Superprint 4425: Hold down the [Ctrl] key and press the  key.
You will see PRINT (UP/LOW) CASE on the display.
- Press the [Return] key until you see TURBO CODE (ON) on the display.

Follow the steps above if you want to turn Turbo Code on again.
TIP: Residential or Business
Has something changed recently in your telephone environment? If your Telephone Service Provider (ie., AT&T, Spectrum, ComCast, etc.) switches from traditional analog service to digital/VoIP service, you may experience garbling during your calls. Your telephone service provider is able to adjust settings on their end to correct this. Contact your Telephone Service Provider and ask them to set the phone line to use G.711 voice codec (uncompressed) to support modem, FAX and TTY transmission.
