Operation Manual

DECOMPRESSION DIVE MODE

The XR1 is designed to help you by providing a representation of

how close you are to entering decompression. Decompression

Dive Mode activates when theoretical No Decompression time/

depth limits are exceeded.

Upon entering Decompression Mode, you should begin a safe con-

trolled Ascent to a Depth slightly deeper than, or equal to, the Re-

quired Ceiling Stop Depth indicated (Fig. 28a) and Decompress for

the Stop Time indicated (Fig. 28b).

 The UP Arrow and Stop Bar will flash if you are more than 10

feet (3 meters) deeper than the Required Ceiling Depth.

 Once within 10 feet (3 meters) of, and below, the Required Ceil-

ing Depth, both Arrows and the Stop Bar appear solid.

Deco - Main Display

The amount of decompression Credit time that you receive is de-

pendent on Depth, with slightly less Credit given the deeper you

are below the Stop Depth required.

You should stay slightly deeper than the Required Stop Depth indi-

cated until the next shallower Stop Depth appears. Then, you can

slowly ascend to, but not shallower than that indicated ceiling Stop

Depth.
