6.26 MAKING SELECTIVE CALLS

Selective calling is a feature that allows two radio units to obtain and utilize an independent voice path for

a private call. Radios can be configured to both initiate and receive selective calls or to only receive

selective calls.

In the OpenSky system, a source radio can be configured to initiate selective calls through a pre-

programmed list in memory. This method uses the “speed dial list” set up by the OpenSky network

administrator and provisioned as part of the registration process.

In addition, a properly equipped source radio can initiate a selective call to any radio in the system by

entering the ten-digit voice user ID (which looks like a telephone number) of the target device. Entering a

selective call number without using the speed dial feature requires a system model control head (Figure

6-1). See section 6.13 for more detail.

Selective calls are terminated if an emergency is declared. The network limits selective

calls to ten (10) minutes maximum.

1. Press *8 on the keypad.

2. Enter the number of the radio to be called (e.g., 027-001-0006). If the region number (first 3 digits;

027 in this example) is the same as this radio’s region number, these digits do not need to be entered.

Likewise, if the region and agency numbers (first 6 digits; 027-001 in this example) are the same as

this radio’s numbers, these digits do not need to be entered. Leading zeros can also be ignored.

3. Press and release the # key.

4. Wait approximately two (2) seconds.

5. Press and release the PTT button to initiate the selective call request. When the called party accepts

the call, press the PTT again and begin speaking.

Speed dial numbers are defined and provisioned by the OpenSky network administrator

and cannot be manually entered into the radio by the user. Contact the administrator if

changes to the speed dial list are required.
