3.1 PRECAUTIONS FOR ELECTRICAL ADJUSTMENTS 3.1.3 Signals required for adjustments NTSC and PAL color bar signals are required on "3.3 VIDEO SYSTEM ADJUTMENT". NTSC: 100% color bars (100, 0, 100, 0) (Without SETUP) 100% color bars (100, 7.5, 100, 7.5) (With SETUP) PAL: 100% color bars (100, 0, 100, 0) (PAL does not use SETUP.)

Electrical adjustments should be performed only when they are required, for example, during maintenance. Electrical adjustments that are possible only after mechanism adjustments should be performed after completing these. Before proceeding to perform electrical adjustments, be sure to warm up the unit for at least 10 minutes after turning it on. Use the 10:1 probe with the oscilloscope unless otherwise specified.

3.1.4 Notes for adjustments Since the AG-DV2500 is compatible with the recording and playback of the NTSC and PAL signals, it is required that both NTSC and PAL be adjusted. The NTSC and PAL signals use different Y signal V/S ratios and color levels. Be sure to use the specified signals for the adjustments. Both the NTSC and PAL signals use a variety of signals differing in the Y levels and color levels, etc. Also note that the NTSC signals include signals both with and without the Setup component. The AG-DV2500 is provided with input and output level adjustment capabilities only. If a signal of the specified level for color and setup is not available, read the following for the substitution. (1) Y level adjustments (Both of NTSC and PAL) If the available Y signal contains a white level of 100 IRE (PAL: 0.7 Vp-p), the signal can be used in the adjustment as described in the given procedure. If the input signal has the setup, adjust the luminance level from the pedestal to the white peak including the setup. (2) Setup level adjustment (NTSC only) The NTSC signal generator usually generates a signal with the Setup component. If it cannot be switched off, follow the alternative adjustment procedure for the signal with Setup, which is provided for each adjustment item. (3) Color level adjustments (Both of NTSC and PAL) The chroma level is variable depending on whether it is 75% or 100% and on whether the Setup component is present (NTSC only). As a result, a correct adjustment is not possible unless the specified signal is used. If the specified signal is not available, refer to the following. · Chroma level adjustment First measure the input signal what the signal type is (Refer to the table 3.1.4). Then apply the signal (composite or Y/C) to the AG-DV2500 and adjust the output signal level equal to the input type level. · Burst level adjustment The burst level is identical for all signals. There will be no problem if it can be adjusted to NTSC: 0.286 Vp-p (PAL: 0.3 Vp-p). There is no problem whether or not the Setup component is present (NTSC only).

Make sure of no cassette in the VTR. While holding the [REW] and [FF] buttons, press the [OPERATE] button to turn the unit on. When the unit is turned on, press and hold the [EJECT] button for about 2 seconds until the ADJUST MENU is displayed. Press the (FF) or (REW) button to select adjustment item. Press the [SET] (PAUSE) button so that the "*" marking blinks and, while observing the specified TP, the measuring instrument and others, press the (PLAY) button or (STOP) button to adjust the value to the specified value. (Pressing the [A.DUB] button simultaneously with the or button varies the adjustment value by 10 steps.)

Notes: · When the adjustment procedure requires a mode transition to PLAY, etc., use the accessory of wireless remote controller. · After completing all of the required settings, press [OPERATE] button to turn off the power. · To return to normal operating status, tur n the unit off then on again. If this is not performed, since the unit is turned on in the adjustment mode, pressing the MENU button displays an adjustment menu and it is not possible to display the normal operation menu.

When there are no specified signals, please refer to the "3.1.4 Notes for adjustments". · The monitor image may fluctuate horizontally during adjustments. This phenomenon occurs only in the adjustment mode and does not affect the adjustment results. · When an item is selected in the ADJUST MENU and INPUT SELECT SW sets to LINE or Y/C, the INPUT SELECT is switched automatically according to the selected item.
