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. | You need an interface that supplies 3v0 to the pager to activate its programming mode.

+ | ===== 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. | ||
