-These pagers normally come with a (more or less) hard-coded RIC. It can be found on a small label on the back side. It is not! the "Skyper Nr."  but the second part of the "ID Nr.". It is contains 7 digits of which the last four are underlined (has been used as a PIN in the former life of those units).

+These units support automatic time synchronisation to the DAPNET transmitter/core as well as rubrics messages. The latter need an activation which can be sent out from the hampager portal (see "rubrics"); the activation is stored in non-volatile memory.
+The rubrics list, the rubrics contents and your individual rubrics subscription however are stored in SRAM and are lost if your battery runs out of power. If this happens, don't worry - the rubrics list is periodically transmitted by the DAPNET core. Just wait until the Skyper has received the list (this may take several hours) and you are able to subscribe to the rubrics again. If you want to avoid this, be sure to replace a weak battery in time.
+==== Skyper versions ====
+There are various versions of Skypers (e.g. Skyper 1, Skyper 2, Skyper 2/A...). The hardware is identical, but they have different firmware features (and bugs...). For example, the Skyper 2 and up versions have auto-repeat/scrolling in the rubrics list and automatic time resynchronization every Sunday morning. They also turn on automatically after inserting a new battery - the Skyper 1 must be turned on by holding the "M" key. There are a lot more differences between the firmware versions, which are related to closed user groups, overwriting messages etc... DAPNET currently does not use these features, so all Skyper versions are suitable. The hardware modification procedure is always the same.

+===== Separating the display board from the case =====
+Should you have trouble with the silicone rubber keyboard or with the microswitches underneath
+you may want to take display board and case of your Skyper apart.
+Another reason to do this may be that you want to clean the display and case from the inside
+or to replace a damaged Skyper case with a better one.
+{{:p6160003y.jpg|}}
+One straightforward way to do this is the one DK7TD describes using a small screwdriver.
+For an experienced user who knows what he's doing this can be the way to go.
+But there is some risk in it especially if you are doing this for the first time.
+If you are unlucky you may end up with a display where some lines of pixels are missing
+when you power up your Skyper afterwards.
+What has happened? Please keep in mind that Skyper hardware is around 20 years old stuff.
+While pulling out the display board this way the flexible board connector
+atop of the LCD display may move and some pins can get loose.
+Should this ever happen there is no known way to fix it.
+{{:p6160026y.jpg|}}
+After experiencing this twice up to now (I have modified >20 Skyper) I asked myself:
+Is there a safer way to work on the display board?
+YES there is one.
+You can fix the LCD to the display board applying a few drops of 2K glue at the positions
+shown below.
+After hardening for some hours you can pull out the board using a simple smartphone
+opening tool at the two shown positions.
+One tool is enough - you don't need two of them.

+If you did the soldering and the modification on the RF board of your Skyper yourself
+it should be no problem for you to get the old microswitches out and new ones in.
+For me it was difficult to get them here in Germany. The dimensions are listed below.
+I found them on eBay. They are quite inexpensive even if you have to order 100 pcs in China.
+In my opinion its a good idea to replace all 4 microswitches even if only one
+is faulty. So the look and feel is the same on all 4 keys afterwards.

+===== Used time zone =====
+The skyper gets its time settings "over the air". Time is broadcasted via RIC 2504 (hard encoded) and in DAPNET UTC is used (and cannot be changed in the skyper itself).
