SECONDARY Handset Options and Programming

The secondary handset has many of the same options as the primary handset. The

notable differences are the lack of functions supporting the deco computer and set-point

control options. The secondary has FOUR additional options, “Stack Time Opt” ,

“Decompress Mode“, “Display Options” and “Set DIVA Mode”.

STACK TIME OPT

The stack timer is convenience reminder, and should not be counted

on as a life support feature. How useful this option is to the diver is

dependent on how faithfully the diver remembers to reset the counter after

each scrubber change. The stack timer cannot be disabled, but the user has the freedom to set their

own limits and can reset the timer at any time. Selecting “Stack Time Opt” under the “OPT” menu

allows the user to scroll through several options relating to the stack timer function.

VIEW STACK TIME

The “View Stack Time” option can be used at any time to view the

timer limits and how much UNDERWATER time has been put on the

scrubber. This is a VERY important concept to remember, time spent on

the loop but not at depth is NOT counted towards stack time. Scrubber

durations in excess of the limits (stack overrun) will be displayed as a

negative time remaining.

SET STACK TIME

The “Set Stack Time” option allows the user to set the scrubber

duration timer in 60 minute intervals ranging from 60 to 600 minutes.

Upon entering this function the stack time is set to 60 minutes, the diver

now must set the timer limit by using the left button to increment by 60

minutes at a time, with the right button programming the displayed time.

WARNING Even if the right button is not pressed, once the programming screen times out, the

scrubber limit will be set to whatever is currently displayed as the new limit. Time previously

counted as “on the stack” is also reset. This function can be seen as setting the scrubber stack time

limit and resetting the counter to the new limit.
