Outline:

Start up the unit as set to the TUNER function in the same procedure as the normal operation. Operations and
indication after startup are identical with the normal operations. However, what is different is that the frequencies
as shown in the table below are set to the tuner preset memory in advance.

Test mode operation:

(1) After entering the test mode, start up the unit with the tuner set to the preset No. 1 station, in the same manner
     as in the regular startup. When starting up, the following stations are preset which vary according to the
     destination.

(2) The operation is identical with the normal operation after startup.
(3) If the POWER key is pressed, irregular data is written in the RAM check data and the microcomputer is reset.
     With this operation, abnormal memory is detected during the reset process, and microcomputer settings are
     initialized.
