Taking a look at our line up I am not see that we have offered that specific model so we're not to provide you the manual through our resources. Not to worry, we still want to help any way that we can. I have provided a link that will allow you to look up your device to access the manual if available.
For now, taking a look at some external resources we may be able to lend a hand. From what we have found you should be able to go into the Contacts, select Edit, highlight a specific number and then press Options, then select Set Speed Dial, select a digit to assign it to and then press Save.
Give this a shot and keep us posted.
