9.25 MAKING SELECTIVE CALLS
Selective calling is the capability for two voice radio units to obtain and use an independent talk path for a
unit-to-unit call. A properly equipped radio can initiate a selective call to any radio in the system that is
also programmed for selective calls.
In the OpenSky system, a radio can be configured to initiate selective calls through a pre-programmed list
in memory called a speed dial list. Alternatively, a properly configured radio can initiate a selective call
to any radio in the system by entering the ten-digit User ID (similar to a telephone number) of the target
radio. Some radios are configured to only receive (not initiate) selective calls.
Selective calls are terminated if an emergency is declared. The network limits selective
calls to ten (10) minutes maximum.
If a Selective Call is attempted without physical registration, No Priv is displayed.
9.25.1 Manually Dialing a Selective Call (P7370 Only)
1. Enter *8, the User ID number of the user being called, and the # key (no dashes or spaces). Note that
this feature must be enabled by the administrator.
*8<destination user id>#
A shortened User ID number can be dialed using the following guidelines:
• If the radio being called is in the same region and agency – enter only the last four digits.
• If the radio being called is in the same region, but a different agency – enter the last seven digits.
• If the radio being called is in another region or if the area is unknown – enter all ten digits.
2. Press the PTT (and release) to ring the other user.
The ring tone is sounded.
If the other user accepts the call, the called user’s alias will appear in initiating caller’s display. The
two are now in a unit-to-unit call until one ends the call, the call is terminated due to an initiated
emergency, or the maximum time limit of ten (10) minutes is reached.
If the called radio is busy, BUSY will appear in the second line of the display.
