Hook fi lter (option)

A hook fi lter is available as an option. New products will be delivered without the fi lter. The acoustical testing and calibration on Fonix test system needs to be always done without the fi lter.

1. Replacement of the fi lter:Place the hook wth fi lterstick into the hole. Press until a small click sound appears and slide the HI towards the new fi lters until the used fi lter is off.

2. Mount the new fi lter:Press the HI over a new fi lter. Pull the instrument straight up and a new fi lter will be placed into the hook.

3. Fit the fi lter:Press the hook with the new fi lter fi rmly down in the hole to ensure that the fi lter is securely fi tted into the hook.
