5.3 Exchanging the bleaching fibre
Note
The bleaching fibre must be exchanged when it is damaged.
The following factors indicate that that the lens or bleaching fibre is damaged or
dirty:
▪ Unclear spot diameter (no clear border of the red target beam)
▪ distinct loss of bleaching performance
Check the surface to see if the lens is dirty. To clean it, follow the directions under
the section "Cleaning the lens".

CAUTION
Contamination of the incoupling surface of the bleaching fibre
Dirty fibre end surfaces from fingerprints or dust can wear the bleaching fibre.
▶ When the bleaching fibre is not connected to the GENTLEray 980, the incoup‐
ling surfaces (device-side plug) of the bleaching fibre must be covered with the
provided dust caps.
Note
To protect the optical components in the device, the SMA socket in the device must
always be closed (with a bleaching fibre or protective cap).
Removing a defective bleaching fibre

▶ Put the cap on the lens connector ②. Do not remove!
