Stairlift (Grassmoor, Chesterfield)

Straight stairlift, length 12 feet. Purchased 2014 but not been used for 5 years so will probably need new batteries. Has the manual and a remote control to call chair up or down. When switched on now, it shows error code H4, which is stopping it working, which could just be batteries as it worked perfectly when last used. You can also google "Brooks stairlift error code H4", and find other suggested remedies. You must collect from Grassmoor, Chesterfield. Giving away due to house sale.
