TP CHASSIS / TELEVISION

72 September 2011

TV  MODE  tab  contains  "Factory"  and  "Customer"  options.  It  is  used  to  perform
factory controls and settings more efficiently and faster.  On the TVs delivered to the
customer, this setting is absolutely selected as "Customer." Otherwise, it will lead to
customer  complaints  such  as  "TV  automatically  turns  on  after  power  failures"  or
"different functions operate from the remote control".

HDCP  VERIFY:  It  must  be  checked  if  HDCP  key  is  loaded  or  not  during  factory
controls. HDCP key stands for ““High Bandwidth Content Protection Key”.  This key
is used to prevent copying of data on digital sources such as DVD or blue-ray. With
HDCP,  video  data  is  transmitted  from  the  source  to  the  receiver  as  encrypted.
Therefore, to watch HDCP encrypted DVDs or blue-ray, HDCP key should have been
loaded on TV. On the products with HDCP installed, SUCCESS message is included.

DEBUG MODE is the feature, which is used to track software modifications made on
TV during R&D stage. This setting must be "Off" on TVs delivered to the customer.

PLUG  PLAY  (Demo  Mode):  A  navigation  key  is  pressed  after  having  completed  all
settings and checks in the factory. Later, "Please wait" message appears; and when
you see the message "DONE", the device should be unplugged and plugged again.
With this process,  television  will be set to  its initial  values before delivery. It will be
proper  to  set  Plug&Play  tab  after  servicing.  After  pressing  right  key  on  the  tab,
EEPROMs  will  be  loaded  with  factory  defaults.  TV  can  be  shipped  to  the  customer
after this setting. Please note that any warning is not displayed or you do not have to
exit the menu while Plug&Play is getting activated. You should be careful not to take
the device into Plug&Play mode by mistake.

ATS  (Auto  Service  Numbering)  feature  ensures  that  the  channels  are  arranged  in
order  after  automatic  search.  However,  there  should  be  broadcasting  support  to
number the channels. It is active when “On” is selected. “On” should be selected in
TP-chassis products.

SRS (Virtual multi-channel sound system) tab turns on and off SRS Tru-Surround HD
feature.  SRS  Tru-Surround  HD  creates  a  sound  experience  surrounding  the  user
similar  to  5+1  sound  systems,  thanks  to  multi-channel  audio  by  using  two
loudspeakers  produced  by  SRS  company.  SRS  is  an  optional  feature  that  can  be
selected upon the customer’s request.

BLUE  BACK  enables  us  to  determine  background  when  there  is  no  picture  on  the
screen. When "On" is selected, background will be blue; and when "Off" is selected
background  will  be  black  or  snowing.  “On”  should  be  selected  in  GRUNDIG  brand
products and “Off” in other products.

HOTEL tab should be set to "On" with the products for which Basic  Hotel TV feature
is  desired;  and  it  should  be  set  to  "Off"  in  other  products.  When  the  hotel  model  is
"On",  certain  features  designed  for  the  hotel  use  are  activated;  the  user  cannot
change  the  channels  set  by  the  service,  for  example,  or  the  volume  cannot  be
increased more than a certain level.
