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.
Making a Call
1. Choose a contact from your Scroll List, Contacts, or Recent Call List.
2. Press and hold the PTT button. Begin speaking after the radio emits the talk permit tone. To
maximize clarity, hold the radio two-to-three inches away from your mouth.
3. Release the PTT button to listen.
NOTE: If “User Not Available” displays, the recipient is either: In a Call, Out of Range, or Turned Off.
Press to cancel and then try the call again. When contacting a group, at least one
member must be available for the call to be successful.
