005 - CHAN LOCK (Channel Lock)
CHAN LOCK is ideal if the system must always be on
the same channel. Changing channels with Channel
Up/Down or keypad numbers is impossible. Channel Lock
is inactive if set to 0 (default).
Generally, this feature is used in connection with START
CHANNEL (Installer item 004) where the start channel
may, for example, be set to 3 or 4. If the start channel is 3,
then the 20LH1DC1 will remain locked on Channel 3.
007 - STRT VOLUME (Start Volume)
This function allows the Installer to determine the initial
volume level setting when the 20LH1DC1 is turned On.
This feature is useful for an in-house information
channel, since the 20LH1DC1 would always select that
volume level when it is turned On. The range of values
are 0 - 63, 255. If 255 is selected, the current volume
level will be retained in memory when the 20LH1DC1 is
turned Off; at turn On, the volume level will be
automatically set at the previous or last level.
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 —
change values with ADJ Left/Right arrow. The factory
default is 0, which provides the full range of volume
control, if item 009 MAX VOLUME is also set to 63. It
may be best to set the same value on every
20LH1DC1.
*Note: The minimum volume level cannot have a value setting higher
than the MAX VOLUME level (described below).
009 - MAX VOLUME (Maximum Volume)
This function determines the maximum volume level
allowable with the VOLUME (VOL) Up/Down controls. In
this way, for example, someone can not set the volume
level high enough to disturb others.
(Continued on next page)
*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).
Detailed Descriptions of Installer Menu Items
000 - INSTALLER SEQUENCE
Specifies entry sequence to the Installer Menu.
0 = 9876
1 = 4321
2 = 1478
3 = 3698
001 - POWER MANAGE (Power Management)
Determines hours of no activity before automatic
shutoff. The POWER MANAGE function is for saving
energy. If set to 0, Power Manage is Off. Settings range
from 0 - 7, with 1 - 7 representing the hours that the
TV will remain On, unless there has been activity from
either the control panel or remote control.
002 - AC ON (AC Power Switchable)
If set to 1, allows the 20LH1DC1 to turn On just by
applying AC power. Pressing the On button is not
necessary. This is desirable if the 20LH1DC1 is plugged
into a cable box or a power outlet controlled by a wall
switch. Use ADJ Left/Right arrow to choose 0 or 1
where 0 is the default is Off, and 1 is On.
*Note: If set to 1 (On), the 20LH1DC1 does not respond to
On/Off commands from either the remote or the display control
panel, and the SLEEP TIMER is also nonfunctional.
003 - BAND/AFC (Band/Automatic Frequency
Control)
Selects the tuning band. There are 4 possible settings
for this option:
0 = Broadcast
1 = CATV
2 = HRC
3 = IRC
If some channels were not found by Auto Program, select
the appropriate Band setting here and add the channels
using the Channel List option in the Channel Menu.
004 - STRT CHANNEL (Start Channel)
If active, this function allows you to determine the initial
channel number when the 20LH1DC1 is turned On.
This feature is useful for an in-house information
channel, since the 20LH1DC1 would always select that
channel when it is turned On. Setting this to 255
causes the last channel viewed when the 20LH1DC1
was turned Off, to be the tuned to channel when the
20LH1DC1 is turned On again.
255 = Last channel 1-125 = Ch X
0 = Aux
126 = Map to Channel 3. 127 = Map to Channel 4.
