PRE-DIVE SETUP
Fig. 4.4
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 PO
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 systems
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. The system will boot up and perform internal checks.
This will take about 30 seconds. Then the Hollis splash screen will ap-
pear followed by the training acknowledgement screen (Fig. 4.4).
!
DANGER: It important that you have read this manual and are prop-
erly 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.
PRE-DIVE CHECKS PURPOSE
These tests are designed to:
1. Check that all functions of the EXPLORER have a high likelihood of oper-
ating correctly.
2. Detect assembly errors.
3. Detect breathing loop errors.
