MIQ/Blue PS

5 - 2

ba75573e04

05/2009

Range insufficient

Cause

Remedy

– Obstacle between the radio 

modules

– Remove obstacle

– Mount the MIQ/Blue PS in a 

higher position (e.g. on a 
pole)

– Make sure there is "visual 

contact" between the MIQ/
Blue PS modules

– If above mentioned 

remedies are not possible, 
bypass the obstacle with two 
radio links connected in 
series (see appendix).

– MIQ/Blue PS too close to the 

ground

– Mount the MIQ/Blue PS in a 

higher position (e.g. on a 
pole)

– Shielding by metal sun shield

– Use plastic sun shield
