Display at the Ceiling Zone
When you reach the ceiling zone, the display will

show you two arrows pointing at each other (the

hourglass icon, Fig 4.20). Do not ascend above

this depth zone.
During decompression, ASC TIME will count

down toward zero. When the ceiling moves up-

wards, you can ascent to the new ceiling. You

may surface only when the ascent time reaches

zero and the CEILING/ASC TIME is replaced

by NO DEC TIME.
Display above the Ceiling
If you ascend above the ceiling, a downward

pointing arrow will appear and a continuous

beeping starts (Fig. 4.21). In addition, an error

warning Er reminds you that you have only three

minutes to correct the situation. You must im-

mediately descend to or below the ceiling.
If you continue to violate the decompression, the

Spyder goes into a permanent Error Mode. In this

Fig. 4. 20 Decompression dive, at

the ceiling zone. The two arrows

point at each other (hour

glass). You are at the ceiling

zone at 3.5 m [11 ft] and your

minimum ascent time is 4

minutes.

Fig. 4.21 Decompression dive, above ceiling. Note the

downward pointing arrow and the Er warning. You will

also hear an audible alarm. You should immediately

(within 3 minutes) descend to or below the ceiling.
