4.1.9  GPS Status 
To aid with installation troubleshooting, this screen presents a continuously-updated message 
describing the state of the GPS data input. One of three messages will be displayed: 
Message  Description 
no GPS RS232 
No  serial GPS  data  is  being  received at  all.  
Check power and wiring.  
data OK, no 
posn 
Valid  serial  data  is  being  received  from  the 
GPS, but the GPS lat/lon is not valid.  This is 
usually due to the GPS antenna not having a 
clear view of the sky. It does indicate that the 
wiring is probably OK. 
GPS data OK 
Valid  serial  data  is  being  received,  and  the 
GPS is reporting a valid position. 
4.1.10 External Pause Signal Type 
The external Play/Pause input signal can be treated as  either  an  “EDGE” or a “LEVEL”.   If 
“EDGE“ is  selected, the play/pause function will  toggle  each time the external button  is 
pressed-and-released. If “LEVEL” is selected, the DMP-300 will remain paused as long as the 
external button is held down, and will resume when the button is released. 
Press  the  button  to  toggle  between “EDGE”  and  “LEVEL”.  The  factory  default value is 
“EDGE”. 
4.1.11 Configuration of the BUSY Output 
The BUSY Output can be configured to go active under one of the following conditions: 
•  Any time a SPEECH track is playing 
•  Any time a MUSIC track is playing 
•  Any time a track is playing, regardless of the track type (factory default value) 
•  BUSY never goes active 
Press the button to cycle through these choices.  When the desired choice is displayed, simply 
cycle power to the DMP-300 or select a different SETUP category.
