Messages will remain viewable on your IHD until they expire.
Expiry times are set by your service provider. Expired messages
are not retrievable.
Some messages may require that you acknowledge them and will
instruct you to do so. Press <L> and <R> at the same time to
acknowledge the message.
3.4 Understanding the lights on your IHD
Your IHD includes three Light Emitting Diodes (LEDs) which it
uses to indicate the presence of new messages and the current
relative cost of electricity.
Note: the LEDs will continue to function while the IHD is asleep.
When a new or unacknowledged message is available on your
IHD, the LEDs will show this by simultaneously blinking once
every 5 seconds. The LEDs will continue to blink until you have
acknowledged this message or changed to another screen.
When no new messages are present, the LEDS will indicate the
current relative cost of electricity. A pulsing LED indicates the
tariff period you are currently in, while a blinking LED in
conjunction with a pulsing LED indicates an upcoming tariff
period change. The colour of the blinking LED indicates the
upcoming tariff period. The special case of Critical Peak Pricing
(CPP) is indicated when the red LED is blinking on its own. The
following table clearly defines the LEDs' behaviour for your
service providers tariff structure.
