Operation
2.1 Assembling HF HATS Types 5128-C and 5128-D
HF HATS Types 5128-C and 5128-D can be used free-standing, or supported on a tripod using
adapter UC-5290 (Fig.1.2). The adapter screws onto the top of a tripod. The torso can then be
fitted onto it and secured by tightening the locking nut.
If HF HATS is to be used free-standing, it is advisable to fit the extra feet supplied (UA-1043,
Fig.2.1) to give it extra stability. To do this, unscrew the small rubber feet from the base of the
torso. Then, ensuring that the spacers supplied are placed between the base of the torso and the
extra feet, secure the extra feet with the screws supplied. The small rubber feet can be fitted to the
extra feet if desired, as in Fig.2.1.

2.2 Utilizing the Mouth Simulator
The loudspeaker of the mouth simulator can be driven directly from any voltage source. The
mouth simulator can be driven with a maximum continuous voltage of up to 0.7 V
rms
. Input levels
of up to 1.5 V
rms
can be safely used for periods of less than 2 s. If voltage is exceeding this time
frame, the integrated amplifier will go into protection mode (muting the loudspeaker) for 2 s.
