Using the Monitor 3 Air Without the Transmitter. A&D 2 Plus

Section 1: Preparation

Once paired, the Monitor 3 Air will always display the tank pressure of the cylinder to which the transmitter is connected, whenever it is in range.

Note: The pairing procedure only needs to performed once, before the first use. After that, the only time you need to perform the pairing procedure is when you use a new transmitter, new computer, or have the battery changed.

Always check the cylinder pressure before every dive.

For best possible reception, it is best to fit the transmitter on the same side of the regulator first-stage where you will wear the wrist unit. For example, if you wear the computer on your left wrist, mount the transmitter on the left side of the regulator.

Checking the Battery Power

You can manually check the battery power of the Monitor 3

Air. While in Ready Mode or Surface Mode, touch contacts

A&D. The word "bat" will be displayed along with the battery power. Battery power is given as a percentage, with

99% being the highest percentage displayed. Its a good idea to check the battery power before you start a series of dives.

Using the Monitor 3 Air Without the

Transmitter

If, for any reason, you are unable to use the transmitter, you can still use the wrist unit as a dive computer. It will provide all the normal information found in the MODE,

DEPTH and TIME zones. However, the influence of breathing rate and work load will not be taken into account in the decompression calculations. The AIR ZONE will remain blank and you will need to monitor your cylinder pressure using a conventional gauge.
