Emergency Call
The emergency call button should only be activated in emergencies where there is a
‘grave or imminent danger to life’, or the use of the radio presents a serious security
risk.
For all other emergencies, voice contact should be used.
When the emergency button is pressed continuously for 5 seconds, the emergency
signal will be sent to all radios within range and on the same frequency as the radio
whose emergency button is pressed.
It is important to switch off other VHF radios in company with the activated unit so
that no-one is aware that an emergency signal is being transmitted.
Example: In a vehicle which has been commandeered by a person(s) for subversive
reasons.
All radios will receive the emergency tone sequence for 20 seconds, with a 20-second
interruption, displaying the user ID.
Example: 140319802 or CS802. (Refer to the ‘UN Callsign and Selcall Allocation
Table’ for a break down of the user ID).
The microphone on the radio issuing the emergency call will also be activated
The radio issuing the Emergency Call will look deactivated, no messages will be
displayed and the speaker of the radio will be quiet, the emergency tone will still be
transmitted even if the radio is physically turned off.
After issuing an Emergency Call, the issuing radio cannot be used, until the battery is
removed or the power source is disconnected.
Selcall
This is where the big difference between the GP380/GM360 and older VHF radios
such as the Motorola GP/GM300 series can be found. The GP380 radio can call any
individual radio in the network as well as predefined groups and users. This could be
users or groups like “Head TC/ICT or All vehicles”.
All radios have been pre-programmed with an address-book which is divided into two
parts.
The first part, the “Contact List” contains addresses of different locations and
agencies (the system has been designed to accept other UN agencies and NGO’s).
“IRA, TF, THN” is one example, this being a station in Tehran, Iran that belongs to
WFP.
The second part is the “Status List” which identifies the group to be called within the
chosen location and agency, e.g. “All Logistics” will call all radios belonging to staff
working in logistics.
