 You need an interface that supplies 3v0 to the pager to activate its programming mode. A small SMD PCB that fits into a DB9 connector case is described here: https://github.com/dk4pa/SKYPER_PROGRAMMER. Power is drawn from a USB port and converted to 3v0. A small amount of PCBs is available at cost from the authors. Please contact DK4PA or DF2ET. The Skyper has a programming interface which is located inside the battery compartment. It requires the wiring of GND, 3v0 as well as RX/TX lines. All experiments to build some sort of plug failed so far. Thus we normally solder the 4 wires to the pads after opening the case.

+===== Removing the display from the case =====
+The display is mounted in the case with clips. You can use a small screwdriver to *carefully* pull away the case from the display and lift the display (each side after each other)

+===== Preset of display contrast =====
+Have you ever asked yourself what this tiny trimpot on the rear side of the display board does?
+Well if your display is working fine and contrast setting can be done via setup menu there is
+probably no need to.
+The initial setting was done by the manufacturer and normally this should work all right.
+Turning this trimpot clockwise will increase display contrast while turning counterclockwise will decrease contrast.
+Please be aware that this is a very coarse setting. The fine adjustment is done in the Skyper setup menu using the up and down keys.
