looked through the user manual but it only highlights where the adjustment slider is on the screen (its not a touchpad though), its pretty hot weather and im lost trying to figure it out for him, can turn it on/off but dont know how to adjust the temperature. is there anyone with first hand experience with the 304SR or similar cabs who can help a brother, help his grandad out? he's 90 and still farming. thanks for your time!

    unfortunately no, didnt have any knobs like that, only two which were digital spinners, one influenced the digital screen the other did something with the engines revs? thanks for the try

    Got a Serial Number.? Then someone can look up the appropriate manual based on that. Maybe the manual he has is not the correct one for his S/N.

    Selecting the "HVAC" Menu will navigate the user to the HVAC display screen. From the "HVAC" menu, the user will be able to adjust or perform the following: Air Conditioning On/Off Fan Speed Temperature Control Maximum A/C Defrost Automatic Temperature Control (If Equipped)

    (1) Jog dial (2) Heating and Air Conditioning button The heating and cooling menu can be directly accessed by pressing button (2) on the right side switch panel. Input selections can be made using jog dial (1). For more information on Air Conditioning and Heating Controls refer to Operation and Maintenance Manual , "Air Conditioning and Heating Control".
