HF-90 Operation & Installation Guide
The HF-90 incorporates a direct entry Erase Function which
allows the operator to quickly and easily erase the memory
of the HF-90. This feature may be required if you wish to
ensure that channel/frequency information remains secure
.
To erase the memory of the HF-90, simply hold down the
CHAN (up) and CLAR (up) keys together for six seconds.
The display will appear as follows:-
Erase function
This display shows that the Erase Function is
in progress.
The display will show the word “ErASE” for twelve seconds
whilst the memory is being erased. Finally the HF-90 will
reset as though being turned on for the first time (refer to
Section 5.1 of this Guide).
Please note that this function will erase all channels in memory
except for one - the lowest channel. This is because the HF-90
requires a minimum of one channel programmed in memory at
all times.
