The battery is a lithium CR-2032 but you need the one with solder tags 
(RS catalogue I think). It is got at by removing the screw under the 
rubber foot top right looking at the rear of the unit - gently prising 
apart the case wide a wide screwdriver. The case separates from the top 
(as I remember!).
A fiddly job but only 10mins or so.
There are threads on the Yaesu group about improving the quality of the 
recording unit - I had a quick look at the suggested mods and changed my 
mind !!  Too small components and operator too old !!
