Is this what you need?
The "Text-Telemetry" you can open via the menu "Telemetry". With the "Text-Telemetry" you are able to display more telemetry values.

    In the opening screen of the transmitter press ESC for around ~2 seconds to switch into the telemetry.

    With UP/DOWN select Setting & Data View and open it with SET.
    Now either way click 1x arrow "UP" or 6x arrow "RIGHT".
    The Text-Telemetry will open.

The info is on the same page from you link (without the . in the link)

Gentlemen,
Thanks for your responses. I am able to access the text-telemetry using the procedures that you listed. The V4 is suppose to have a more graphical display of key info and allows the voice info to be heard at the same time. The webpage that I cited shows a photo of the new display.

Could you tell me how you brought up the mikrokopter-menu on your MX-20?

I am trying to access the mikrokopter-menu that is shown under Telemetry Display on http://www.mikrokopter.de/ucwiki/en/HoTT.

I am also having trouble.

If I press any arrow button on either SET or ESC side I will get into the telemetry data screens but I only get the frames and forms but no information (all values = 0 or blank) except for the receiver module.
I can choose the module (once I am inside the screens) by using the up arrow on the SET side.

I cannot understand what I'm doing wrong.

Also my screens do not show the Mikrokopter web address (or the word mikrokopter) anywhere which is different from the descriptions on Holgers site (http://www.mikrokopter.de/ucwiki/en/HoTT).

Another difference. From reading the text I understand that there is supposed to be a screen after the RX SERVO TEST screen in the telemetry, settings & data view screens. In my system the RX SERVO TEST is the last screen.

Other than that my system is working fine. No errors in MKTools, engines start up. I have not flown it yet.

What am I missing?

Thanks
Benji
