Fick ju hem FR Revolution häromdagen, dock spara inte mina patterns när jag stänger av den. Hittade detta på deras hemsida, men jag hänger inte med riktigt:
The Revolution uses a 3.6 volt AA size lithium battery with solder tabs, model TL-5104/P. (Please note there was a typo in the Revolution Owners manual regarding this battery type.) This battery will have a life expectancy of just over a year, due to the extra current draw from the RAM used in it's design. Tip: when replacing the Revolution's battery, you may wish to install a AA battery holder in place of the battery to elliminate any future soldering. Please use good double sided tape to fasten the holder to either the PC board or the bottom chassis. In this case you will then want to use an equivalent battery such as, model ER14505.
