Other cautions · TOC IL is not executed in the test mode. · As for button operations other than those shown above, only the sound volume operation (with JOG) is accepted. 3. Tuner Test Mode (TEST 2) 1. Outline of tuner (radio) test mode The tuner test mode is intended to store the adjustment and measurement frequencies in the preset memory CH without frequency setting by adjusting personnel when the tuner section is adjusted in the production line. 2. Details of tuner test mode When the power is turned on by using the "POWER" button while the "Volume/JOG Dial Selector" and "Volume Select" buttons are held down in POWER OFF state, the frequency for adjustment and measurement of destination specified by the AREA terminal is preset and stored in the preset memory CH. However, Ordinary 1 and Ordinary 2 are set to the designation (destination selected by SPAN switching operation) set when the test mode is set. (As for frequencies to be preset and stored for each destination, refer to item 3.) The tuner test mode is started from preset No.1. The operations of test mode are identical with the ordinary operations of TUNER function. However, FUNCTION switching is invalid. Since it is necessary to discard the content of preset memory when the tuner test mode is ended, "0000" or "1111" bits are written in the memory to be checked in case of memory check (in case of initial setting) so that memory abnormality is detected in case of initial setting so as to ensure memory initialization. When the tuner test mode is turned on, the following indication lights for one second.
· The TUNER TEST2 mode is set as a result of Volume Select + POWER. -> IF AC is set to OFF in the TEST2 mode, the initial state is restored.
When POWER is set to OFF, the memory of TEST2 mode is protected. When the power is turned on again, the ordinary operation is enabled while the data is stored in the memory (besides TUNER).
If AC OFF state is maintained in this state for about 1/2 day, start is executed in the initial state. · To clear the whole memory, insert the AC cord, holding down MEMORY + PLAY.
