The GX2360S has been carefully aligned at the factory for the specified performance
across the marine band.
Realignment should therefore not be necessary except in the event of a component
failure. All component replacement and service should be performed only by an authorized
Standard Horizon representative, or the warranty policy may be voided.
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 are replaced, 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 Standard Horizon
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 Standard Horizon 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, Standard Horizon, a division of VERTEX STANDARD, must
reserve 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 the need for 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.

All component replacement and service should be performed only by an authorized Standard Horizon representative, or the warranty policy may be voided.
  • Page 2 If 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 this procedure are based on 0 dBµ = 0.5 µV (closed circuit). Vertex Standard Co,. Ltd.
  • Page 3 Setup the test equipment as shown below. Connect the DC voltmeter to the test point (TP1009). Set the channel to CH16. With the PTT switch pressed, adjust TC1002 so that DC voltage is 1.5 V ± 0.1 V. Vertex Standard Co,. Ltd.
  • Page 4 Adjust power at high and low in the transmit mode, and confirm power in the specified bandwidth. – High Power Setting -- Connect the wattmeter and 50 Ω dummy load to the antenna jack. Press the SCAN key, then appear |ALIGNMENT | on display. |01:HI PO Vertex Standard Co,. Ltd.
  • Page 5 RF power is between 24 W ±1 W. Set transceiver to low power and confirm that RF power is between 0.8 W ±0.2 W. Confirmation of Deviation Adjust deviation in the transmit mode. Set the output of the AG to 1 kHz and 100 mV. Vertex Standard Co,. Ltd.
