Internal Settings
Described here are a few internal settings you may
wish to make, as you become familiar with the FT-
1000, to tailor it to your particular station require-
ments. Be careful, however, to avoid tampering with
other internal controls, so as not to degrade alignment.
A few other internal controls are mentioned in the
Controls & Connectors chapter. For full alignment
details covering all internal controls, refer to the FT-
1000 Technical Manual.
Key Beeper Volume
This trimmer potentiometer sets the volume (rela-
tive to receiver signal volume as set by the AF control)
of the beep that sounds when one of the front panel
buttons is pressed.
CAUTION
This adjustment must be made with power
applied, and with the cover removed. Although
the voltages at exposed places in the trans-
ceiver are not dangerous to you, sensitive cir-
cuitry can be damaged by contact with metallic
tools. Therefore we recommend using a non-
metallic adjustment tool, if available. In any
case, avoid touching any components not in-
volved in the adjustment, and do not allow
anything to fall in the set while the cover is
removed.
¢ Disconnect the cables from the transceiver, and turn
the set upside-down on the table.

* Remove the ten screws shown below, and remove
the bottom cover.
* Now place the set on its side, reconnect the AC
power cable and antenna.
¢ Turn the transceiver on, and adjust the AF control for
normal volume on background noise on a common-
ly-used band,
* Locate VR3007 from the photo below, and use a
small screwdriver to adjust it for the desired beep
volume while repeately pressing a front panel key.
* Switch the transceiver off, disconnect the power
cable, turn the transceiver on its top again, and re-
place the bottom cover and ten screws removed
above (unless also setting $1001, as described next).
RX ANT Switch Selection Setting with BPF-1
Option (RF Unit Switch $1001)
As supplied from the factory, the RX ANT switch on
the front panel is configured to select a separate
receive-only antenna connected to the RX ANT jack on
the rear panel. If the BPF-1 Bandpass Filter Option is
installed, this switch can be reconfigured to select the
SUB RX ANT jack on the BPF-1 instead, by resetting
switch §1001 on the RF Unit. Note however, that set-
ting this switch to the E BPF position disables the
capability of operating split-frequency with a separate
receive antenna (see the schematics on page 29).
To gain access to the RF Unit, remove the ten
screws shown in the photo at the lower left, and remove
the bottom cover. $1001 is located near the back left
corner, as shown below.
