Service Manual
VX-1400 Series
Introduction
This manual provides the technical information necessary for
servicing the VX-1400 HF Transceiver.
Servicing this equipment requires expertise in handing sur-
face-mount chip components. Attempts by non-qualified per-
sons to service this equipment may result in permanent dam-
age not covered by the warranty, and may be illegal in some
countries.
Two PCB layout diagrams are provided for each double-sided
board in this transceiver. Each side of the board is referred to
by the type of the majority of components installed on that side (“Side A” or “Side B”). In most cases one side
has only chip components (surface-mount devices), and the other has either a mixture of both chip and leaded
components (trimmers, coils, electrolytic capacitors, ICs, etc.), or leaded components only.
As described in the pages to follow, the advanced microprocessor design of the VX-1400 Transceiver allows a
complete alignment of this transceiver to be performed without opening the case of the radio; all adjustments
can be performed from the front panel, using the “Alignment Mode” menu.
While we believe the information in this manual to be correct, VERTEX STANDARD assumes no liability for
damage that may occur as a result of typographical or other errors that may be present. Your cooperation in
pointing out any inconsistencies in the technical information would be appreciated.

1) This transceiver was assembled using Pb (lead) free solder, based on the RoHS specification.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this apparatus. The
solder stated above utilizes the alloy composition required for compliance with the lead-free specification, and any solder
with the above alloy composition may be used.
2) Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.
