Menus / Set Up

[AutoSelect]
To hear a channel without selecting it, the AutoSelect function can be enabled. Once activated,
the system searches for a channel with audio on it at a rate of 6 channels per second. Once audio is found,
the channel will lock until there is absolutely no audio for 50 seconds.

To activate AutoSelect, press and hold button for longer than 1 second. Once button is released, [menu] will be 
entered. Select each menu choice by pressing the button. LED 1 ( bottom LED ) is for AutoSelect options.
After 1 second, the option can be selected: [ Off ] or [AutoSelect] on. 
Be sure to select immediately or a timeout will occur and return focus to the channel (main) menu.

[Hour Timer]
Also called [Shutdown timer]. This is a safe guard against unnecessarily using battery power due to the unit being left on.
The timer will shut system down after the preset time. All memories/presets will be retained.
To enable Hour Timer, enter menu mode. To enter Menu Mode, press and hold button for > 1 second. Once LEDS flash,
[Menu] will be announced and the [Shutdown Timer] can be selected. LEDs will flash again.
select between: [OFF] [1/2 hour] [1 hour] [2 hours] [3 hours] [4 hours] ( 4 hours is actually 3:50 )
After you pause selection, the last announced value will be entered.

[Restart]
Once hour timer has turned off system, the only way to turn it back on is to turn off volume switch, wait 2 seconds,
then turn it back on. [Welcome] means system is restarted. This may take up to 2 seconds.

[Presets]
Like most modern systems, the SDS stereo has some EQ audio presets. The default preset is "Classical".(1)
Others are:
(2) Rock, with a higher bass, medium sub, lower midrange, high tweeter, and 20% MPX
(3) Movie, with high sub, lower bass, higher midrange to rear and tweeter with 80% MPX
(4) Dance, with higher Sub, low bass, flat midrange and slightly higher tweeter with 50% MPX
In addition to these, the last two LEDs ( green and red ) are Custom Presets 1 & 2. ( See below )

To switch to a Preset, enter menu mode. To enter Menu Mode, press and hold button for > 1 second. Once LEDS flash,
[Menu] will be announced and the [Presets] menucan be selected. Once LEDs flash, 1 to 6 can be selected for preset.
*NOTE: If knobs 1,2 or 3 are adjusted across level preset setting for it's assigned value, ( See "KNOBS" below ) 
The knob will alter the EQ/MPX of the audio, but original Preset will remain for future selection. To avoid changing a 
Presets sound EQ, be sure not to adjust the knobs!
For example, you may select Preset #1, Classical, and perhaps Knob#1 is assigned to Midrange. If Knob#1 is adjusted
past the preset Midrange level, it will begin to adjust the Midrange audio up ( or down ) along with the knob.

[EQ Menu]
This menu allows advanced setting of custom EQ knob patterns, due to lack of knobs, and the 2 Custom EQ Presets.
[KNOBS]
Each knob can be programmed to be one of the EQ bands or the MPX control to suit your needs. Enter [Menu] mode
as described above. Select [EQ] and wait for LED flash. Select [knobs].
Slowly turn the knob to set it's program. The EQ/MPX/Presets will be announced. Do the same to set any other knobs
away from the last programmed setting. The Sub or bass tends to be a good choice for the lower knob(s) and
the midrange or tweeter for the upper(s). MPX can also be on a knob and can be useful for setting depth easily.
The last, found to the far right of knob, is Presets. This will allow instant loading of presets 1-6, like above, but on a
knob.
 [CUSTOM PRESETS]
The other two selections in the EQ Menu are presets 1 & 2 ( LED 2 & 3)
To set presets, enter [Menu] as described above, select [EQ], then one of the presets. Once LEDs flash, EQ
presets may be entered. All levels will update live, so listening to the type of music for which this preset will
be intended is a good idea. (i.e. Shortwave, TV, AM radio, MP3 player) If AutoSelect was on and locked on a channel,
it will remain locked during the menu mode indefinitely.

Each LED indicates an EQ band or MPX. As button is pressed, it's function is announced. Use the VOLUME
control ( top knob ) to adjust each level by ear. 
For example: Press button to LED 2 ( Bass) and adjust knob to adjust Bass. Press button to LED 3 (Midrange)
and adjust knob to adjust Midrange.
Each setting is stored to the selected Custom [Preset] as it is adjusted.

NOTE: To avoid accidentally setting it to the present  knob value without moving the knob, the adjustment doesn't 
actually start until the knob passes over the previous adjustment setting. For this reason it may be necessary to
turn knob enough to "capture" the setting and pull it down or up to the new value.

This mode can be used constantly if desired, but keep in mind channel select won't work, nor will Hour Timer.
To exit the Custom Preset menu, Press button and hold for > 1 second.
To activate the preset as a test, adjust the knobs differently, then Goto [Menu] then [Presets] 5 or 6.

[MPX]
The MPX system is effectively involved with a second audio processor the outputs to the rear speakers, and controls
"depth" of sound by mixing left and right channels in opposing phase. This level can be turned off to straight stereo
or turned on to 5 MPX levels, min to max. 
The best way to adjust this is to listen to music ( it doesn't work with mono tracks or shortwave/AM broadcasts ) and
adjust it up and down to suit. 
To adjust MPX, enter [Menu] as described above, then select [MPX] LED (# 5). Wait until LEDs flash, then use button 
to go from [OFF] to [ 5 ]. Once done, wait for a couple of seconds and chimes will indicate exit from Menu mode.
MPX can be assigned to a knob ( see above )

[Balance]
This seems a obsolete function but needs to be fine tuned depending on the acoustics of a space. This control only
 adjusts the front speakers Left and Right. The rear only varies with MPX settings.
Enter [Menu] as described above, then select [Balance]. Adjust VOLUME knob to set balance, then press button to
exit Balance mode.
Balance can be assigned to a knob ( see above ) if needed.

System Settings
System settings include disabling voice output, full system check, test mode.
To enter system settings mode, press and hold button for 3 seconds.
LED1 = turn off voice
LED2=turn on voice 
LED3 =System check: Checks 1420 chip, left and right, EQ functions, hour timer ( sets at 1 min), and LEDs
LED4=test mode: Specific Audio test routines
