blank
Countertop models (T4210/T4220/T4230)
Check that the Power Supply or mains cable is
plugged into a working electrical wall 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 connected and
locked into the red socket on the back of the
terminal labelled POWER.
Mobile models (M4230/M4240)
Ensure a battery module is fitted.
Hold down the blue FUNCTION button on the
terminal keypad for eight seconds.
If the terminal does not beep and turn on:
Connect the Power Supply into the red socket
on the terminal labelled POWER, or place on a
powered Charging Dock.
Hold down the blue FUNCTION button on the
terminal keypad for eight seconds.
If the terminal still does not beep and turn on:
Check that the Power Supply or mains cable is
plugged into a working electrical wall 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.
Hold down the blue FUNCTION button on the
terminal keypad for eight seconds.
PLEASE NOTE: If problems persist, please call the
helpdesk.
