3. Controls & Connectors - Top Access Panel Controls
(7) Cd PITCH DIP Switches
Set these switches to select your desired CW tone
pitch, as shown below. The transmitter sidetone fre-
quency, and receiver IF passband and display offset
from the BFO (carrier) frequency are all affected.
(8) BACKUP Slide Switch
Keep this switch in the on position to retain all
memory and vfo settings during power-off periods,
There is no need to turn this switch off unless you plan
to store the transceiver for a long period without use.
(10) PHONE Slide Switch
This switch selects between three possible modes of
dual-receive audio when stereo headphones are con-
nected to the front pane! PHONES jack.
The @ix (mixed) mode is a combination of the other
two modes described below: audio from both receivers
can be heard in each ear, but the sub receiver audio is
attenuated in the left ear, and the main receiver audio is
attenuated in the right.
In the st (stereo) mode, audio from the main recei-
ver is heard only in the left ear, and audio from the sub
receiver is heard only in the right ear.
In the mono (monaural) mode, audio from both main
and sub receivers is combined and heard the same in
both ears (as from the loudspeaker when headphones
are not used).
Note that both receivers must be activated by the
DUAL button on the front panel, and the RX MIX control
on the front pane] must be set near the center position,
' ' to hear both receiver channels.
(9) MARK Slide Switch
Set this switch on to activate the internal 10-kHz
marker generator, for testing or calibration purposes.
For normal receiver operation, this switch must be off.
This switch does not affect dual-channel audio from
the AF OUT jack on the rear panel, which should be
processed by an external stereo amplifier.
Power Up Selections
By pressing and holding certain combinations of keypad keys while switching on the FT-1000, you can perform
several functions and make some simple settings,
To reset the microprocessors and clear all memories, turn the transceiver off, and then press and hold the SUB
and ENT keys at the lower corners of the keypad while also pressing the POWER switch. Normally there should be
no need to do this, but it is provided for servicing purposes, to return all memories and other settings to their
default states. Note that it is not necessary to turn off the memory backup to reset the microprocessors.
To perform the "Las Vegas" diagnostic test of the display and its microprocessor, and to check the ROM version
of your transceiver, press and hold the 1.5 and 7 MHz band keys (yellow-labelled 1 and 3 keys) at the upper
comers of the keypad while switching the power on. This procedure will not erase any memorized data. After
_ testing the display segments, "YAESU" will be displayed, followed by a ROM version number. After a few
seconds, the display will return to normal operation.
Pressing the 29 MHz band key (yellow-labelled 0 key) while switching on the power causes the 10-Hz digit on
the main and sub vfo displays to be blanked, Repeat the same step to unblank it.
Pressing the 10, 14 and 18 MHz band keys (yellow-labelled 4, 5 and 6 keys) simultaneously while switching
the power on toggles the manner in which the displayed frequency is affected when changing modes. In its
default state, switching to and from CW, packet or RTTY modes causes the display to change by the amount of
_ Offset selected by the CW PITCH and PKT/RTTY DIP switches in the top access panel. After holding these keys
while switching power on, the display will continue showing the same frequency when changing to and from
these modes, However, the actual BFO (carrier) offsets, set by the DIP switches, relative to the display and IF
bandpass are unaffected, regardless of either display state.
