Abstract
Abstract When a portable radio (110) receives a transmission from a mobile radio (105), the portable radio (110) mutes a speaker volume of the portable radio (110) for a duration of the transmission from the mobile radio (105). In an arrangement of the mobile radio (105) and the portable radio (110) where both radios transmit and receive on a same communication resource channel and both radios are in close proximity, acoustic feedback may be avoided.
