OPERATION MANUAL

4.2.9Receiving and Sending Non-voice Messages

The radio can receive and send three types of non-voice messages when operating in digital mode. SMS messages are free text messages sent from one radio to another. With SMS messages, the message (up to 160 characters maximum) is entered using the alpha-numeric keypad and transmitted to the other radio. Predefined messages are common messages among all radios.

A predefined message is selected from the predefined message list (of 20 messages of maximum 20 characters) and the message pointer is transmitted to the other radio.

Status messages are common status settings among all radios. A current status is selected by the radio user (of 30 status settings of maximum 20 characters), and may be sent to another radio. Your current status may also be queried by another user.

Both status and predefined messages rely on the receiving radio’s database to determine the message displayed. The message characters are not sent, instead only a pointer of which message should be displayed is sent. For proper status and predefined messaging operation, both the receiving and transmitting radios should be using the same message database.
