SELF DIAGNOSTIC FUNCTION

1. OUTLINE

• The units in this manual contain a self-diagnostic function.

• If an error occurs, the STANDBY lamp will automatically begin to flash. The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY lamp flash indicators is listed in the instruction manual for the user’s knowledge and reference.

• If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.

2. DIA GNOSTIC TEST INDICA TORS

• When an errors occurs, the STANDBY lamp will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the lamp will identify the first of the problem areas.

• Result for all of the following diagnostic items are displayed on screen. No error has occured if the screen displays a “0”.

Recording TV programs (continued)

Recording TV programs using the G-CODE

system

The G-CODE system allows you to simplify the task of programming your video TV to make recordings with the timer. Whenever you want to record a TV program, all you need to do is look up the program’s G-CODE number, a number assigned to each program published in the TV section of most newspapers and cable TV listings. Then, just enter the tape speed, sound mode, and the GCODE number of the program that you want and the video TV is automatically programmed to record that show.

Setting up the G-CODE system

Setting up your video TV involves coordinating the program number (the number you turn to on your video TV to watch a program) with the guide channel number (the number that’s assigned to that channel in your program guide). For a listing of the guide channel numbers, look in a program guide for your area that features G-CODE numbers.

Before you begin

• When the TV is in standby mode (the 1 indicator on the video TV

is lit in red), press ?/1 , PROGR +/– or a number button on the remote control.
