Incoming Call Beep (DIP Switch 3)
Incoming calls are always indicated by a red-flashing call key. If you also want in-
coming call beep in headphones, set DIP switch 3 to the Open position (default). DIP
switch 3 must also be in the Open position if you want to activate incoming call beep
to the speaker using DIP switch 5.
Dynamic Microphone Type Selection (DIP Switch 4)
If you will be using a headset, telephone-style handset, or dynamic handheld
microphone, and the specifications indicate the microphone type is balanced, leave
DIP switch 4 in the Open (default) position. If the specifications indicate an unbal-
anced microphone set this switch to the Closed position. If you are not sure, leave the
switch in the Open position for now, then try both positions during operation. Use the
position that produces the best audio quality at other stations.
