SECTION 3 TEST MODE

Fluorescent Indicator Tube Test Mode
All fluorescent segments are tested. When this test is activated, all segments turn on at the same time, then each segment turns on one after another. Procedure: 1. While depressing, the [A.F.D.] and the [DIMMER] buttons simultaneously, press the power `/1 button to turn on the main power. 2. All segments turn on at the same time, then each segment turns on press the [A.F.D.] button.
AM Channel Step 9 kHz/10 kHz Selection Mode (US and Canadian Models)
Either the 9 kHz step or 10 kHz step can be selected for the AM channel step. Procedure: 1. Set the FUNCTION to AM. Turn off the main power. 2. While depressing the [TUNING -] button or the [PRESET TUNING +] button, press the power `/1 button to turn on the main power. 3. Either the message AM 9kHz Step or AM 10kHz Step appears. Select the desired step.

Factory Set Mode

All preset contents are reset to the default setting. Procedure: 1. While depressing the [SET UP], and the [DIMMER] buttons simultaneously, press the power `/1 button to turn on the main power. The message Factry Set appears and the present contents are reset to the default values.

DSP Test Mode

It tests whether the DSP works correctly or not. When the DSP test is activated, the test data is output from the DSP (IC1401: CXD2712R) of the DIGITAL board and is written in the RAM (IC1402: IDT71V016S). When the test data is read from the RAM by the DSP, the data output must be equivalent to the original data. If they disagree, an error is triggered. Errors can be caused by the broken data line or defective soldering. Procedure: 1. While pressing the [MODE +] and [DIMMER] buttons, press the `/1 button to enter the DSP test mode. 2. The message DSP TEST MODE appears. When an error occurs, the message DSP2 ERROR is displayed. When there is no error, the message DSP2 NO ERROR appears and the 1 kHz signal is output to all channels. 3. Use the [MUTING] button, when selecting the SINE WAVE, THROUGH, or IMPLUSE mode.
