Section 5.1
The display on the previous page will be shown for half a
second, immediately followed by another display showing
relevant software information. For example:-
This display shows: Option Level 1 - Release
1, Version 05.
The display showing software information will also time-out
after half a second. If you have an Advanced Model HF-90,
the display will then show your Selcall ID (4 digits) for one
second. At this point the HF-90 will revert to the default
channel/frequency display (refer to Section 5.8 of this
Guide). The channel/frequency shown will be the one
which was last in use.
Switching the HF-90 off
To switch the HF-90 off, move the ON/OFF switch upward
to the OFF position.
