High-frequency Head and Torso Simulator (HF HATS) Type 5128 – User Manual
32
The handset’s ECRP is directly over the front support when the handset is correctly mounted in
the cradle. The rear support can be positioned in any one of the five sockets available for the
centering forks and is held in place with a knurled locking ring.
The end stop controls the positioning of the phone along its longitudinal axis, and similarly to the
supports, can be extended or retracted using an adjustment knob.
The centering forks, supports, support feet and end stop have etched graduations.
