Before inserting the back-up battery
you must ensure that your unit is
connected to the mains power.
The back-up battery (9V alkaline not
supplied) ensures that all settings and
messages are saved for up to six hours
in the event of a power cut.
If the back-up battery runs out, or no
battery is fitted, then in the event of a
power failure your Response 75 will
revert to its original settings and
messages will be lost.
If the battery is low the “Battery Low”
light will come on.
Insert a 9V alkaline battery into the
battery compartment.
You will now be able to use your
telephone as normal.
Your Response 75 is now ready to use.

Please note
Your Response 75 Plus battery low light,
located beside the display, indicates
back-up battery strength.
The LED will light up when the battery
is low. It also remains lit when no
back-up battery is inserted.
