-These pagers were available in the former POCSAG net by Deutsche Telekom AG and later by e*message. The HF part of the receiver is identical to [[skyperdescription|Skypers]]. The modification for 439.9875 MHz is thus the same. The shortcome is that the display is much smaller and there is no built-in function for setting time and date autmatically. In addition the date only allows years up to (20)13 starting from (19)94 to be set. This has to be done by hand and is lost on longer absence of battery power.+These pagers were available in the former POCSAG net by Deutsche Telekom AG and later by e*cityruf.

 When this is finished you can improve reception by tuning the antenna circuit to maximum signal strength. Therefore conncect your scope to pin 12 and tune to maximum signal by turning trimmer CT1 carefully. ​ When this is finished you can improve reception by tuning the antenna circuit to maximum signal strength.

-If all is done your Promo should receive messages from DAPNET network. You can test that using the "Send Message"​ function of UniPager which circumvents the DAPNET connection and sends out POCSAG calls directly.+If all is done your Primo should receive messages from DAPNET network.

-The Primo pagers obviously share some similarities with Skypers. ​There is a connector ​for external programming which probably ​is the same as found on Skypers. ​This needs further investigation.+The Primo pagers obviously share some similarities with Skypers. ​

 +==== Reading programmed RICs ==== 
 + 
 +If you just want to know which RIC(s) are programmed in your Primo pager there is a special key combination that was deteced by DK7DB. Turn the pager off and press "​M"​ twice. It will show the programmed RICs 1 to 3.

 +==== Hardware ==== 
 + 
 +The connector ​on the display PCB is identical to the [[skyperdescription#​hardware|interface ​found on Skypers]]. The connector looks as follows:

 + 
 +==== Software ==== 
 + 
 +Using the same programmer as for Skypers ([[skyperdescription#​hardware|linked here]]) you read at least read the RIC from the pager. After starting the software you have to load the correct .ROM file. In this case we used 20bd-a.rom and after pressing F1 to read the pager the correct RIC was displayed.

 + 
 +Wrting the pager has not been tested as we are not sure if the .rom file is 100% correct yet.

 +==== Anleitung ==== 
 + 
 +Zum bedienen des Pagers ist eine Bedienungsanleitung bei "​E*Cityruf"​ zu finden.
