Stairlift (Grassmoor, Chesterfield)

Straight stairlift, length 11 steps plus onto landing. 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 could just be batteries, but if not, you can google "Brooks stairlift error code H4", and find other suggested remedies. You must dismantle and collect from Grassmoor, Chesterfield.
