Initial Activation

i200C Dive Computers are placed in a Deep Sleep mode prior to being shipped from the factory. The intent is to extend storage life of the Battery for up to 7 years, before the unit is initially placed into service.

In this mode, Date and Time are updated as they normally would be. However, they are not displayed.

Upon waking the i200C up, the correct Date and USA Pacifc Time will be displayed. Here is where the use of the instructional manual comes into play. You will need to change the date and time to the correct one for the region that you are in.

Once you have brought the Aqualung i200C out of deep sleep, it is ready to operate with full functions.

To wake the i200C up from Deep Sleep mode, simultaneously depress the (Select) and (Down) buttons for 3 seconds until the display comes on displaying the Watch Main Time screen, then release them.

The Aqua Lung i200C comes packed with some great features. You will remember that we mentioned that the i200C does not come with a data cable, why?

The reason the i200C does not come with a data cable is that it is fully bluetooth activated!

To access all the bluetooth features, you will need to download the DiverLog+ app from the IOS or Android store.

DiveStyle Synopsis

The Aqualung i200C is an amazing watch sized dive computer that can be worn all day long. It is good looking enough to be an everyday functional watch and looks fantastic on the wrist. You can choose from 6 colours: Blue, Aqua, Hot Lime, Bright Pink, Grey and Dark Grey, making sure that there is a colour to suit you.

But looks aren’t everything!

The Aqua Ling i200C may be good looking, but as you can see, it is packed full to the brim with useable and useful features. For the traveling diver it even comes with a battery compartment key for user replaceable battery changes (please see our note on battery changes).

The other thing that grabbed our attention was the price. At just £299.00 we think it is superb value for money. In comparison to say the Suunto D4i, which has similar features (but no bluetooth capability) it is £96.00 cheaper that the recommended retail price!
