Vest model 104(105,205) Hill-Rom - need help with configuration for 4years old CFboy

Hello, please can someone help us with configuration and adjusting Vest model 104 (105,205) Hill ROM for 4 years old boy with CF? My friends in Central Europe bought 104 model ...and doctors have no experiences with the vest system in our country. How setup (what values): oscillation frequency (5-20Hz), force (1-10) and duration of treatment (in minutes) for 4year old boy. How many times a day is the treatment ok for him? Should they buy for him Chest Vest or Full Vest? Thank you for any tips!
