TELEVISION _ Service Mode _ Adjustment Details.
All adjustments to this
chassis, except for focus, are carried out in the Service Mode. The Service Mode is provided to enable the
engineer to correctly set up the receiver to the CRT fitted in the set. Note that these adjustments may vary from one
receiver to another.
To enter the Service Mode,
carry out the following procedure.
1 Connect a test pattern to the antenna terminal.
2 Tune the receiver to this signal.
3 Turn the receiver off using the mains switch.
4 Press volume down and channel up buttons on the front of the receiver at the same time.
5 Keeping these buttons pressed, turn the mains on.
6 When the set starts up it will be in Service Mode.
7 Release the two buttons.

6 When the set starts up it will be in Service Mode.
7 Release the two buttons.
> Use the channel up and down
buttons to move between the options.
> Use the volume control buttons to change the data.
> To store the data, use the stand-by button on the remote control.
> To exit the Service Mode, turn the receiver off using the mains switch.
> Use the volume control buttons to change the data.
> To store the data, use the stand-by button on the remote control.
> To exit the Service Mode, turn the receiver off using the mains switch.
When the Service Mode is
entered the On Screen Display appears.
The figures displayed in the
XXXX locations are hexadecimal representations of the number of times that
particular function has been executed. For example if the hexadecimal number
displayed after SW on was 0E4A, this would correspond to the receiver being
turned on 3658 times. The figure displayed in the **_**x** location is the
EPROM version.

Adjust Level
Turn your Sub-woofer-Level Control up to the “5” position (halfway). If no sound emanates from the sub-woofer, check the AC-line cord and input cables. Are the connectors on the cables making proper contact?
Is the AC plug connected to a “live” receptacle?
Has the Power Switch been pressed to the “On” position?
Once you have confirmed that the sub-woofer is active, proceed by playing a CD, record or cassette. Use a selection that has ample bass information.
Set the overall volume control of the pre-amplifier or stereo to a comfortable level. Adjust the Sub-woofer-Level Control until you obtain a pleasing blend of bass. Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range. Many users have a tendency to set the sub-woofer volume too loud, adhering to the belief that a sub-woofer is there to produce lots of bass. This is not entirely true. A sub-woofer is there to enhance bass, extending the response of the entire system so the bass can be felt as well as heard. However, overall balance must be maintained or the music will not sound natural. An experienced listener will set the volume of the sub-woofer so its impact on bass response is always there but never obtrusive.

Phase Control
The Phase Switch determines whether the sub-woofer speaker’s piston-like action moves in and out with the main speakers (0˚), or opposite the main speakers (180˚). Proper phase adjustment depends on several variables such as room size, sub-woofer placement and listener position.
Adjust the phase switch to maximize bass output at the listening position. Crossover Adjustments The Crossover Adjustment Control determines the highest frequency at which the sub-woofer reproduces sounds. If your main speakers can comfortably reproduce some low-frequency sounds, set this control to a lower frequency setting, between 50Hz and 100Hz. This will concentrate the sub-woofer’s efforts on the ultra deep bass sounds required by today’s films and music. If you are using smaller bookshelf speakers that do not extend to the lower bass frequencies, set the Crossover Adjustment Control to a higher setting, between 120Hz and 150Hz.
NOTE: This control will have no effect if the LFE Input ¢ is used. If you have a Dolby Digital or DTS processor/receiver, the Low-Pass Frequency is set by the processor/receiver. Consult your owner’s manual to learn how to view or change this setting.
