Over the weekend, I took some time to experiment with my Kenwood mobile
rigs and was quite surprised at what I found.
OTHER TM-741 UNDOCUMENTED FEATURES
DISPLAY TEST
Hold down F and MHZ while turning on power. This activates the display
test mode where all segments and indicators are lit. Note the "ACC"
indicator at the lower right. ACC is not defined in the manual, however
I saw it come on once one night after I started the car with the radio
turned on. The display lit up ACC and the UHF frequency display showed
some sort of HEX code (a ROM checksum maybe?).
STRANGE TEST
(WARNING: YOU MAY LOSE SOME SAVED MEMORY DATA)
Hold down the F and MR keys while turning on power. The radio plays
a wild sequence of tones and the displays go all crazy for several
seconds. When it's done, everything seems normal except that the
memory contents are reshuffled and some memories are duplicated.
I can only speculate that this might be some sort of factory memory
test...
