In "Fixed" setting, the power-off by the power key of the unit is invalidated
and the image is kept being received. The power can be turned off by disconnecting the power supply. |
SHUT DOWN MODE |
[NORMAL / QUICK] |
MAXIMUM VOLUME |
[0 - 60 (60)] |
Sound volume can not be adjusted higher than the preset value.
When the sound volume is set lower than 59, only figures are
displayed and the sound volume bar is not displayed.
The maximum sound volume for ON-timer (Wake up timer) is limited
also to the preset value.
When the sound volume is set higher than the MAX setting by the
adjusting process, the sound volume control operation is prohibited
for turn-up and the sound volume should be turned down to MAX in this state. |
VOLUME FIXED |
[VARIABLE / FIXED / AC CTRL / AC/RC CTRL] |
FIXED: Fixed at the level adjusted for a fixed volume.
AC CTRL: Start-up at the level specified for a fixed volume at ACON.
AC/RC CTRL: Start-up at the level specified for a fixed volume at start.
The sound volume for the ON-timer (Wake up timer) is fixed also without
display of menu. Besides, the setting is made impossible. (Basically, the menu is not displayed.)
The following keys become invalid:
Sound volume Up/Down (VOL +/-) [for both remote control and the unit]
Mute (MUTE)
In the item "VOLUME" of adjustment process, the sound volume can be set
freely irrespective of this setting.
As for sound volume fixing and sound volume MAX level, the sound volume
fixing has priority. Once the sound volume has been changed by adjustment process,
it should be set back to the sound volume preset by sound volume fixing
level when the adjustment process ends. |
VOLUME FIXED LEVEL |
[0 - 60 (20)] |
The sound volume to be fixed by "Volume fixed" is determined.
Setting is valid only when "Volume fixed" is selected for "fixed". |

At the "No Respond" setting, the remote controller keys are disabled.
Its power key (reception/standby key) is disabled too.

All the other remote controller keys (power, volume up/down , channel up/down, light control
(brightness sensor), broadcast select) are inoperative.
At "No respond" setting, all the keys (including the power key) are not accepted.
Adjustment process, inspection process and hotel only keys are valid irrespective of setting. |

the current display stays on and no setting can be changed.
Even by initializing personal information, the hotel-mode settings are kept intact.
In this way, the AV positions, video and audio adjustment settings are not initialized. |

On the wide-screen models, an input selection is immediately made because the menu is not displayed.
At the "Limited" setting, some items cannot be displayed on screen. On the Japan-destined models,
the channel call "Message" alone cannot be displayed. (This is because the channel call message
may be confused with a message being sent from the hotel.)
On the North America-destined models, the OSD works the same as at the "No" setting.

Activating service mode
- Make sure the TV is switched off (not in standby)
- While keeping the 'INPUT' and 'MENU' buttons on top of the TV pressed, switch on the power, until 'Service Mode' and '---' appears.
- Enter the 3-digit entry code: 810
Note: According to the service manual to enter adjustment mode the following procedure should be followed (it did not work for me, though):

- While keeping the 'VOL-' and 'INPUT' buttons on top of the TV pressed, switch on the power, until the letter 'K' appears.
- Then hold the 'VOL-' and 'P-' buttons on top of the TV pressed, until multiple lines of blue characters appear.
When in service mode:
- Use Program up/down to go to the next line
- Use Cursor up/down to get to the next page
- Use Cursor Left/Right to change an item (+10/-10)
- Use Volume Up/Down to change an item (+1/-1)
- Use INPUT to select a different input
- Use RETURN to return to a present page
- Use Enter for executing a function
Here is a printout of the 16 pages of service mode from a KRL-32V.
Note that some settings are TV specific.
Also note that I have no idea what most settings do...., or what the effect will be (you might render your TV inoperable!).
