Motorola DTR SERIES DTR550 - Manual (Page 21)

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

The radio chirps and the display briefly shows Motorola.

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.
