7 Test mode operations
- When the product enters the test mode, two center LEDs will
flash .
- All operation buttons, except for the [REC] and [REVERSE
MODE] Buttons, provide normal operations in the mode.
- When all LEDs remain extinguished, shift the TC/MD signal
selector to the MD side inside the CT-R5.
(1) LED check
Each time the [REVERSE MODE] button is pushed, the LED
operation changes as follows:
Normal display = All LEDs ON = All LEDs OFF = Leaf
+
(2) Leaf SW check
When the leaf switches are depressed, their corresponding
LEDs light up as follows:
Leaf switch LED
REV REC SW .............................. REC LED
FEW REC SW .............................. FWD LED
CrO
SW ........................................ DOLBY LED
2
HALF SW ...................................... REV LED
(3) Auto REC/PLAY operation mode
Push the [REC] button. The auto REC/PLAY operation mode
starts:
1. Sets the function of tuner amp to AUX.
2. One second later, starts 5-second FWD recording.
3. Performs REV recording for 5 seconds.
4. Shifts the function to TAPE, then performs FWD play for
5 seconds.
5. Stops operations.
* When the [REC] button is pushed once again, the above
operations are repeated.
** After the auto REC/PLAY operation is completed, when the
[REV] button is pushed, CT-R5 performs REV play for 5
seconds and stops operations.
7 How to cancel the test mode
