MODEL SERIES 34/36/39 INSTALLERS MENU (continued)
4-I STRT CHANNEL: Determines the channel that is se-
lected automatically each time the TV is turned on. Range
is 0-255. 0 is the Aux position and 255 is off. Use AD-
JUST to change the channel number. This feature is use-
ful for an in-house information channel, since the TV
would always tune the selected channel when the TV turns
on. When inactive the TV retains the channel when the
set was last used.
5-I CHAN LOCK: Defeats tuning operations. Changing
channels with the Channel Up/Down or keypad numbers
is impossible. This feature is ideal if a cable box (or simi-
lar) that must be always on the same channel or source is
used with the TV set. Range is 0-1. 0 is off and 1 is on.
In combination with the START CHANNEL, it can lock-on
a particular channel.
Note: When channel lock is active AUTO PROGRAM and
CH. ADD/DEL in the SETUP MENU are not active.
6-I GHOST CH: Either with or without signal present, the
channel number will stay on screen at all times, unless
captions are on. The number moves slightly to prevent
damage to the screen. Range is from 0 to 1. 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 informa-
tion channel, since the TV would always select the same
volume when it is turned on. The range of values are 0 -
63, 255. If 255 is set, the volume level is retained when
the set was last used.
8-I MIN VOLUME: This function determines the adjust-
ment of minimum volume level allowable with the keys
VOLUME Up/Down. In this way, for example, someone
cannot set the volume too low to hear. The range is from
0 to 63. When this item is set to 0, the sound level can
be adjusted down to zero. Change values with ADJUST
keys. The factory default is 0. It may be best to 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: This function determines the adjust-
ment of maximum volume level allowable with the keys
SR25-3828VD0171B
VOLUME Up/Down. In this way, for example, someone
cannot set the volume level high enough to disturb oth-
ers. The range is from 0 to 63. When this item is set to
63, the user has full adjustment capability. Change val-
ues with ADJUST keys. The factory default is 63. 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 above).

eration. Range is 0-1. Set to 1, sound cannot be muted.
