 10. INPUT TV MODE PROGRAM NUMBER [1-999]

If value is “0”, TV should start in the last program number selected by user if in the previous control ATV / DTV 
is selected, this is the normal user TV behavior. If value is different from “0”, TV should starts in the specifi ed 
program number when it is switched on.

 11. INPUT MODE FIXED [VARIABLE  ↔ FIXED]

“FIXED” has been selected, any channels and input modes other than those selected at the start mode cannot 
be picked up.

12. RC PATH THROUGH [ON  ↔ OFF]     (Need additional Hardware)

When ON and RS-232 circuitry is really assembled , in pin #9 of RS-232 socket appears a feedback of the 
remote signal (3.3v logic type).

 13. HOTEL MODE [ON  ↔ OFF]

If ON has been selected the HOTEL MODE is activated.

14. RS-232C POWER ON [ENABLE  ↔ DISABLE]     (Need additional Hardware)

When this option is set to “ENABLE” it means that TV should be able to be switched on from standby mode 
through a RS232 command.

15. HDMI LEVEL POWER ON [ENABLE  ↔ DISABLE]     (Need additional Hardware)

Enabling this option, the polling of HDMI signal presence in a given HDMI input is being monitored. 
[TV in ON mode] If there isn’t HDMI signal present, after some seconds TV should go to standby
[TV in standby mode] If there is HDMI signal present, TV should switch on.

The Smartloader is a function implemented in the service software of SEE designed LE750 series intended to easily     
replicate the user settings of one TV into another. These settings include (but not restricted to): picture and audio, tun-
ing set-up, language and country selection, PIN, child locked programs… Factory adjustments are not copied as they 
are different for every TV.
The Smartloader makes possible the user data to be stored in a memory device connected to the USB terminal of the 
TV that is used as reference and later load those data into other TVs by using their respective USB terminal.

How it works.
In reference TV:

1. Insert a memory device in the USB slot.
2. Enter in service mode, select SmartLoader (Clone TV) menu.
3. Press “OK”.
4. Select “Save data” and press OK in the remote control.
5. Wait until “OK:0” is displayed, the fi le has been successfully created in the root directory of the memory device.
In case of error, an explanation message is shown. 

In TV to be cloned:

1. Insert a memory device with a fi le in it obtained following the above procedure.
2. Enter in service mode, select SmartLoader menu.
3. Select “Load data” and press OK button in the remote control.
4. After some seconds, “OK: 0” is displayed.  In case of error, an explanation message is shown.
5. Reboot the TV to load the new settings.

Very important: All the TVs must have the same software version and hardware.

The following information describes how to use RS-232 commands on the LE65x/75x series. We have also pro-
vided information on the adaptor cable required.

RS-232 cable 
The LE65x/75x series do not support RS232 connectivity with a standard D-Sub 9 pin connector and instead use a 
3.5mm jack input. To use this input for RS232 control it is necessary to adapt a connector cable. Please follow the 
instructions below on how to construct the cable. Be sure that you use a commercial available RS232 to TTL 3.3V 
level converter; nowadays there are a lot of USB-to-RS232 level converters on the market. You can fi nd some dif-
ferent models through FTDI company (www.ftdi.com).
