SERVICE MENU (continued)
SR23 - 923-03509 2-2 CS - SERVICE MENUS
Note: The minimum volume level cannot have a value setting
higher than in the MAX VOLUME level (described
below).
08 Max Volume: Determines the maximum volume level
allowable with the VOLUME (VOL) Up/Down Control.
In this way, for example, someone cannot set the vol-
ume level high enough to disturb others. The factory
default is 63, which provides full range of volume con-
trol. It may be best to set the same value on every TV.
Note: The maximum volume level cannot have a value setting
lower than in the MIN VOLUME level (described above).
09 AC on: Allows the TV to turn ON just by applying AC
power. Pressing the ON button is not necessary. This
is desirable when the TV is plugged into a cable box
or a power outlet controlled by a wall switch. Use ad-
just to select 0 or 1, where 0 is OFF and 1 is ON.
Note: When set to 1 (ON), the TV does not respond to ON/
OFF commands from either the remote or the control
panel, and the SLEEP TIMER is also nonfunctional.
10 Key Defeat: When set to 1, it prevents the end user
from accessing screen menus on the front panel keys,
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.
11 Strt Ch: When active, this function allows you to set
the initial volume level setting and channel number
when the TV is turned ON. This feature is useful for an
in-house information channel, since the TV would al-
ways select that channel when it is turned on. When
inactive, the volume level and channel retain the set-
tings when the set was last used.
The range of values is 0-255. Use the ADJUST keys to
choose. With number 255 the feature is inactive. Other
numbers determine the start channel. Set the volume
level as desired before exiting the service menu. 0 is
the “AUX” channel.
12 Strt Vol: When active, this fuction allows you to de-
termine the initial volume level setting when the TV is
turned on. This feature is useful for an in-house infor-
mation volume, since the TV would always select that
volume when is turned on. When inactive, the volume
level retain the settings when the set was last used.
13 Not Used
14 Chan Lock: When set to 1 the CHAN LOCK is ideal if a
cable box (or similar) is the sole source for program-
ming and the TV must always be on the same channel.
Changing channels with the Channel Up/Down or key-
pad numbers is impossible. Channel Lock is inactive
when set to 0 (default).
Generally, this feature is used in connection with START
CHAN/VOL 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.
15 Ghost Ch: When set to 1, the current channel number
is displayed in the upper right corner of the CRT. The
number moves slightly to prevent damage to the
screen. The default is “0” or OFF. When captions are
on, the “ghost” channel is not displayed.
16 Not Used
17 Text Mode: Determines whether TEXT 1 and TEXT 2
decoding is enabled when CAPTIONS are turned on (ei-
ther from the Setup Menu or directly with CC on re-
mote). When set to 1, only Caption 1, 2, 3, and 4 are
enabled. When set to 2, Caption 1, 2, 3, and 4 and
Text 1, 2, 3, and 4 are enabled.
18 Sleep Timer: When set to 1, a end-user may set the
SLEEP TIMER feature (but no message is displayed prior
to turnoff). When set to 0, the sleep timer is not avail-
able.
19 Alarm: Gives you the option of making the alarm func-
tion available to the end-user. Set to 1, alarm func-
tion is available. Set to 0 to withhold this function.

select channels with either Channel Up/Down or by

nels that are entered for scanning may be selected.
