Provident Fund Employer's Contribution

Hi! Needed some information regarding Employers Contribution to PF. We started PF for our organisation in Oct last year. Since we had to pay some arrears, we restricted Employer's contribution to Rs 780/-. However now we want to change it to 12% of basic, can someone one guide me as to what formalities we need to fullfil with the PF department to shift from 780 to 12% of baisc.
Thanks in advance for your help.
