DEF

(Default)

–

above the button

Esc

– if you press it together with the

Ent

and release both buttons after that, the

letter “

d”

will appear to the right of the memory-cell number. This mark denotes a default cell that will be used by

default at a power on.

C A U T I O N

Before giving a

RCL

command, you have to stop any transmission.

RCL

(Recall)

–

above the button

– if you press it together with the

Ent

and release both buttons after that, the

contents of the current memory cell will be sent to the remote unit and it will become an active cell. Respectively, an
asterisk will appear to the left of the cell number.

STO

(Store)

–

above the button

– if you press it together with the

Ent

and release both buttons after that, the

current relay settings and the tuning frequency of the remote unit will be memorized in the currently displayed
memory cell. Respectively, an asterisk will appear to the left of the cell number (the cell content is equalized with the
remote unit status i.e. it has become active). In addition, on the bottom row appears the new frequency segment for
which the stored tuning will be valid.

You will see that after a command has been given, its inscription disappears from the screen – this will be a notice
that the command has been accepted and done. You can give an arbitrary commands queue while you are holding
the button

Ent,

as well as you can release it for each command.

c) Using the memory.

You can prepare AATU tunings for the frequencies that you use frequently and store them in different memory cells
(with numbers 1 to 99) using the command

Ent+STO

(Store). The button

AUTO TUNE

is active also while using the

memory and is to be used in the same manner as it was in the OPERATE function (see S.4-1). The button is not
accessible only when a command selection is being expected (

DEF, RCL

STO

combined with

Ent

Once you have memorized the tunings for all the frequencies of interest, you can retrieve them in an arbitrary order
from the memory using the command

Ent+RCL

(Recall), i.e. to get them active. The tunings do not disappear even

after you switch off the power supply, i.e. the tunings memory is nonvolatile.

After you have activated a memory tuning via an

Ent+RCL

(Recall) command, you may write its content in another

memory cell using the command

Ent+STO

(Store)

You will be able to rearrange the memory cells via “relocating”

them in new cells (without a retune) and then using the “vacated” cells to store new tunings there.

N O T E

Using too old tunings can exhibit high SWR (if the conditions at the antenna have
changed significantly since the day the tunings have been stored). Should this
happen, we recommend that you refresh these tunings using the

AUTO TUNE

procedure and then store new tunings via the

Ent+STO

(Store) command.

Once a memory cell gets activate, you can abandon the Memory sub-function temporarily by pressing the button

Esc

until you reach the main menu. Then, the remote unit tuning is not being changed since the current tuning status is
being considered being operative. In this situation, you can use either function

BYPASS, STATUS

SWR-CHK

(for

instance checking the ATU resource in use or the present SWR of an old tuning). If you have not made any

AUTO

TUNE

meanwhile, at returning to the Memory sub-function you will have the same tuning status as it has been before

you left it (even if you have used the

BYPASS

function).

Should you need changing the default power-on memory cell, select the new cell via the buttons

and then use
