Solution

 

1.  The  power  indicator  (green  LED) 

on front panel of the tuner doesn't

a.  Check  that  the  power  plug  is  properly  inserted  into  a  functioning 

power outlet. 

b.  Press the "POWER" button on the front panel to see if the green light 

(power indicator) is on.

the desired tuner output connector and your TV set 

c.  Be sure to perform a channel scan before you watch the TV program. 

3.  Poor picture quality 

a.  Confirm that the antenna is pointing in the correct direction. Perform 

an  "Auto  Scan"  to  check  the  signal  RF  Level  when  aligning  the 
antenna. 

b.  If  you  use  any  kind  of  amplifier  to  boost  the  signal  level,  check  to 

verify that it is operating properly. 

c.  Try the solutions noted in item (2) above  

4.  No audio
