Step: 1 (500ms) When transmitting across the relay and
retransmitting, after the transmitter releases the PTT key, the
two-way radio enters receiving state. Due to the delay of
relay, the instant signal transmitted by the relay can be
received. The value of the menu item shall be adjusted to
ensure that no noise of this two-way radio is generated when
transmitting across the relay, so as to confirm whether the
relay is operating. The menu item shall be set OFF.
