9) Factory Data Set/Erase < Fig16 > Factory Data Set/Erase Menu - Demo Stream Play It plays the demo stream stored at the HDD. - HDD Format It deletes all stored streams for the test and unnecessary files. Do not delete the demo stream at the time of the HDD format. - Test EEPROM set In order to reduce the test time, set channel map, favorite channel, and time information suitable for the test environment.
Page 38
10) Factory Set/Init < Fig17 > Factory Set/init - This mode performs the factory setting for HDD, EEPROM, Gemstar Board, and so on at the time of the final shipment. - The final shipment setting is as follows: 1) Delete the HDD area, but not the demo data 2) Set the EEPROM to the following values.
GEMSTAR UP-GRADE How to upgrade the Gemstar by G-Link * Note Upgrading the Gemstar by G-Link should have the boot ROM at the flash ROM of the Gemstar board. So, if there is no data at the flash ROM, this method is not possible, but possible for upgrading only. 1) Connect the G-Link cable to the G-Link connector of the Gemstar board.
Page 40
4) After the DOS window of the step 3 is popped up, the following window will be popped up. 5) After the window of the step 4, apply the power to the Gemstar board. Because the live power is applied at the SET state, if the Gemstar board is built in, disconnect the plug and plug it after 3 seconds, but if not, plug the Gemstar board to the set and connect the power plug.

7) The following message is displayed and upgrading continues. 8) When upgrading is completed, the following is displayed and all steps are finished. Upgrading takes about 6 minutes even it varies depending on the upgraded flash. 3-29...
