Wyatt Tuzo Posted January 22, 2015 Report Share Posted January 22, 2015 Does anyone happen to know what number the 3v TOD/Date internal battery happens to be? I could find out by opening the machine, yes, but I'm hoping to pick up a replacement on my way into my equipment storage. I have contacted SD Tech Support several times, with no response.

Ryan Coomer Posted January 22, 2015 Report Share Posted January 22, 2015 It could be either a 2032 or a 1220, it all depends on your serial number. SN HP15xxxxxxxx / JC03xxxxxxxx and newer use the 2032, SN HP14xxxxxxxx and before use the 1220. Quote Link to comment Share on other sites More sharing options...
Wyatt Tuzo Posted January 22, 2015 Author Report Share Posted January 22, 2015 Thanks a ton, Ryan. Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
Miles Anderson Posted January 22, 2015 Report Share Posted January 22, 2015 they prefer the units to be sent in for service for this battery to be changed because of the possibility of making a mistake somewhere inside the box. Quote Link to comment Share on other sites More sharing options...
Wyatt Tuzo Posted January 22, 2015 Author Report Share Posted January 22, 2015 I did it this morning. It was really simple (including removing/replacing the hot glue glob). Thanks again, Ryan, mine was a 1220 Quote Link to comment Share on other sites More sharing options...
r.paterson Posted January 22, 2015 Report Share Posted January 22, 2015 Hi wyatt I'm going to change mine soon where in unit is it? Do you only need to remove one cover? Many thanks richard Quote Link to comment Share on other sites More sharing options...
Miles Anderson Posted January 22, 2015 Report Share Posted January 22, 2015 I'm also interested in changing it but have held off. until now. is there anything that I need to look out for besides the hot glue glob? Quote Link to comment Share on other sites More sharing options...
Boomboom Posted January 22, 2015 Report Share Posted January 22, 2015 Procedure is on the SD website. Don't have the link but it's there. Quote Link to comment Share on other sites More sharing options...
Wyatt Tuzo Posted January 23, 2015 Author Report Share Posted January 23, 2015 If it's on the SD site, I sure couldn't find it... The 744, yes- the 788, no. Before I delve into this, let me preface by saying that I was both in a time crunch, and am very comfortable with electronics. This isn't difficult to do, just know that you assume all responsibility should something get screwed up. So, here goes: You will have to remove all cover screws plus the strap post screws on the side of your choosing. On my particular serial numbered machine, the battery holder is mounted on a PCB just below the hard drive (between the disk and the input jacks). I used a non-conductive tweeker and a pair of long thin needle-nosed pliers. If you don't have a non-conductive tweeker or the like, use something like a tooth pick. **before opening the case, remove L battery and disconnect any power source** First, gently remove glue glob with pliers Next gently push the battery (from the back corner) toward the opening of its holder with your non-conductive probe. As soon as you've gotten it out enough to grab ahold of the dead batt with the pliers, channel your innermost "Operation" champ and remove that thing. Next, just install your new batt (positive side up, in my case.. Confirm this when removing yours) I decided to add another dollop of hot glue to mine, just to ensure it wouldn't shake loose. The blob of glue really just sits outside the battery holder slot and acts as a retainer. Anyway. Sorry no pics.

Ryan Coomer Posted January 23, 2015 Report Share Posted January 23, 2015 Wyatt- I'm glad I could help. There are actually TWO batteries in the 788t -- one is the Time Of Day battery, the other is the actual timecode battery. The TOD battery is easily accessed and can be swapped quickly as Wyatt described. The Time code battery is a more difficult and time consuming process - it involves removing a circuit board - and should be done at an electronics bench. And Miles is right, it is recommended that a qualified tech do both procedures to avoid any problems. Quote Link to comment Share on other sites More sharing options...
Wyatt Tuzo Posted January 23, 2015 Author Report Share Posted January 23, 2015 Thanks for the heads up Ryan. My TC batt was fine, just my TOD crapping out on me. The bummer is, my machine was recently in for routine maintenance. It seems like a good practice would be for SD to just replace such components whenever they have a machine in for service. The cost could be easily passed to the end user. Oh well Quote Link to comment Share on other sites More sharing options...
Boomboom Posted January 23, 2015 Report Share Posted January 23, 2015 You're totally right Wyatt; it's the 744 int. batt ''how to'' that's on the website, and the instructions for the 788's internal *drive* swap. My mistake... :-/ Quote Link to comment Share on other sites More sharing options...

RPSharman Posted January 26, 2015 Report Share Posted January 26, 2015 My TOD has always drifted significantly, and it's been in twice for other things. You'd think they would swap those out as part of the bench charge. But frankly, it's just not that big of a deal to me. Quote Link to comment Share on other sites More sharing options...
