Handset Operational Overview
The options available in the primary handset are grouped into two main “menus”. The first
grouping contains the functions most likely to be used during a dive, while the second grouping
under the options menu ”OPT” is used to gain access to additional functions including handset
configuration. For safety reasons several functions in the second grouping are unavailable while
in dive mode.
The secondary handset has a similar arrangement, where the first grouping scrolls through
the user set-points, and the second grouping under the options menu ”OPT” is the configuration
functions. For safety reasons several functions in the second grouping are unavailable while in
dive mode.
Common Functions:
Set-Point Operation
One of the main features of the HammerHead is the ability for the diver to select a new
set-point based on a user programmed set of five choices. The HammerHead comes pre-
programmed with set-points of 0.4, 0.7, 1.0, 1.2, and 1.4. Regardless of the current operating set-
point pressing the left button will cycle through the set-point choices in sequence. Once the
desired set-point is displayed it is selected by pressing the right button and confirming once
prompted with the left button.
SELECTING DILUENT/ OC GAS
On the primary, the first option available is the gas selection
prompt. Pressing the right button will select this function. Each press of
the left button scrolls to the next programmed gas mix until all 10 are
displayed, eventually returning to first mix. Once the desired mix is
displayed, pressing the right button will select it. The diver will then be
prompted to confirm or cancel the mix change. Pressing the left button confirms the selection,
while the right button or no action for 10 seconds cancels the switch.
