Warning 

. 

 

Only  trained  and  qualified  personnel  should  be 

                 

allowed to install, replace or service this equipment.

 

 

 

 

 

RC903-V35FE1 provides Synchronous  Digital Interface 

complying  with  the  ITU  standard.  Before  power  on,  the  V.35 

cable   must   be  well   connected.   It   is   strictly   forbidden   to 

hot-swap  V.35  cable  when  the  converter  and  the  equipment 

connected by V.35 cable are both power on.

 

 

 

RC903-V35FE1 is integrated equipment. Move carefully and do

 

 

                 

not disassemble or mend it without the guidance of Dynamix 

technical engineer with the anti-static procedures.

 

 

 

 

The  equipment  must  be  grounded.  Do  not  disassemble  the 

equipment by yourself. It may cause unrecoverable damage. 

Dynamix will not be responsible for the damage by this.
