3.5.1.1 Audible Alerts: When EAB is depressed, Audible Alerts are emitted.
Alert Tones: Alert tones are the audio signal transmitted to other HTs
within range of the transmitting HT notifying others a member has
activated his/her EA. This signal alerts members of a Mayday or
Urgent situation. There are two types of alert tones; Impolite and
Polite. The APX8000XE transmits One (1)-Impolite and Two (2)-
Polite Alerts.
Impolite Alert - An impolite call is when the radio sends a
transmission even when the channel is busy with other radio traffic,
however it will NOT preempt any ongoing transmissions.
Note: Due to radio frequency (RF) anomalies, some radios may not
receive the emergency alert.
building construction, height, terrain and other factors can
contribute to the individual member's radio ability to receive
the transmitting member's EA.
Polite Alert - A polite call is when the radio sends a transmission
when the channel is not busy with other radio traffic. Thereby, increasing
the likelihood that other members will receive Emergency alert.
 Approximately 8 seconds after the impolite transmission,
the Polite Alert is sent. Therefore, the Polite Alert may be
more than 8 seconds after the Impolite Alert tone if other
members are transmitting.
transmit 2 Polite Alerts to attempt to reach as many
members as possible.
 All 3 Alerts will be transmitted, regardless if members are
transmitting or receiving messages. The Impolite Alert will
go out first, followed by 2 Polite Alerts when the channel is
clear.
Beacon Tone: Manual activation of a radio EA, will initiate an audible
Beacon transmitted from that radio. This beacon is used to locate
member that activated the EA. This audible beacon is emitted from
members HT until it is reset by member.
Reset EA: EA may be reset by depressing EAB for 2 seconds, or by
turning HT off and then back on.
