Kenwood TM-251A Instruction Manual page 49

The frequency change is only temporary because it does
not alter the stored memory channel contents. You can
verify this by changing frequency while a memory
channel is selected, selecting a new channel with the
Tuning control, and then re-selecting the original channel
with the Tuning control. The original channel still
contains the originally stored frequency.
In the same way, changing settings of Tone/CTCSS,
Transmit Offset, etc. can-be done as in VFO mode but
the new settings will be temporary. Changing these
settings does not require Menu B, No. 56 to be ON.
Note: Frequency changes cannot be made when using Channel
Display.
MEMORY > VFO TRANSFERS
Transferring the contents of a memory channel or the
Call channel to the VFO can be useful if you wish to
search for other stations or a clear frequency near the
selected memory channel or Call channel frequency.
This is a quick operation that will be used frequently,
especially if you enjoy exploring the band.
1 Press [MR] to select Memory Recall, or microphone
[CALL] to select the Call channel.
2 Recall the desired memory channel using the Tuning
control.
e This step is not necessary if the Call channel was
selected.

3 Press [F], [VFO].
Note: Memory-VFO transfers cannot be done while in Full Dupi
mode.
The complete contents of the memory channel or
the Call channel are copied to the VFO for the
appropriate band. For example, data from a mem
channel containing a frequency of 144.900 MHz
would be transferred to the VFO for the 144 MHz
band.
The VFO for the band receiving the transfer is
selected after the transfer is completed.
A transmit frequency from a split memory chann
or split Call channel is not transferred to the VFO,
A memory channel that contains a frequency
outside the range of a VFO that has programmed
limits {page 33} will transfer to the VFO. Howey
as soon as the frequency is changed, the VFO
frequency will jump within the programmed range,
