ICOM IC 756 PRO 3 Initial Audio Settings
I have created these instructions to assist when an operator is unsure of how to initially adjust the IC 756PRO3 audio. These instructions will detail setting the SSB Bass and Treble audio settings as well as setting the Transmit Band Width in Wide, Mid and Narrow. I have also included instructions on setting the Compression Level. These instructions are how I currently have my transceiver set.
Entering the SET MODE Menu:
a) Press and hold the Exit/Set Button until the menu below is displayed
b)Press the Level Key (F-1) - You are now in the Transmit Audio LEVEL SET menu
Setting Bass and Treble Response
Using the Up and Down Triangle Icons, Select SSB TX Tone (Bass) - Rotate Main Tuning Dial +3
Using the Up and Down Triangle Icons, Select SSB TX Tone (Treble) - Rotate Main Tuning Dial +2
Setting SSB Transmit BandWidth - Wide
Using the Up and Down Triangle Icons, Select SSB TBW (WIDE) L - Rotate Main Tuning Dial to 100

You may adjust the other BandWidth settings(Mid and Narrow) to your own settings
Press the EXIT/SET button to exit this menu
