Recalling data
To recall data, press the soft key for the type of recall required, e.g.
[Carrier Recall]
and select the
location by means of the key pad. The [
×
] and [
Ø
] keys can be used to recall the next locations.
Pressing
[Return]
recalls the location last specified on the numerical key pad.
Stores can be incremented or decremented externally by means of the SWEEP TRIGGER socket
(see 'External trigger' above).
The settings for the sequential calling tones are recalled via the calling tones menu in
UTILITIES, see Fig. 3-69. These stores can be erased from the Store Erase Menu.
Inhibit ON/OFF
When recalling full or partial stores it is sometimes useful for the existing carrier frequency setting
to remain and not be replaced by the stored setting. The Inhibit Carrier Recall facility offers this
capability. To prevent the current carrier frequency from being replaced use the
[Inhibit
ON/OFF]
key to set the
Inhibit Carrier Recall
annunciator to
ON
.
To allow the carrier frequency setting to be overwritten use the
[Inhibit ON/OFF]
key to set the
Inhibit Carrier Recall
annunciator to
OFF.
Memory stepping facility
The [Sig Gen] key has a toggle action in that pressing the key a second time displays the
Memory
Stepping
menu shown in Fig. 3-83. This facility enables the memory to be stepped up and down
from a start location (selected using the
Memory Recall Menu
), whilst displaying the settings for
that memory.

Fig. 3-83 Memory stepping menu
Pressing
[Memory Up]
or
[Memory Down]
respectively increments or decrements the memory
location. With each step the settings stored in the location are displayed together with, at the top
left of screen, the memory type and location e.g.
Full 48
. Incrementing and decrementing can also
be done externally by means of the SWEEP TRIGGER socket (see 'External trigger' above).
Pressing
[Memory Return]
at any time returns to the start location.
When a limit is reached, e.g. for Full Recall locations 0 and 49, a further step will reset to the start
location. But note that if the start location coincides with a limit, trying to step past that limit will
cause the limit and start locations (in this case the same numbered locations) to be alternately
displayed. To make the user aware of this situation, the message
At Top Limit
or
At Bottom Limit
is displayed at the top centre of screen.
