4 Insert the back-up battery
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 BT 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.
Please note
Your BT 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.
