Section VII
Sending an Emergency Alarm on the Mobile Radio
“Emergency” signals a critical situation where injury to District or other per-
sonnel or destruction of District property is imminent or has already oc-
curred. It should never be used for any other reason.
Note: The emergency button will only work when the radio is positioned in a
trunked talkgroup. The DIRECT 1 and DIRECT 2 positions (C1 & C2) operate in
conventional mode, rendering the emergency button inoperable.
