Page 4: Warning
WARNING Decompression meter firmfare calculates theoretical tissue saturation with inert gases based on a mathematical model. This model was made thanks to a variety of experimental data with the latest decompression theory developments. Nevetherless, using the dive computer, as well as decompression tables cannot guarantee complete protection against Decompression Decease (DD). -
Page 5: Av1 Dive Computer General Description
1. AV1 DIVE COMPUTER GENERAL DESCRIPTION AV1 dive computer (further – AV1) shows all important dive parameters and decompression information on the screen. -
Page 6: Main Parameters And Display Functions
Main screen will happen in 5 minutes. In Surface mode buttons are set to maximum sensitivity. You can set AV1 in such a way that AV1 could automatically decrease buttons’ sensitivity in Dive mode in order to avoid occasional buttons’... -
Page 7: Units Of Measurement
Operation time with fully charged battery is about 10 hours. If you don't use AV1 for a long time, charge it at least once in 2 (two) months. It will prolong battery life. With full battery discharge all the information (current settings, current tissue saturation) will be lost! Don’t take too much effort when screwing the cap! -

CNS level taking into account your surface interval. AV1 will automatically switch to Dive mode within 10 seconds of 2 meters' submerging. AV1 will also automatically switch from Dive mode to Surface mode, if the depth is less than 1(one) meter within 2 minutes. -
Page 9: Switch Sp
->Switch SP (only in CCR mode) manual switching between Low, High and Deco Setpoints. Choose the required Setpoint with button Next and confirm with button ОК. ->Dive setup -> Entry to the submenu of dive mode settings ->Edit mix Gas list editing. Here you can add gases into active gases' list which will be available in Select mix menu item. - Page 10 Accordingly, you can now set you diluent in CCR mode as active CCR gas, as well as all bailout gases as OC ones. In this case, decompression and TTS in CCR mode shall be calculated based on diluent, and in the case of switch to OC automatically calculated based on OC gases and will offer the gas from the list of OC gases.
- Page 11 CCR". Additional depth level is required, if before ascending decompression time some horizontal route is supposed, for example, in the overhead environment, or to the buoy. CAUTION!!! This level is taken into account if it is shallower than the current depth.

See in detail – Oxygen Cells' Control. 5. MAIN OPERATION MODES If your AV1 is in Sleep mode, nothing is displayed on the screen. Nevertheless, the computer keeps monitoring ambient pressure and calculates desaturation. For switching from Sleep mode to Surface Interval mode – press subsequently left, then right buttons. -
Page 22: Surface Interval Mode
5.1 Surface Interval mode By pressing MENU you move to AV1 Main menu. By pressing MIX you move to SubMenu for selecting current gas. When Surface Interval mode is activated, the following main settings will be displayed on the screen: ... -
Page 23: Dive Mode
Violation warnings of the last dive (if any happened). 5.2 Dive mode In Dive mode AV1 has two options of information indication on the screen: Basic and Alternative screens. Both screen options can be turned on both in OC and in CCR mode. - Page 24 FAST - ascending speed higher than 10m/min. System warning, stored in the logbook. Not bestmix – it is recommended to change the gas. There is gas in the list of active gases which better than the current one. Gases are compared by MOD. The gas / gas mix with maximum MOD not higher than current depth is considered to be the best mix.

You are making ALL your dives in Gauge mode at your own risk! IMPORTANT! Upon diving in Gauge mode, do NOT dive with AV1 as decompression meter earlier than 48 hours since the last dive in Gauge mode !!! Otherwise incorrect tissues' saturation probabilty is very high. As a consequence, you will be under high risk of decompression decease! 5.3.2 Average Depth calculation and Dive Segment Time... -
