SHARP AN-PR1000H 

Test Mode
1. Entering the test mode
In the AC OFF state, hold down the “FUNCTION” key and press the POWER key. Then switch on AC to enter the test mode route state.
* Be sure to follow the above procedure to enter the test mode.
2. Exiting the test mode
In the test mode route state, press the POWER key to turn off the system and exit the test mode.

EEPROM Mode
When replacing EEPROM IC, necessary data are not recorded inside; “Protect area read error” (“ERR 80”) occurs. To avoid this state, write the data into the corresponding device.
1. Enter the test mode and check set data values of each address according to the EEPROM set data table on the right. If necessary, change the set data values.

2. Exiting the EEPROM mode from the address value display state.
(Press the POWER key once in the address value display state.) (The product enters the test mode route state.)
3. Exiting the test mode
(Press the POWER key once in the test mode route state.) (Then the data are written into EEPROM. After the write operation, the product enters the standby state.)

4. After checking that the product enters the standby state, stop power supply to the product.

Quick Volume Change Mode
Purpose
The purpose of this mode is inspection time shortening in the production.
This mode is the same as the USER MODE except for the volume operation.
Volume operation in this mode becomes a change in a step only to the necessary position in inspection process.
The specification of operation
Main volume operation at QUICK VOL CHANGE MODE

NOTES:
(1) About operation specification of "VOL +/– key".
(2) A difference from this mode and the user mode is only a possible volume steps and initial value after the mode start.

Tuner Test Mode
Outline
This Test Mode control are same with Normal Power-ON, only
Power-ON in TUNER function.
After Power-ON the operation and display are same but the TUNER preset already memory as table below.
TEST Mode Operation
Set will Power-ON same process like user Power-ON, but direct to
TUNER Function

Key operation after Power ON are same with User Power-ON.
* When Test Mode end, Tuner Preset Memory will be initialize. Others Memory initialize is not neccesry.

ASPM Test Mode (For EU Destination)
Outline
At Tuner RDS ASPM operation need to be confirm for EU(H) model only.
Power-ON in TUNER function, and scanning frequency from
105.00MHz - 108.00MHz. And RDS station Preset Memory maximum 3 station.

TEST Mode Operation
Power ON in TUNER Function 106.50MHz FM Stereo Band. At
same time Only Preset No. ch1 - ch3 leave blank and all ch4 - ch40 memory at 87.50MHz FM Stereo Band. With the press of ASPM key, ASPM operation will start at 105.00MHz frequency. If RDS station received Preset will memory from ch1. (There is no need to memory PS name in ASPM Test Mode. If preset change during Test Mode Frequency will be display first)
Scan will stop after reach frequency 108.00MHz, and return to frequency 106.50MHz FM Stereo.
To confirm Memory content display will show Preset Number and frequency for ch1until ch3. After display are confirmed frequency will return to 106.50MHz FM STEREO. (Display method same with Tuner display during Normal POWER ON.)

Failure detection
1. SYS-PROTECT detection: To detect failure of the power supply circuit (except the 1.8 V power supply circuit).
2. B_CHECK detection: To check timing at power ON/OFF and detect over voltage and reduced voltage of the primary AC power after the power is turned on.

3. AVCK detection: To detect failure of the 1.8 V power supply circuit (AVCK1 and AVCK2).
4. AMP_SW_PROT detection: To detect failure in the subwoofer AMP.
