G.3.4 NVS/Sony Problems

• Invalid Num - If the message `Invalid Num' appears on the display monitor, the nvs box is not in sync with the Sony laser disk. To correct this situation begin with a blank frame check (see above hardware procedure) and follow that with software procedure shown above.

• One common problem is to forget to attach the RS-232 cable. This is sometimes switched to ISASS3 to control the recorder during playback to record with the VCR).

• How to toggle the format frame/time format: depress the frame/time button located on the lower-left side of the console number keypad-where frame # is a simple number and time has the format of mm:ss:ff.
