Stannah 420 product support

Typically, if your Stannah 420 stairlift batteries are not charging properly you will hear your stairlift beep.

• Check the wall switch is set to the on position
• Check to see if there is a power cut in your home
• If you have a hinged rail fitted, press and hold the ‘up’ arrow on the remote calling control to make sure the hinged rail is fully raised.

If you cannot correct the fault, you can switch off the beeper by turning the master power switch to the off position. Then, please call your local Stannah service branch.

If the power light is off:

• Check the master power switch is set to on
  
  
  
  
  
• The master power switch is on the rear of the chair and should normally be left on)

If the power light is on:

• Check the chair is swivelled back to its travelling position
• Check there is no obstruction to the safetly edges; if there is, remove the obstruction
• Check the hinged rail is fully lowered; if installed

If your remote calling controls stop working, then check the batteries. With average use, you can expect the batteries to last for about a year. 

It’s easy to check the battery power at any time. Press down on one of the arrow buttons, and the light around the buttons will tell you how much power is left. You will notice that the lights are on constantly when the battery is low, and no light shows if the batteries have no power.

Refer to your user manual to find out how to change the battery. 

If the above hasn't helped then you can refer to your specific user manual for more information.
