    CAUTION

    In the case of using at marine and coastal areas (within 3 km from theseaside), it is necessary to make measures against the damage from saltwater. For measurements against the damage from salt water to anODU, request to NEC.

    WARNING

    1. After turning ON the equipment, wait at least 1 minutebefore turning it OFF again. Repeatedly turning the powerON and OFF with in a short interval may cause the IDU tofail.

    2. The 43 V DC power is superimposed on the centerconductor of the coaxial cable between the IDU and theODU. Connecting a test set equipment directly to thisterminal may damage it and touching the coaxial cable coremay cause electrical shock.

    3. Persons performing servicing must take necessary steps toavoid electro-static discharge which may damage themodules on the IDU or cause error. Wear a conductivewrist strap connected to the grounded (G) jack on the frontof the equipment shelf. This will minimize static build-upduring servicing.

    4. Do not disconnect IF cable between the IDU and the ODUin operating condition, to avoid damaging the IDU andODU. Do not remove/connect the IF cable with IDU powerON, turn IDU power OFF before remounting the IF cable.

    SAFETY INFORMATION

    This safety information is prepared to protect the maintenance personneland PASOLINK+equipment. To avoid hazardous conditions, read thisInstruction manual thoroughly before equipment operation. The signalwords (Danger, Warning and Caution) are used in the Instruction manualand explained as follows:

    To avoid hazardous conditions, notes on the handling of equipment areprovided in the Instruction manual in places considered necessary, adhererigidly to the notes. And also the Caution and Warning labels are attachedto the IDU and ODU. And the meaning of each label is described asfollows:

    Signal Word Definition

    DANGERIndicates an imminently hazardoussituation which, if not avoided, willresult in death or serious injury.

    WARNINGIndicates an imminently hazardoussituation which, if not avoided, couldresult in serious injury.

    CAUTION

    Indicates a potentially hazardoussituation which, if not avoided, mayresult in minor or moderate injury ordamage to the equipment. It is alsosaid to alert against unsafe practice.

    Do not disconnect IF cable between the IDUand the ODU in operation condition, to avoiddamaging the IDU and the ODU.

    The -43 V DC power is superimposed on thecenter conductor of the IF cable between theIDU and the ODU. Connecting a testequipment directly to this terminal maydamage it and touching the coaxial cable coremay cause electrical shock.

    Be careful that top surface of IDU is hot.

    In a system using the OPT INTFC module, donot stare at the laser beam or look at it directlywith optical instruments. Otherwise, it mayhurt your eyes (Does not apply to Pasolink+PDH).

    WARNING!

    Turn off power at IDUbefore disconnecting cable.

    ! WARNINGTurn off power of IDU before disconnecting cable.
