Using #2 in register 01 adds .5 seconds. So, added 4 times to add a delay of 2 seconds, as shown in the example below:
For example, program it to auto dial 3055585577 pause (2 seconds) then dial 1:
Step 1) Enter # 0 *(you should hear a 'Beep' sound) -- entering the programming mode
Step 2) Enter 01 (you should hear a 'Beep' sound) -- entering function code to restrict numbers
Step 3) Enter 3055585577 #2#2#2#2 1
Step 4) Hang-up or press ## -- exit
