Connection Ofheadphones; Adjusting The Front Feet - Yaesu FT-100D Operating Manual

Installation
ACCESSORY INTERFACING
Receiver Accessories (Tape Recorder, WeatherFax Demodulator, etc.)
Connection of a tape recorder, WeatherFax demodulator, or other such receiver accessory
is easily accomplished by using the DATA jack's DATA OUT (1200 bps) terminal (Pin 5)
and Ground (Pin 2). The audio output is fixed at 100 mY, with an impedance of600 O.
CONNECTION OF HEADPHONES
The FT -1 OO's extremely compact size does not permit inclusion of a headphone jack.
Direct connection of 40 or SO headphones to the Speaker jack, however, could cause
hearing damage, due to the high level of audio output available at that jack.
To connect headphones to the Speaker jack, build a small
attenuator circuit into a small adapter box. Connect a
lOon
y,
W resistor in series with the headphone line, and
a
Ion
Y,W
resistor shunt to the shield (ground).
ADJUSTING THE FRONT FEET
The two front feet of the transceiver allow the trans-
ceiver to be tilted upward for better viewing. Sim-
ply fold both feet forward to raise the front of the
transceiver, and fold them back against the bottom
case to lower the front of the FT -100.
