When a charged main battery is connected, memory is held up by it, and the
HUB is automatically disconnected to extend its life. The HUB should be
replaced each year.
If the HUB is removed or goes dead without a main battery connected, the radio
will require type-1 initialization and cannot be operated in CT. The password will
default to H2445830 if type-1 initialization is lost.
