Page 6: Welcome To The World Of Freedom
Congratulations on your purchase of a Divesoft Freedom – computer for technical diving. The FREEDOM is made with high precision in every detail from high-quality materials for long life in the harsh conditions of military, deep and cave diving. The solid aluminum shell protects high-tech electronics with the most sophisticated decompression software. - Page 7 Always use realistic SAC rates and conservative turn pressures during dive planning. Always take heed of visual and vibrating alarms of the device! You need to take into account the danger of nitrogen narcosis. The FREEDOM does not issue any warnings in connection with this danger.

Before the dive It is a good idea optimize your FREEDOM for your specific dive goals and needs. You can choose your decompression strategy in many ways, prepare gases for your dive and set alarms, among many more parameters. Salinity Main menu >... - Page 22 the surface. If the GF = 0.3, tissue compartments are saturated at 30% of M-value. Two GFs can be set: gradient factor low and gradient factor high. Gradient factor low determines the extent of oversaturation at depth. This value is relevant to the first decompression stop depth. GF high is the value of determined oversaturation at the end of ascent.

Diving with Freedom Open circuit – dive mode The dive mode is the heart of the FREEDOM system. The dive mode serves for online calculation of decompression using conventional open-circuit scuba equipment. It is possible to use a wide range of breathing mixtures, from Air and NITROX to HELIOX and TRIMIX. You can use up to nine variable mixes as travel, bottom and decompression mixes. -

Ascent time – length of time needed to reach the surface. It includes ascent speed, deep stops (if selected) and decompression stops. Ascent time is displayed instead of of No deco at the moment when decompression stops become necessary. Deep Stop – additional stops in the deeper part of the dive. Deep stops can prevent could the formation of microbubbles. -

Deep stop reached Safety stop. Stay between 6 and 3 meters for 3minutes. No-decompression dives Before the dive, activate your FREEDOM, go to Main menu and select Open circuit or make sure that you have set Open circuit as your Default mode for correct automatic activation. -
Page 34: Screensaver
During the dive it is possible to switch between screens with KEY 1. Open circuit menu remains available during the whole dive. During the ascent, maintain the ascent rate. In the case of exceeding the ascent rate, two red arrows are displayed in the right-side column and the alarm vibrates if it is set. -
Page 35: End Dive
The safety stop is interrupted if the diver falls below a depth of six meters. After returning above this depth, the safety-stop countdown starts again from the beginning. When the diver completes a safety stop and then falls below 10 meters again, then it is necessary to make a safety stop from the beginning. -
Page 36: Decompression Stops

Page 37: Diving With The Ceiling Method
If there is a difference greater than 18 m between the maximum depth and the first regular decompression stop, the FREEDOM shows the depth of the deep stop in the lower right box (if deep stops are set). When the diver reaches the deep stop depth, the countdown starts in the lower right box instead of the deep-stop depth. -
Page 38: Gas Switching
Make absolutely sure that you that you are using the regulator from the desired bottle! When you start breathing from a new bottle, switch to the currently used gas in your computer. There are two ways to switch gases in the FREEDOM. The first possibility is to access the Open circuit menu with BOTH KEYS. -

(BOTH KEYS) and select the “Show plan” item. The Freedom will display the list of decompression stops and the length thereof. Use of all set mixtures with gas switch at the optimum depth is anticipated in the calculation of the ascent time. -
Page 41: Fixed Ccr Mode
Fixed CCR mode The Fixed CCR mode is intended for apparatuses with a fully closed circuit (eCCR, mCCR) that do not have their own decompression computer but do have their own ppO2 monitor. In this mode, decompression is calculated on the basis of strictly set partial pressure, which corresponds to the selected setpoint on the rebreather. -

If you want to use Gauge mode after a scuba dive, make sure that you can use dive tables or decompression planning software for your next exposure. Divesoft is not responsible for any decompression problems caused by poor planning and using Gauge mode. -
Page 47: Plan
In the “Surface interval” item, use tilting or tapping to set the time interval between the current time and the time of starting the planned dive. The Freedom takes into account the diver’s tissue saturation with inert gases from previous dives. -
Page 48: Log Book
Only eight lines can be displayed on the Freedom computer’s screen. In the event that a planned dive requires more decompression stops, these are displayed on the following page. -

Air transport When transporting the Freedom computer by plane, the changes in pressure can cause activation of the device to occur. This can be due to an overly sensitive pressure sensor, which gauges pressure for the purpose of determining depth.
