Things you will need to program the phone
Before programming the telephone you will need to have another telephone with a keypad to program
the TS351-MDX.
Programming steps
1. Plug the telephone into the wall jack and make sure the handset is hung up.
2. Take the other telephone with the key pad and call the line the TS351-MDX is connected to.
3. When the TS351 rings, answer it and leave the handset offhook.
4. Using the other telephone with the keypad dial #0*, you will hear one beep.
You are now in program mode and can enter any valid program register. If you enter the
password incorrectly you will have to repeat steps 2 and 3. To exit program mode dial 99 wait
for beep and hang up. At any time you here 4 beeps this means a program entry was incorrect.
