Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.
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.
The manual was properly scanned and perfectly readable. The only small problem is that I couldn't use my dear Ctrl + F to find a word I needed.

INSTALLING SPIKED FEET
Entra Two and Entra Three
Refer to Figure 4 as you perform the following steps: 1. The Entra Two and Entra Three come with the round end of their feet exposed for use on hard-surface floors.To expose the spiked end of the feet, lay each speaker on its side and use the enclosed wrench to unscrew and remove the four feet. Screw the round end of each foot into its hole and hand-tighten a nut onto each foot. Leave a minimum of 5/8" of exposed spike. (On thicker carpets, you can increase the length of exposed spike up to 1-1/8. ) " 2. Carefully stand each speaker upright to sit on its feet. 3. If needed, adjust the feet so each speaker is level and then tighten each nut with the enclosed wrench.
