Changing the Channel Steps
The
FT-257
’s synthesizer provides the option of utilizing channel steps of
5/10/12.5/15/20/25/50/100 kHz per step, as well as an automatic step selection based on
the current operating frequency (“AUTO”), any number of which may be important to
your operating requirements. The
FT-257
is set up at the factory in the “AUTO” con-
guration, which probably is satisfactory for most operation. However, if you need to
change the channel step increments, the procedure to do so is very easy.
1. Press the
[
SET/ATS
]
key to enter the Set mode.
2. Rotate the
DIAL
knob or press the
[

/
[

key to select
Set Mode Item 20:

.
3. Press the
[
SET/ATS
]
key momentarily to enable adjust-
ment of this Item.
4. Rotate the
DIAL
knob or press the
[

/

key to select the new channel step size.
5. When you have made your selection, press the
PTT
switch to save the new setting
and return to normal operation.
Receive Battery Saver Setup
An important feature of the
FT-257
is its Receive Battery Saver, which “puts the ra-
dio to sleep” for a time interval, periodically “waking it up” to check for activity. If
somebody is talking on the channel, the
FT-257
will remain in the “active” mode, then
resume its “sleep” cycles. This feature significantly reduces quiescent battery drain,
and you may change the amount of “sleep” time between activity checks using the Set
Mode:
1. Press the
[
SET/ATS
]
key to enter the Set mode.
2. Rotate the
DIAL
knob or press the
[
p
]
/
[
q
]
key to select
Set Mode Item 34:
RXSAVE
.
3. Press the
[
SET/ATS
]
key momentarily to enable adjust-
ment of this Item.
4. Rotate the
DIAL
knob or press the
[
p
]
/
[
q
]
key to select the desired “sleep” duration.
The selections available are 200 ms, 300 ms, 500 ms, 1 second, 2 seconds, or OFF.
The default value is 200 ms.
5. When you have made your selection, press the
PTT
switch to save the new setting
and exit to normal operation.
