SMS phone book
The SMS phone book is where you define the list of GSM cell phone numbers that the M90
can use for SMS messaging. The phone book holds 6 numbers; however, you can dial
more numbers by using an MI pointer. Each phone number can be up to 18 characters
long. You can also add a description to identify who is being called.
Entering numbers in the Phone Book
1. Open the Phone Book by clicking the button on the toolbar.
2. Click on an empty line in the Phone Book shown below, then type in the number.
Note that there are two formats for entering phone numbers shown below. If Limit
to Authorized Phone Numbers is not selected, the M90 can send and receive
SMS messages to/from any number in the Phone Book.
If Limit to Authorized Phone Numbers is selected:
Format 1: The M90 can receive messages from this number. This is because the
number is in full GSM format, including the '+' in front of the country code.
Format 2: The M90 cannot receive messages from this number.
To edit the phone book, click in a number or description, then make your changes.
