Using the Intercom

The intercom feature lets you call optional WHAM x 4 microphones connected to the
radio. You can select and call one microphone, a group of microphones, or each
microphone connected to the radio.
Notes:
• WHAM x 4 microphone users can also call each other and the radio.
• WHAM x 4 microphone users cannot receive MRN signals received by the radio.
• If the radio receives a DSC call while the radio is set to the intercom mode, infor-
mation about the call appears on the display for about 5 seconds.
• If any WHAM x 4 microphone user cannot connect with the radio, intercom does
not work and the radio sounds an error tone.
