17. INTERCOM FAILURE
When you try to start an intercom conversation with an 
intercom friend who is already having a conference 
intercom with other riders or a mobile phone call, 
you will hear a low tone double beep signifying an 
intercom busy signal. In this case, you have to try 
again later. 
18. INTERCOM RECONNECTION
If your intercom friend goes out of range while having 
an intercom conversation, you may hear static noise 
and eventually the intercom will be disconnected. In 
this case, the SPH10H automatically tries to reconnect 
the intercom every 8 seconds and you will hear high 
tone double beeps until the intercom is reestablished. 
If you don’t want to make a reconnection, tap the Jog 
Dial to stop the attempt.
