HOW TO SET UP YOUR NEW HITACHI COLOR TV
Before Installation (Geomagnetism Correction) 35TX20B Only
This TV has a super-large color picture tube. The effects of geomagnetism may cause an uneven (partially) colored
picture depending on the direction which the TV is facing. Adjust the TV as follows for best performance:
1.) Turn the power "OFF".
2.) Decide on the installation position and direction of the TV. Check the direction the TV is facing at this time.
3.) Set the DIRECTION and STRENGTH switches (on back of the TV) according to the direction of the screen as shown
in the table.

* If the Screen is facing a Northerly direction, Set to "N".
** If the screen is facin 9 a Southerly direction, Set to "S".
4.) After setting the switches, place the TV in the decided location.
5.) After relocating the TV, turn the power "ON" and check to make sure that the screen color (especially at the corners)
is even. Depending on the installation location (especially where it is susceptible to geomagnetism, for example,
in reinforced concrete building), picture color may be uneven even though you have set the switches as described
above. In this case, set the DIRECTION and STRENGTH switches to get the optimum picture.
6.) In certain areas, if the screen points North or South, color unevenness may be reduced when the STRENGTH
switch is set to STRONG rather than WEAK.
NOTE: If you move your TV, the DIRECTION and STRENGTH switches may need to be reset.
