FCC ID: K6610613030 IC ID: 511B-10613030 Alignment VX-2100/VX-2200 (VHF) Alignment Introduction The VX-2100/2200 is carefully aligned at the factory for the specified performance across the frequency range specified for each version. Realignment should therefore not be necessary except in the event of a component failure, or altering version type. All component replacement and service should be performed only by an authorized Vertex Standard representative, or the warranty policy may be void. The following procedures cover the sometimes critical and tedious adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts subsequently are placed, realignment may be required. If a sudden problem occurs during normal operation, it is likely due to component failure; realignment should not be done until after the faulty component has been replaced. We recommend that servicing be performed only by authorized Vertex Standard service technicians who are experienced with the circuitry and fully equipped for repair and alignment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized Vertex Standard service technicians realign all circuits and make 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 warranty policy. Also, Vertex Standard reserves the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function and operation of the transceiver are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and realignment determined to be absolutely necessary. The following test equipment (and thorough familiarity with its correct use) is necessary for complete realignment. Correction of problems caused by misalignment resulting from use of improper test equipment is not covered under the warranty policy. While most steps do not require all of the equipment listed, the interactions of some adjustments may require that more complex adjustments be performed afterwards. Do not 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. 1/7 Vertex Standard Co., Ltd.

Correct alignment is not possible with an antenna. After completing one step, read the following step to determine whether the same test equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, in connected) before proceeding. Correct alignment requires that the ambient temperature be the same as that of the transceiver and test equipment, and that this temperature be held constant between 20 and 30 °C (68 ∼ 86 °F). When the transceiver is brought into the shop from hot or cold air, it should be allowed time to come to room temperature before alignment. Whenever possible, alignments should be made with oscillator 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 procedure are based on 0 dBμ EMF = 1 μV. Setup the test equipment as shown for transceiver alignment; apply 13.8 V DC power to the transceiver. Refer to the drawings above for Alignment Points. 2/7 Vertex Standard Co., Ltd.

The RF parameters are loaded from the file during the alignment process. In order to facilitate alignment over the complete switching range of the equipment it is recommended that the channel data in the transceiver is preset as the chart below. Channels Frequency BAND-LOW 134.000 MHz BAND-MID 154.000 MHz BAND-HIGH 174.000 MHz The alignment mode is accessed by “ Alignment mode” command from the computer whilst switching on. And the alignment tool operates it automatically. During the alignment mode, normal operation is suspended. Use the alignment tool program running on PC. The alignment tool outline Installation the tool This alignment tool consists, MS-DOS based, only one execute file " vx-2100adj.exe ". You make a directly as you think fit, and copy this file. That is all of the installation process. Boot the tool Change directly and input in command line, " vx-2100adj [enter] ", and boot the alignment tool. Enter to the alignment mode To enter the alignment mode, you have to power on the transceiver, and press [F10]. If entry succeeds, the transceiver generated a beep " p-p ".
