Specifications

complete all of your ascents with the TLBG inside the green zone. While you

cannot provide a guarantee against the occurrence of decompression

sickness, you may choose your own personal zone of caution based

upon your individual age, physique, excessive weight, training, experi-

ence, etc. to reduce the statistical risk.

The Ascent Rate Indicator (Fig. 28) shows how fast you are ascending. When

you exceed the maximum prescribed ascent rate of 60 feet per minute (18 meters

per minute), the segments will enter the red zone and you will be alerted by a

flashing bar graph. Rates as they correspond with the bar graph are: 0 seg-

ments = 0 to 20 fpm (0 to 6 mpm), 1 segment = 21 to 30 fpm (6.5 to 9 mpm), 2

segments = 31 to 40 fpm (9.5 to 12 mpm), 3 segments = 41 to 50 fpm (12.5 to 15

mpm), 4 segments = 51 to 60 fpm (15.5 to 18 mpm), and 5 flashing segments =

61+ fpm (18+ mpm).

Dive Log Mode

Dive Log Mode, identified by the Dive Log icon (Fig. 29a) located above the

Surface Display icon, can be accessed while on the surface using the button on

the front of the module. Information from your 12 latest dives is stored in the

log for view. After 12 dives are accumulated, each subsequent dive will over-

write the oldest dive that exists in the log, i.e. the Data100 will add the most

recent dive while deleting the oldest. Information is not lost when batteries are

removed from the unit.
