GENERAL
It is advisable to spend a little time selecting the best
locationforyourGX300.Themountingbracketcanbe
rotatedabove,beloworbehindtheradioenablingtheradio
tobemountedinawiderangeoflocations.Inaddition,
anoptionalushmountingkitallowstheradiotobeush
mounted in a panel or dashboard.
Keep the following points in mind when choosing
a location
• TheGX300isdesignedtomeetIP55*standard.
Werecommendedyouselectalocationthatwill
minimise excessive exposure to continuous rain
or spray.
• Selectalocationthatwon’texposeyourradio
to continuous direct sunlight which could cause
overheating.
• Ensurethelocationallowsafreeowofairaround
theheatsinkonthebackoftheradio.
• Themicrophoneandallcontrolsshouldbereadily
accessibleandtheloudspeakereasilyheardfrom
the normal steering or driving position. An extension
speakercanbeinstalledifrequired.
• Componentsandcurrentsintheradiocreate
magneticelds.Toavoidinterferencetocompasses,
shipsautopilotsensorsetc,theGX300shouldbe
mounted at least 300 mm from such devices.
INSTALLING THE UNIT
Afterchoosingalocation,holdtheunitwiththemounting
bracketattached,tothedesiredpositionandmarkthe
locationwithapencil.Removethemountingbracketfrom
theradioanddrillthemountingholes.Boltorscrewthe
bracketinplaceusinghardwaresuitableforthemounting
surface.Theunitissuppliedwithstainlesssteelscrews,
however,ifthemountingsurfaceisunsuitableforscrews
you may need to replace these with stainless steel bolts.
Rememberthexingsforoverheadmountedunitsmay
have to withstand heavy pounding when a vessel is in
rough water or being towed on a trailer or the vehicle is
on rough road.
DC CONNECTIONS
ConnecttheREDpowerleadtothePositive(+)sideofthe
batteryortoanaccessorypointinthevesselorvehicle’s
fuse box.
ConnecttheBLACKpowerleadtotheNegative(-)sideof
the battery or to a ground point in your vessel or vehicle.
NOTE: TheDCconnectorisnotwaterproof.Ifinstalledin
anexposedlocation,theconnectorshouldbeprotected
with waterproof tape to prevent water ingress.
IMPORTANT: TheREDpowerleadisttedwitha2Amp
fuse.Ifthefuseblows,useonlyastandard2Amp(3AG)
fuseasareplacement.Useofahigherratedfuseora
slow-blow type could result in damage to your radio which
would void the warranty.
Ifrequired,anextensionspeakermaybeinstalledto
improve sound levels in noisy environments or in locations
further away from the steering or driving position. For
locations exposed to water we recommend the SPK45
whichwilltthesuppliedadaptorthatconnectstothe

NOISE SUPPRESSION
27MHzmarineandCBradiocanbepronetoelectrical
and ignition interference. The reason is that electrical noise
is a form of AM transmission similar to that used by your
radioandyourradio’sreceiverisverysensitive.Inmost
cases,ignitionnoisecanbegreatlyreducedoreliminated
by selecting the Noise Limiter (NL)keyontheradio.In

which case we recommend you consult an auto or marine
electricianforadvicespecictoyourinstallation.
Higherfrequencyelectricalinterferencecausedbyelectric
motors and bilge pumps can be suppressed directly at the
motor terminals. Electronic interference caused by other
electronicdevicessuchasshndersisbestminimizedby
keepingtheunits,includingallwiringandcables,separate
fromyourGX300.
DISCONNECTING THE MICROPHONE
It is recommended that the microphone be left permanently
connectedtotheGX300,butifitmustbedisconnected,
proceedasfollows:
1. Insert a small screwdriver between the rubber boot
and the lip of the raised area on the front panel.
2. Ease the rubber boot out of the cable entry hole and
slide it along the cable away from the front panel.
 3. Identifythepluglockinglever,workthescrewdriver

Ensure that the location selected for in dash mounting is convenient
for the operator and that there is sufficient space behind the panel to
accommodate the body of the radio and allow a free flow of air.
Refer to page 13 of the Instruction Manual for more hints.
Once the most suitable location has been selected, mark and centre
punch the cross hair in each corner and drill a 12 mm diameter hole.
Mark a straight line from the outer edge of each hole to form a
rectangle. Cut to the inside edge of these lines.
Remove the backing paper from the metallic backing strips exposing
the self adhesive surface and fix them in position vertically at either end
of the hole on the rear side of the dashboard flush with the edge.
See figure 1
Place the GX600 through the hole. If the dashboard is subject to water
spray it may be beneficial to apply a thin bead of sealant to prevent
any water ingress between the body of the radio and
the dashboard.
The S/S brackets can now be fastened to the rear panel of the GX600
with the 4 S/S self tappers supplied. Note that the brackets can be
reverse mounted to allow for varying thicknesses of dashboards.
See figure 2
Insert the remaining metal-thread screws so that they bear down on
the two metallic backing strips and tighten until the GX600 is held
firmly in place.
Connect the power lead and antenna lead as illustrated in the
Instruction Manual.
