4. To scan only the memory channels, press the
MR switch, and then either the UP or DOWN
switch. The scanner will search all ten
memory channels. Press the PTT switch
on the channel you wish to remain on . You
may choose the desired scan mode as
described in the above steps.
H. Limited Band Scanner Operation
1 . To scan between a dial frequency and one of
the memory channels, enter the desired start­
ing frequency from the keyboard, and then
recall the memory frequency and press the
"#" key. The priority function will then be
activated. Now, press either the UP or DOWN
switch. If UP is pressed with the CLEAR­
MAN-BUSY switch in the MAN position , the
display will scan from the dial frequency to
the memory channel continuously. If the
CLEAR-MAN-BUSY switch is placed in the
BUSY position , the scanner will stop at a
channel where a carrier is present, and start
scanning again after 5 seconds.
2. For example, enter 1 45.750 into memory
channel 1 , and press "4750". Next, press
"DIAL", " 1 ", "MR" and finally "#". The
priority function will then be activated. When
the UP switch is pressed, the transceiver will
scan up to "5.750", and then the dis
�
lay will
jump back to 1 44.750 MHz, continuing the
scan up to 1 45.750 MHz again.
3 . If the DOWN key is pressed instead, the
display will scan from 1 44.750 MHz to the
low band edge of "4.000" and then jump to
the high band edge of "7.995 (5.9875,
7.9875)". From this band edge, the scan­
ning moves to the memory frequency of
"5 . 750", and then jumps to the dial frequen­
cy of "4. 7 50",
omitting
the frequencies in
between. This scanning function will repeat
itself until you stop on a specific frequency.

GENERAL
Note:
The following frequencies cannot be program­
med as band edges for the limited band
scanning function:
Model A, D, E :
"4.000", "4.005", "7.990'', "7.995"
Model B:
"4.000", "4.0 1 25", "5 .975", "5.987 5 "
Model C :
'
"4.000'', "4.0 1 25", "7.975", "7.9875"
I.
Miscellaneous
1 . To disable the keyboard and lock the FT-
208R on the frequency you are currently
using, slide the LOCK switch to the right.
This will provide protection against accidental
frequency changes. When the LOCK switch
is moved to the right, the display will indicate
"L". Locking the keyboard will not disable
the two-tone (DTMF) generator during trans­
mission .
2. To activate the memory backup in the CPU,
place the BACKUP switch in the ON position .
The built-in lithium battery will serve to
backup the memory frequency, programmable
shift frequency, etc. , while the power switch
is OFF, or while the transceiver is without
battery power. The battery has an estimated
lifetime of more than 5 years. After this
period, please ask your Yaesu Dealer for a
replacement.
3. The top panel HIGH-LOW switch may be set
to either the HIGH (2. 5 watt output) or LOW
(300 mW output) position, allowing you to
select different transmitter output powers.
Use the LOW position whenever possible to
prolong battery life.
J. Error Modes
1 . If you inadvertently program a frequency
incorrectly (e.g. , by pushing "73 53" and
DIAL), the display will indicate "E" to tell
you an error has been made. If this occurs,
push C (Clear) to return to the previous
frequency .
2. If you program a repeater shift outside the
amateur band, such as -600 kHz shift at
1 44. 500 MHz, the display will indicate "E"
when the PTT switch is closed. No transmis­
sion will occur under this condition.
