The HX400 has been carefully aligned atthefactoryforthespecifiedperformance across the
marineandLMRbands.
Realignmentshouldthereforenotbenecessaryexceptintheeventofacomponentfailure.
All component replacement and service should be performed only by an authorized
STANDARDHORIZONrepresentative,orthe

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
normaloperation,itislikely
dueto componentfailure;realignmentshould not bedone until
afterthefaultycomponenthasbeenreplaced.
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,ifafaultissuspected,contact
thedealerfromwhomthetransceiverwas
purchased for instructions regarding repair. Authorized STANDARD HORIZON service
technicians realign all circuits and make complete performance checks to ensure compliance

Problems caused by unauthorized attempts at realignment are not covered by the warranty
policy.Also,STANDARDHORIZONmust reserve the rightto change circuitsandalignment
procedures in the interest of improved performance, without notifying owners. Under no

causedbymisalignmentresulting
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.
