splash screen and then the
training acknowledgement screen (Fig. 4.2) will appear.
DANGER: It important that you have read this manual and are
properly trained in order to complete the Pre-dive sequence
and dive EXPLORER safely. If you have not undertaken these
steps yet, do not proceed any farther.
By selecting CONFIRM the Pre-dive sequence starts and you will be
prompted through the sequence.
At the end of a successful Pre-dive sequence you will see the check
resources screen (Fig. 4.3).
At this point you should cycle through the screens by pressing the
left or right button to check that all resourcesare adequate to com-
plete the dive. After a few seconds the display will time-out to the Dive
screen (Fig. 4.4).
