This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
Nothing wrong with the manual or the delivery - came to me the same day I ordered it. But afterwards I realized that I ordered the wrong manual. Probably better with the Quick start - version. So maybe it would be better if we could see a list with inhold for each manual before ordering?
Bought T4850 High End Tuner a few years ago, but i didn't know where all the buttons were used for. So i purchased the owners manual. Perfect! Just what i needed.

A Note on Power Handling
As a result of their high ef�ciency, all JBL loudspeakers will produce reasonable volume levels in the automotive environment using very little ampli�er power. However, the use of a small ampli�er to attain very high volume levels could lead to overdriving the ampli�er. This will generate high distortion levels which can easily damage loudspeakers, even if the rated power of the ampli�er is below the rated maximum power handling of the loudspeaker!
As a general rule, do not turn up the volume control past the point where you hear distortion in the form of either signal distortion from an overdriven ampli�er or mechanical noise from an overstressed speaker. For the best performance and system reliability, you should select an ampli�er with an output rating greater than the maximum power likely to be used to generate the desired volume levels.
If you want your system �Loud + Clear,� we suggest that you step up to a JBL power ampli�er which has an RMS power rating equal to, but not exceeding the Maximum Recommended Ampli�er Power listed in the speci�cations of your speci�c JBL speaker. This margin of reserve power will ensure that the ampli�er will not attempt to deliver more power than its design allows. Your dealer will be happy to point out which high power JBL ampli�ers are optimum for your application and listening habits. Following these guidelines will provide virtually distortion-free sound reproduction and long loudspeaker life.
WARNING: Playing loud music over 120dB can permanently damage your hearing. The maximum volume levels achievable with JBL components and high power ampli�cation may exceed safe levels for extended listening. When listening at high volume levels, always use hearing protection or turn it down!
