4-4 Radio Programming: Adding Contacts
Channel
Your radio operates using frequency-hopping spread-spectrum technology. Each "Channel" is a
group of 50 frequencies. Your radio can transmit and receive on up to 10 channels, but Group
messages are not heard unless users are on the same channel.
NOTE: Each channel can be reused while an established transmission is in progress. All of
the radios may remain on the same channel with no unwanted interference because
DTR radios are based on digital ID based technology.
The home icon on the display indicates that your current scroll list setting is on your channel. Your
radio scans up to 10 groups per channel, plus the Private Groups are received regardless of
channel.
1. Scroll to select Channel and press under Change. The Channel screen appears.
NOTE: The presently selected channel has a to the left of the channel number. Radios on the
same TalkGroup should be set-up on the same channel.
2. Scroll to select a channel and press under Select. The display returns to the previous
screen with the new Channel entered.
Unit Name
Unit ID is transmitted with all voice and text messages. Programming a unique unit name to an ID
causes the radio to recognize any incoming calls from that user or group and display their unit name.
NOTE: A mini keyboard, part number NNTN5491 for DTR550/650 (53967 for DTR410) must be
connected to the radio to enter alphanumeric characters.
1. Scroll to select Name and press under Change. The Name screen appears.
2. Press under Delete to remove characters one at a time or hold to delete all characters.
Use the mini keyboard to enter a new name. After entering the Name, press under Ok
to confirm the entry and to return to the previous screen with the new Name entered.
