4.4.3 Reducing the optical transmitting power
The OZD Profi 12M P1x PRO and OZD Profi 12M Gxx (EEC) have a high
level of optical transmitting power. Optical overloading may result if these
repeaters are connected with non-OZD Profi 12M ... devices using plastic
optical fiber cables, particularly if short cable lengths are used. In this case
the optical transmitting power can be reduced.
The following details only apply for the S8 default position (S8 = 0).
 The DIP switch S6 is used to set the transmitting power of CH3.
 The DIP switch S7 is used to set the transmitting power of CH4.
CH3 is activated in this operating mode if S2 is in Position 1 and S3 is in
Position 0.
CH4 is activated in this operating mode if S4 is in Position 1 and S5 is in
Position 0.
CH3 is activated in this operating mode if S2 and S3 are in Position 1.
CH4 is activated in this operating mode if S4 and S5 are in Position 1.
 Leave S6 in Position 1 (default) if the optical fiber link to CH3 functions
correctly in this position.
 Leave S7 in Position 1 (default) if the optical fiber link to CH4 functions
correctly in this position.
