TYPE 3 MESSAGE CLASS
The SmartOne will use the Type 3 message class for the following message types:
• Diagnostic Message – Subtype 21.
• Replace Battery Message – Subtype 22.
• Contact Service Provider Message – Subtype 23.
DIAGNOSTIC MESSAGE
The Diagnostic Message includes battery status, GPS average acquisition time, GPS fails and number of
transmissions since the last Diagnostic Message.
Appendix I has an example of a decoded Diagnostic Message.
The format and fields of the SmartOne Diagnostic Message is shown in table 8 below.
REPLACE BATTERY MESSAGE
The Replace Battery message has a format almost identical to the Diagnostic message. If enabled by the user, the
Replace Battery message will be sent by the SmartOne when the battery charge level is at or below the replace
battery advisement level. The message will be repeated at an interval configurable by the user for as long as the
battery remains below the advisement level. The default configuration is for the Replace Battery message to be
enabled and to be transmitted once per day when the battery is low.
