To RESET the CPU (and wipe out memory), hold the LIGHT button AND the
FUNCTION button while CPU is on, then turn it off, wait a second, and
turn it back on. Continue holding the buttons while all the LCD segments
display until "46.01" shows (about 1-2 seconds). This puts the radio
into 5/10/15/20/25 khz step mode. Its starts in 15 khz steps and other
steps in the list may be chosen. I wish 30 khz were in the list.
The instructions for the IC-2GE are similar except that you hold down
LIGHT and the WR button on top right next to the power switch. The
IC-2GAT also performs this same reset, and also enters the 12.5/25 khz
step mode. The step starts at 25 khz. When it is set to 12.5 (the only
other choice until you reset the CPU the first way) you can dial up
frequencies like 146.0125 which shows like "46.0125" where the "25"
are BOTH smaller digits. The "5" never shows in the "American mode".
The display goes to "46.01" in the "American mode" and to "46.00" in
the European mode.
Another curiosity is that when I RESET my CPU, I did so while it was
tuned to 162.55 (weather). When I turned the power back on, EVERY segment
was displayed, but the radio was actually receiving 162.55 anyway. Then
when the reset finally took effect, the display went to "46.01" and
the weather signal was lost. I also notice that sometimes, the "U" for
synthesizer unlock (in the 10's position of the memory number) shows up
just at the moment the "46.01" or "46.00" does, then ends in a second.
I guess the sythesizer is being reset as well.
