The operations of test mode are identical with the ordinary operations of TUNER function. FUNCTION switching is invalid.
It is necessary to discard the content of preset memory when the tuner test mode is ended; be sure to write "0000" or "1111"
bits in the memory to be checked for judging memory error at initial setting and to initialize memory.
When the tuner test mode is obtained, the following display lights for one second.
• The TUNER TEST2 mode is obtained with >> + MEMORY + ON/STAND-BY. ->Turn off AC in the TEST2 mode to restore
the initial state.
Turn off POWER to protect the memory of TEST2 mode.
Turn off POWER again to obtain the ordinary operation while the data is stored in the memory (besides
TUNER).
Turn off POWER again to obtain the ordinary operation while the data is stored in the memory (besides
TUNER).
If AC OFF state is maintained in this state for about 1/2 day, start is executed in the initial state.
• To clear the whole memory, insert the AC cord, pressing MEMORY + CD PLAY.
