The TX-111 is the latest design remote for the Dynatron 3 Series (D3400, D3600 & D3800). The remote is powered by 2 CR2016 Coin shaped batteries. Typically I would expect the batteries to be good for around 3 however excessive usage may shorten this time.
To change the batteries the remote case can be opened by using a flat blade screw driver to prize the case apart. Care should be taken not to bend the + terminal that holds the batteries in place as doing so may cause a loose contact.
If the remote does become intermittent then it is worth using your thumb to bend the + terminal down and hopefully this will fix the problem. It is worth saying that this is not a big issue and I have only come across 2 which I have fixed this way in the past 2 years so on the whole it is a very reliable remote.
