Performing a factory
reset
If the T23 is moved to another location you may
need to clear the DAB memory and presets in
order to receive any new local stations. In this
case perform a factory reset as follows:
•
Switch the T23 to standby.
•
While holding down the V button press
STANDBY until the display shows:
Set Factory Default?
1:FM 2:DAB 3:FM+DAB
•
Using the remote control press 1 to use FM
only, 2 to use DAB only, or 3 to use FM and
DAB.
The display will confirm that a factory reset has
been performed.
WARNING: This will delete all the DAB and FM
presets and settings.
IR input
The T23 normally receives remote control
commands from an infra-red eye on the front
panel. If you want to control the T23 remotely
you can connect the IR socket on the back panel
to an infra-red eye or multi-room system infra-red
output.
To enable the IR socket
•
Turn on the main power switch while holding
down the i button on the front panel.
The display will show:
BACK IR
RS232
The RS232 connector allows your dealer to
upgrade the firmware on your T23, or control
the T23 as part of a multi-room system. Do not
connect anything to this socket unless instructed
by your dealer.
Connecting an aerial
The type of aerial you need for DAB and/or FM
reception depends on the quality of the signal in
your area and your listening preferences.
For best results from both DAB and FM reception
you will need separate DAB and FM aerials, with
an aerial combiner to combine the signals from
both aerials into the connector on the back panel
of the T23.
DAB
In an area with good reception you should get
good results with a simple dipole aerial, with
two elements or wires arranged in a T. The aerial
should be mounted with the elements pointing
vertically as the transmissions are vertically
polarised.
FM
In an area of strong FM reception a dipole aerial
should also give good results with FM. Arrange
the elements horizontally as FM receptions are
horizontally polarised.
In an area of poor reception you will need a roof
or loft mounted FM aerial; contact your local
dealer for information and advice.
