Tip:
The Jog Dial is for any kind of Intercom related function, and the Phone Button is for any
functions of mobile phone. With this reason, as far as intercom function is concerned, the Jog
Dial is used for a positive manner of action such as enabling, and the Phone Button is for a
negative manner of action such as disabling. Vice versa for the mobile phone functions.
Intercom Failure
When you try to start an intercom conversation with an Intercom Friend who is already having
an intercom conversation with other Intercom Friend or a mobile phone call with another
person, you will hear a low tone double beep signifying a busy signal. In this case, you have
to try again later. On the other hand, the Intercom Friend will hear a high tone double beep
alerting them that there is an incoming intercom call.
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 SPH10
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.
Stereo Music
You can listen to stereo music in either way: with the enclosed stereo audio cable or by
Bluetooth wireless stereo.
1. By Stereo Audio Cable
Plug your stereo MP3 player directly to the SPH10 by using the enclosed 3.5mm stereo
audio jack cable. To adjust the volume, rotate the Jog Dial on the headset. You may
adjust the volume on the MP3 player also.
