RC-10 : Very good once you get it working

I originally wrote a poor review as the unit would not work with my DR-40. There are no clear instructions with the unit itself other than to refer to the DR-40 user manual, and the multi-lingual manual supplied with the DR-40 has no information about use. However if you download the .pdf for your recorder from the Tascam website you get a much more detailed and comprehensive manual which does include the setup instructions, which are simplicity itself and took less than a minute to be up and working. There are separate settings for the footswitch and manual remote options and my DR-40 must have been set by default to the footswitch setting. Works well and is simple to use.
