Features of the Monitor 3 Air

The Monitor 3 Air is made up of two compact units: the

computer/display unit which is usually worn on the wrist,

and the high pressure (HP) transmitter which is screwed

into the regulator first-stage HP port.

THE COMPUTER SCREEN

The Monitor 3 Air has a large liquid crystal display (LCD)

and features large numbers and graphics. The screen is

luminous for easy reading during low light dives, including

night dives and cave dives.

The screen is organized into four zones (see figure on

opposite page): The MODE zone, DEPTH zone, TIME zone

and AIR zone. The Mode Zone has five icons which indicate

altitude, low battery, Pre-dive Planning Mode, Memory

Mode, and Surface Mode.

Next to the Mode Zone is the Depth Zone. This grouping of

numbers includes the current depth, maximum depth

decompression stop depth, and ascent rate information.

Beside the Depth Zone is the Time Zone. The Time Zone

shows total dive time, total ascent time, no stop time, and,

while in decompression, decompression stop time.

To the far right of the screen is the Air Zone. The Air Zone

shows current cylinder pressure, a graphical representation

of air time remaining and a digital readout of remaining air

time. In addition, their are two warning icons: one for

interrupted transmission and the other for high breathing

rate.

THE ELECTRICAL CONTACTS

All surface operations and mode changes are made by the

use of four electrical contacts placed around the Monitor 3

Air's screen. These contacts are identified as A, B, C and D

(see figure on opposite page). As a rule, contact A is always

touched in conjunction with one of the other three con-

tacts. After entering different modes, such as Memory

Mode or Pre-Dive Planning Mode, contact B always

decreases a value, and contact C always increases a value

(always in combination with A). To make contact, simply

moisten your fingertips and touch the appropriate pair of

contacts at the same time. Release the contact as soon as

the operation has been activated, usually no more than one

second.
