General Radio Operations: Receiving and Making Calls

2-3

 

 

Receiving and Making Calls

NOTE: Your DTR Series radio must be programmed to be fully compatible with other DTR Series radios and fully utilize all radio features. Refer to Chapter 3 - Advanced Radio Operations.

Types of Calls

Your radio can make and receive three different types of voice calls:

•PublicGroup – One-to-many communication to all radios set to your channel and PublicGroup number. All DTR Series radios are factory programmed with 2 to 5 PublicGroups.

•Private – One-to-one communication with another radio, requires adding a user to the Contacts List.

•PrivateGroup – One-to-many communication to only radios in your group. Requires adding all members to your Contact List then cloning the group (either over the air or with the RRDN5378 cloning cable) to member radios. Offers a higher level of privacy than a PublicGroup.

Receiving a Call

When a call is received, the radio chirps and the display shows the call type and transmitting caller’s user ID or name.
