[duylong187]

Hi all

I have a DVR-RT602HS and i tried to add the battery expand because the clock will be lost after 12h when no power. This is a steps i did:
1/ open the DVR and take to piece the VCR chasiss
2/ find the capacitor C3016 of IC3002 in VCR MICON board (check at service manual) and weilding the 2 electric wire to this point (red line for anode and black line for cathode)
3/ simplex combination 4 battery charge (AA) about 5.4v and weilding to that electric wire
Now The clock of my DVR-RT602H become stanby more than 48h after cut off the power

I hope someboby maybe share the experience in common with me
Cheers!

P/S: thanks to Mr.Hakan give me the service manual of my DVR
