Detailed Descriptions of Installer Menu Items.

0-I. INSTALLER SEQUENCE

Gives access to Installer Menu depending on the code

selected.

0 = 9876 1 = 4321

2 = 1478 3 = 3698

1-I. POWER MANAGE (Power Management)

Determines hours of no activity before automatic shutoff.

SECTION 2

The POWER MANAGE function is for saving energy. When

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 con-

trol panel or remote control.

2-I. AC ON (AC Power Switchable)

Allows the TV to turn ON just by applying AC power. Press-

ing 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 ADJUST to select 0 or 1,

where 0 is the default 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.

3-I. BAND/AFC (Band/Automatic Frequency Control)

There are 8 possible settings for this option:

0 = Broadcast Fixed 4 = Broadcast AFC

5 = CATV Fixed 1 = CATV AFC

6 = HRC Fixed 2 = HRC AFC

7 = ICC Fixed 3 = ICC AFC

Channels are accessed faster when fixed modes are used.

The AFC (search modes) should only be used when some

channels are not on nominal frequencies.

NOTE: BAND is automatically set by AUTO PROGRAM.

If some channels were not found by AUTO PROGRAM, se-

lect the appropriate AFC setting here and add the chan-

nels 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 chan-

nel when the TV is turned on again.

The range of values is 0 - 255. Use (adjust) keys to choose

numbers 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 channel. 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 ex-

ample, be set to 3 or 4. If the start channel is 3 then the

1 2 ... 14 15 16 17 18 19 20 21 22 23 24 ... 47 48
