Example 2: Local Substitution
To dial a long distance call to Beijing requires dialing area code 010 before the local phone number. Using this
feature 1 can be substituted for 010. For example, to call 62213123 would only require dialing 162213123
instead of 01062213123.

Example 3: Add Prefixes
If the dialed number starts with the fixed prefix number, the phone will send out your dialed phone number
adding prefix number automatically.
For example, when users dial “9312”, the device will send out “0079312”.
