<p>PURPOSE:To facilitate slow subtracking adjustment by changing a tracking value in the slow mode and storing the tracking value to a memory when a mode setting key not giving effect onto the slow mode is operated for a prescribed period. CONSTITUTION:When the mode is set to the slow mode and it is discriminated that an UP/DOWN key 18 is depressed, a digital tracking value is changed and whether or not a REC key 21 is depressed is discriminated. When the key is depressed, whether or not a fluorescent display tube 10 is in the tracking state display period is discriminated. Then a prescribed display is indicated to a display section of the fluorescent display tube 10 for 3 seconds after the depression of the UP/DOWN key 18 is released and when the REC key 21 is depressed for the display period, the set subtracking value is stored in an EEPROM 19 and the indication of representing memory storage is given. The value stored in the memory indicates a slow sub tracking center after the adjustment.</p> |
