EH017M90B Technical Supplement Specifications.2 Exploded View check with your dealer. 3 Exploded View realignment should not be done until after the faulty component has been replaced. We recommend that servicing be performed only by au- thorized Vertex Standard serv

2、ice technicians who are ex- perienced with the circuitry and fully equipped for repair and alignment. If a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized Vertex Standard service tech- nicians realign all circuits and make

3、complete performance checks to ensure compliance with factory specifications after replacing any faulty components. Those who do undertake any of the following alignments are cautioned to proceed at their own risk. Problems caused by unauthorized attempts at realignment are not covered by the warran

4、ty policy. Also, Vertex Standard reserves the right to change circuits and alignment proce- dures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempt- ed unless the normal function and operation of the trans- ceiver are clearly un

5、derstood, the cause of the malfunc- tion has been clearly pinpointed and any faulty compo- nents replaced, and realignment determined to be abso- lutely necessary. Required Test Equipment The following test equipment (and familiarity with its use) is necessary for complete realignment. Correction of

6、 prob- lems caused by misalignment resulting from use of im- proper test equipment is not covered under the warranty policy. While most steps do not require all of the equip- ment listed, the interactions of some adjustments may re- quire that more complex adjustments be performed after- wards. Do n

7、ot attempt to perform only a single step unless it is clearly isolated electrically from all other steps. Have all test equipment ready before beginning and, follow all of the steps in a section in the order presented. ? RF Signal Generator with calibrated output level at 500 MHz ? Deviation Meter (

If not, remove the test equipment (except dummy load and wattmeter, if connected) before proceeding. Correct al

10、ignment requires that the ambient temperature be the same as that of the transceiver and test equipment, and that this temperature be held constant between 68 86 F (20 30 C). When the transceiver is brought into the shop from hot or cold air, it should be allowed some time to come to room temperatur

11、e before alignment. Whenever possible, alignments should be made with os- cillator shields and circuit boards firmly affixed in place. Also, the test equipment must be thoroughly warmed up before beginning. Note: Signal levels in dB referred to in the alignment pro- cedure are based on 0dB = 0.5V. 1
