CONTROL FUNCTIONS 

 
The MD 109 is equipped with an audio sensing circuit, which protects the unit 
from any unsafe operating conditions. If an unsafe operating situation should 
occur the unit will automatically be muted, and if the fault lasts more than two 
minutes a light will flash on the circuit board and the unit will not come back on 
until serviced 
 
The following functions are displayed clearly on the touch screen. Each funtion’s 
utility is explained below. 
 
1.

 

POWER

: Controls the power to all display functions. When in the standby 

condition the screen will display the Magnum Dynalab logo and the word power 
in the lower left hand corner.  

 
2.

 

MUTE

: Controls the elimination of inter-station noise. It is recommended that, 

when receiving marginal signals, the mute be set to off. This will eliminate 
intermittent loss of signals that fall below a specific signal value. The word 
“mute” will appear on the screen when activated. 

 
3.

 

STEREO

: Controls whether the tuner is operating in Stereo or Mono mode. 

The word “stereo” will be displayed in the right hand corner of the screen when 
you are in the stereo mode. 

 
4.

 

BAND

: This switch controls the IF (intermediate frequency) selectivity. The 

setting you are on will be displayed in the top right hand corner of the screen. 
The different settings are described below. 

 

a.

 

Super Narrow: Controls the IF super narrow setting. This setting should 
only be used in extreme reception conditions of adjacent channel 
problems. The words super narrow will be displayed on the screen when 
activated with the Band switch. 

b.

 

Narrow: This setting combines excellent frequency response with high 
adjacent channel selectivity. The word narrow will be displayed on the 
screen when activated by the Band switch. 

c.

 

Wide: Controls the ultra wide IF setting and offers the best frequency 
response.  The word wide will be displayed on the screen when activated 
by the Band Switch. 

 
5.

 

DIM

:  When activated, the brightness of the screen will be reduced by 50 %; 

this will extend the life of the screen. The screen will automatically dim after 2 
minutes of inactivity.
