GPS / RFT Connector 
LS1 - Piezo sounder  
Set, Adj, Alarm Buttons 
C9 - 0.1F Supercapacitor 
C10, C13 - 100nF 
D4 - Green GPS / RFT LED 
D5 - Yellow Alarm LED 

Note that if you won't be using a Radio Time Receiver Module, then you 
can omit the GPS / RFT Connector, D4 and C13.

 

C9 is a polarised component. The arrows on the component body should 
match the arrows on the PCB marking.

 

 

 

The longer lead of each LED goes in the hole marked '+'.
