Installer Menu (Cont.)
003 - BAND/AFC (Band/Automatic Frequency Control)
Selects the RF band used by the NTSC tuner:
0 = Broadcast 1 = Cable (default)
2 = HRC 3 = IRC
Determine the RF band used by the RF distribution system, and
then select the appropriate value for this item before tuning
channels or running Auto Tuning (Channel Search). See also item
102 ATSC BAND.
004 - STRT CHANNEL (Start Channel)
If active, this function allows you to determine the initial Major
Start Channel number when the TV is turned ON. This feature is
useful for an in-house information channel, since the TV would
always select that channel when it is turned ON. If set to 255,
the last channel tuned before the TV was turned OFF will be the
channel tuned when the TV is turned ON again.
0 = Aux
1 125 = Major CH #
–
126 = Map to Major CH 3
For a digital (ATSC) Start Channel, always remember to set item
104 to the Minor Start Channel number. If setting this item to 0
(Aux), make sure to also set item 046 STRT AUX SRCE to the
appropriate value.
Note: 126 and 127 are mapped only in SONIFI PPV Mode.
005 - CHAN LOCK (Channel Lock)
Channel Lock is ideal if the system must always be on the same
channel. If set to 1, Channel Lock is enabled and it is not possible
to change channels. If set to 0 (default) Channel Lock is disabled.
Generally, this feature is used in connection with item 004 STRT
CHANNEL where the Start Channel may, for example, be set to
3 or 4. If the Start Channel is 3, then the TV will remain locked on
channel 3.
NOTE: For items 007, 008, and 009
For legacy reasons, the scale used is 0 – 63. The PTC software
will translate this to the 0 – 100 scale used by the TV.
To translate a TV volume level to the Installer Menu value, use
the following formula:
Installer Value = TV Value x 63
100
Enter only the whole number (disregard fractions).
007 - STRT VOLUME (Start Volume)
This function allows the Installer to determine the initial volume
level setting when the TV is turned ON. This feature is useful for
an in-house information channel, since the TV will always select
that volume level when it is turned ON. The range of values is 0
to 63, 255. If set to 255, the last volume level before the TV was
turned OFF will be the current volume level when the TV is turned
ON again.
40
127 = Map to Major CH 4
255 = Last Channel
Note: The factory default volume level (i.e., when AC power is
initially applied) for these TV models is 20. In addition, if AC power
is removed/disconnected and then reapplied to the TV while this
item is set to 255, the TV volume level will revert to 20 when the
TV is turned ON again.
008 - MIN VOLUME (Minimum Volume)
This function determines the minimum volume level allowable
with the Volume (VOL) Up/Down control. In this way, for example,
someone cannot set the volume too low to hear. The value range
is from 0 to 63. The factory default is 0, which provides the full
range of volume control, if item 009 MAX VOLUME is set to 63. It
is recommended to set the same value on every TV.
Note: The minimum volume level cannot have a value setting
higher than the maximum volume level (described below).
009 - MAX VOLUME (Maximum Volume)
This function determines the maximum volume level allowable
with the Volume (VOL) Up/Down control. In this way, for example,
someone cannot set the volume level high enough to disturb others.
The value range is 0 to 63, with 63 as the default, which gives the
user the full range of volume control, if item 008 MIN VOLUME is
set to 0. It is recommended to set the same value on every TV.
Note: The maximum volume level cannot have a value setting
lower than the minimum volume level (described above).
010 - MUTE DISABLE
Enables or disables sound mute function. If set to 1, sound cannot
be muted. If set to 0, sound can be muted.
011 - KEY DEFEAT
If set to 1, Key Defeat is enabled, which means that end users
cannot access or navigate within the on-screen menu(s) from the
display panel; i.e., joystick button menu navigation functions will
not be available. Set to 0 to disable Key Defeat. Note that all IR
features remain functional regardless of this setting; users can
always access the menus by pressing MENU on the remote.
Note: This item is only applicable for 24/28LT572M TVs.
012 - IR BANKS EN. (IR Banks Enable)
When enabled, you can direct access a particular channel bank
by inputting the discrete IR code for that bank.
Note: This item is not available in the Installer Menu when item
027 HOSPITAL MODE is set to 0.
013 - SCAN MODE
If set to 1 (default), the TV can be turned ON with Channel
Up/Down key presses. Also, the TV will turn OFF when Channel
Up/Down is used to tune above or below the Channel Map pivot
point. By default, the Channel Map pivot point is between the
highest and lowest channel in the Channel Map (also see item
014 STRT CH IN SM). Set to 0 to disable.
Note: This item is only applicable when the TV is in PTC-CTV
Mode or FTG Mode via CPU.
