2 – 6

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 Preset No. 1 of table below. 

Set Preset Memory will be set as below table.

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.

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.)

If ASPM key is press again, ASPM operation will start from 2 untill 
5.

While scanning if 3 station memorized, Scanning will stop and 
operation 4 and 5 will take place.

Afterward, even if ASPM key input detect ASPM operation will not 
be execute. "__END__" displayed and operation canceled. 

Additional
Other then above, operation for ASPM are same with User 
operation. So, when 1st time scan with same PI code Station with 
most strong signal will be memory and will not be memory many 
time. For 2nd and more station with same frequency will not be 
memory.

But, if different station with same PI code (same PI with different 
frequency station), station one with most strong signal will be 
memory.

So, station that already memorized before scan will be ignore. 
Therefore, even station with same same PI code after 3 times ASPM 
scan, It is possible that, 3 station will be memorized in Signal Strong 
order. 

After Test Mode end only Tuner preset memory will be reset and set 
to default. Ohers Memory, no need to be initialize.
