2.The SYMBIOS HUD will be recognized as mass storage device.
3.Download the latest firmware
4.Unpack the firmware zip file RNO_HUD_FW_Vx_xx_xx.zip
5.Copy the files from the zip file to the mass storage device.
6.Safely remove the mass storage device
7.Disconnect the SYMBIOS HUD from your PC
The SYMBIOS HUD is then automatically updated with the new firmware.
The version of the firmware on your SYMBIOS HUD is shown in menu/SYSTEM/FIRMWARE VERSION
Make sure that the SYMBIOS HUD is fully charged, before performing a firmware update.
All decompression information and settings may be lost after a firmware update.
Avoid a firmare update between repetitive diving. Performing a firmware update between dives will cause the SYMBIOS HUD to loose decompression data and the remaining compartment inert gas loadings from the previous dives, thus the no decompression times and decompression calculations for the next dives may be incorrect.
