Tuning

Automatic tuning

When the unit is turned on for the first time, all settings will be default settings. The settings can be
changed according to your preference. When the unit is turned off the next time, these settings will
naturally be saved as the new default settings. This also applies if you unplug the unit.

When the unit has been turned on, channels must be saved. This is done by means of the
autotune function.

1. 

To use the autotune function through the front panel controls, press the AUTOTUNE button. All

available channels on the current tuner band will be saved.

2. 

You can also press the AUTOTUNE button on the remote control.

Note:

 

Weak stations may also be stored in memory, so manual memory presetting may be needed

in order to have better receiving.

Manual tuning

1. 

If you want to manual tune a channel, you must press the tune + or - button on the remote

control, or turn the tuning knob on the front panel. For every push on the button, the frequency
will change 0,05MHz on FM and 9 Khz on AM.

2. 

To store the manually tuned channel, simply press the Memory button on the front panel or the

Memo button on the remote. The channel will then be stored on the current preset.

Selecting presets

Channels that have been saved can be selected either by means of the and Preset -
buttons on the remote control or on the front panel, or by the direct access buttons (1-5 on the front
panel or 1-9 on the remote control).

Stereo and Mono

In some areas not all stations can be recieved noise free, because it is not possible to get a strong
enough antenna signal.
In this case there will be a lot of noise on some radio stations. It is possible to reduce the noise quite
a bit by listening to the radio station in mono instead of in stereo. This can make the radio station
acceptable to listen to. Change to mono by pressing the ST/MO button on the remote or the ST/
MONO button on the front panel. To change back to stereo again, simply press the button once again.

Reset

This tuner can be reset. This is used to delete channels stored in the unit. Press the RESET button on
the front panel to reset the unit.
