Chapter 2 General Radio Operations
Your radio is ready for use after a fully-charged battery has been installed. However, your radio 
should be programmed in order to be fully compatible with any existing DTR Series radios and to 
fully utilize all radio features. 
Refer to Chapter 3 - Advanced Radio Operations.
Turning Your Radio On or Off
Press 
 to turn your radio on.
The radio chirps and the display briefly shows Motorola.
The display shows the radio Unit ID or Name, current Scroll list setting, time, date, and the available 
Option key selections. If the radio has been assigned a unique Unit Name, the name will display 
rather than the Unit ID for both the radio and any Contacts.
Press and hold 
 to turn the radio off.
