Installer Menus
Installer Menu Items 4-I through 13-I: Detailed Descriptions
If some channels were not found by AUTO PROGRAM, select the
appropriate AFC setting here and add the channels using the
ADD/DEL option in the Setup Menu.
4-I. STRT CHANNEL (Start Channel)
When active, this function allows you to determine the initial
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. Setting this to 255
causes the last channel viewed when TV was turned off to be the
tuned to channel when the TV is turned on again.
The range of values is 0 - 255. Use (adjust) keys to choose num-
bers that determine the start channel.
5-I. CHAN LOCK (Channel Lock)
CHAN LOCK is ideal if a cable box (or similar) is the sole source
for programming—and the TV must always be on the same chan-
nel. Changing channels with Channel Up/Down or keypad numbers
is impossible. Channel Lock is inactive when set to 0 (default).
Generally, this feature is used in conjunction with START CHANNEL
(line 4-I.) where the start channel may, for example, be set to 3
or 4. If the start channel is 3 then the TV will remain on channel
3. NOTE: When CHANNEL LOCK is active and CHANNEL OVERIDE is
disabled, AUTO PROGRAM is not active.
6-I. GHOST CH (Ghost Channel)
When set to 1, the current channel number is displayed in the
upper right corner of the CRT. The number moves slightly to pre-
vent damage to the screen. The default is "0" or OFF.
NOTE: When captions are on, the "ghost channel" is not
displayed.
7-I. 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 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 TV is turned off; at TV turn on, vol-
ume level is automatically set to the previous or last level.
8-I. MIN VOLUME (Minimum Volume)
This function determines the minimum volume level allowable
with the VOLUME (VOL) Up/Down control. In this way, for exam-
ple, someone cannot set the volume too low to hear. The range is
from 0 to 63—change values with ADJUST. The factory default is
0, which provides full range of volume control. It may be best to
206-3853
set the same value on every TV.
NOTE: The minimum volume level cannot have a value setting
higher than in the MAX VOLUME level (described below).
9-I. 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 oth-
ers. The range is 0 to 63, with 63 as the default which gives the
user the full range of volume control. Change values with ADJUST
keys. It may be best to set the same value on every TV.
NOTE: The maximum volume level cannot have a value setting
lower than the MIN VOLUME level (described previously).
10-I. MUTE DISABLE
Enables or disables sound mute function. When set to 1, sound
cannot be muted. When set to 0, sound can be muted.
11 KEY DEFEAT (Keyboard Defeat)
When set to 1, it prevents the end user from accessing screen
menus on the front panel—MENU, SELECT, and ADJUST do not
function. When set to 0, those keys are functional. The menus can
always be accessed with MENU on the remote.
12-I. IR BANKS EN.
For direct access to a particular Channel Bank. When enabled,
installer can access a channel bank by inputting the IR code for
the bank.
13-I. SCAN MODE
Allows variation in setting the On/Off with Channel UP/DOWN.
You may opt for TV channels only; TV channels + Off/ON; TV chan-
nels + FM radio; TV channels + FM radio + Off/On with these set-
tings for Scan Mode:
