CPU
Reset Procedures |
This is
a list of CPU resets for most ICOM radios. CPU reset returns the radio
to out-of-box condition: all memory channels are erased, all items in the
set mode returned to default values, and all VFOs cleared. CPU reset procedure
usually involves turning the radio off, pushing and holding specific
buttons, and then turning the radio back on while still holding down the
button combination. Some newer radios have a "partial reset" available,
as well as a full CPU reset. Partial reset will clear the VFOs and return
the set mode items to default, but it will not erase the memory channels.
