1. Outline of tuner (radio) Test Mode
The tuner Test Mode is intended to store adjustment/measurement frequency in the preset memory CH without frequency
adjustment by the adjusting personnel when the tuner is adjusted in the production line.
adjustment by the adjusting personnel when the tuner is adjusted in the production line.
2. Details of tuner Test Mode
When power is turned on with the POWER key while the MEMORY/SET key and BAND key are held down together in
POWER OFF state, the frequency for adjustment/measurement of specific destination specified by the AREA terminal is
preset-stored in the preset memory CH (the frequency to be preset-stored for specific destination is explained in the Item
C). When the tuner Test Mode is started up, it is started with FM. FM is FM STEREO only.
When the REW key is pressed while the preset memory CH is 1CH, the highest CH is found as in case of regular mode. When
the FF key is pressed while the preset memory CH is highest CH, 1CH is found.
The RADIO (TUNER) BAND key (or TUNER/BAND key on the remote controller) is valid.
As in case of regular mode, selection of band, FM MONO/STEREO mode is enabled by pressing the RADIO (TUNER) BAND
(or TUNER/BAND ) key.
Exiting the tuner Test Mode, When the destruction data is stored in the memory in the tuner Test Mode, AC supply is
interrupted in the Test Mode and the AC supply is recovered, all the memory is cleared with the destruction data in case of
start-up.
(Countermeasures so that the Test Mode memory does not remain when AC supply is restored after power supply failure
occurred once in the Test Mode.) The memory is not cleared when AC supply is turned off after POWER OFF.
FUNCTIONkey is not accepted in the tuner test mode. In case of exit from the tuner Test Mode through the backup mode
upon occurrence of power failure the frequency data stored in the preset memory for adjustment/measurement is erased.
(As a result the preset memory CH becomes empty.)
