Choosingtheproperroomandplacement

Install the device in a dry, sheltered, wellventilated room away from dust, moisture, insects,androdents(mice).

Room size should be such that the device can be placed in an upright position, and that technical personnel can easily perform routine or extraordinary maintenance. Evaluate the minimum size according to the power supplied by your model, taking into account that a volumeof2.5x2.2minheightisrequiredforatransmitterwith1KWofpower,andthatno othertransmissionorauxiliarydevicesshouldbepresentinthevicinity.

Placetheapparatusascloseaspossibletotheantenna,inordertopreventexcessivepower lossinthecables.Ifthisisnotfeasible,useantennacableswithlowlossandsuitablecross section.

Vents in the walls and any other openings must be fitted with metal gratings to keep rodentsandinsectsout,andmustbeequippedwithadustfilter.Makeabsolutelysurethat no water can seep through the vents, the air exhaust duct, or the antenna cable grommet. Alsoconfirmthatthefloorisnotatriskoffloodingduringheavyrainfall.

The preset overtemperature alarm will activate when the limit of 45C is exceeded.Itisadvisabletohangaminimum/maximumthermometeronthewalltoindicate variationsintemperature.

The room must be ventilated to ensure that the temperature never exceeds 35C. Such conditionscanNOTgenerallybemetwhentheexhaustcoolingairisnotpushedoutsideand isinsteadfedbackintotheroom.Thisisalsooccurringifmorethanonedeviceisinstalledin the same location. An efficient ventilation system with air exchange is thus required in the room.

Before connecting the power, ensure that it is appropriate and is able to support the consumptionrequiredbythetransmittermodelyouintendtouse. Your transmitter should not be used when near the lower voltage limit with high impedancelines:ifthelinevoltagefallsbelowacertainlimitatfull load,thelowvoltage sensor circuit could trigger a continuous, extremely dangerous on/off cycle. In such case, installanexternalvoltagestabilizer. Inordertoensureproperoperationandcomplywithsafetyregulations,propergroundingis required. Use the yellow/green lead in the power cable.

Thetransmitterisequippedwithnumerouscharacteristicsspecifictohighfidelitysystems;as such, it should be connected to modulating signals with the same care as a HiFi system, avoiding ground loops as much as possible. Under theseconditions, you will obtain optimal performance. Accordingtotheoperatingmodeandtypeofmodulationsourceavailable,youcanconnectto themodulationinputsinvariousways:

Wherethestereomodulationsignalisexternallygeneratedbyaseparatestereoencoder,the driver tone must be measured in the absence of audio modulation and all other auxiliary signals,asdescribedbelow: 1)Disconnectallsignalsfromtheexternalstereoencoderinput,andanyRDSorSCAsignals. 2) Select the VIEW AUX menu and confirm that the driver tone is now the only available signal. The standard level is as indicated above, 910% (21 to 20dB), and can be consequentlyadjustedontheexternalstereoencoderasrequired. 3)Reconnectthepreviouslydisconnectedsignals.

2.1.6Changingtheinputimpedance As previously explained, the input impedance on the modulation inputs can be changed. Selection of the input impedance is one of the very few settings that can only be changed internally,asfollows: 1)Disconnectthemains. 2) Unscrew the screws that hold the top cover in place (16 or more crosshead screws will requireremoval,dependingonthemodel). 3)Removethetopcoverandstoreitinasafeplace. 4)Identifytheinputcard.
