Programming M ode
By using the Field Programmer the follo wing functions may be
programmed directly into the LIFE GUA RD™ with out the necessity
of a P.C.
•
Added Conservatism factor
•
Depth Alarm preset
•
O2 Calibration
NOTE: It is essential that the LIFEGUARD™ be calibrated before its
first use and prior to the beginning of each diving day. Additional
calibration checks may also be advisable on an extended dive day.
The P rogramming Mode is entered from normal Surface Mode. If
Pre-Di ve Predict scrolling is taking place, wait until the c ycle is
completed before proceeding.
Characters and digits in the upper left corner of the W U display
indicate the function being programmed. Digits in the lower center
of the display indicate the values being set for each programming
element. For purposes of Programming and Calibration modes,
disregard the figures on the lo wer left and lo wer right corners of the
display. These are CNS and OTU o xygen to xicit y values as
e xplained later in this manual.
All programming sequences use the same routine of pressing the
“
SELE CT ” button to bring up the desired p rogramming element and
the “ INCREMENT ” button to change the values within the selected
element. It is necessary to hold the button do wn for appro ximately 1
second to cause the selected value to change. You may also hold
the buttons down fo r continuous scrolling through each button’s
sequence of available values. Each change of the SELE CT or
INCRE MENT value will cause the Computer-Tr ansmitter Unit (CTU)
to issue a single beep and the letter (SELECT) o r numeral
(INCRE MENT) to change as they are stepped through. If a value
requires three digits to be programmed, a -3, -2, and -1 will be
displayed in the upper left hand corner in that order. The -3
identifies the most significant (farthest left) digit, of the value being
displayed. The -2 identifies the ne xt most significant (center) digit,
and the -1 identifies the least significant (farthest right) digit.
To begin the programming sequence:
1. Insure that the O2 sensing unit is properly attached to the CTU by means of
the waterproof cable and fittings.
