If the battery module is not charging:
Check that the Power Supply or mains cable

socket and that any switch is on the on
position. If an extension cable is being used,
it may be fused, so check the fuse.

cable is firmly plugged into the Power
Supply.
Check that the Power Supply is plugged into
the red socket on the underside of the
Charging Dock or Terminal, labelled POWER.

socket and that any switch is on the on
position. If an extension cable is being used,
it may be fused, so check the fuse.
If you have a Power Supply with a separate
electrical mains cable, check that mains
cable is firmly plugged into the Power
Supply.
Check that the Power Supply is plugged into
the red socket on the front panel of the
