IMPORTANT- This system is designed for Univenal Installation of many different Manufacturen equipment. When
required, specific instructions or templates included in this package are provided when the Universal Mounting Method is
not applicable.
I. Selection of the Mounting Area
Note: Specific templatesareincluded for J.I. CaseModel 580K equipment. Useuniversal templatefor John Deere, Caterpillar,
Fiatallis and other manufacturers.
A. This product is designedfor overhead (roof) mounting in vehicles where a dashmounted radio is not practical. The usual
application includes construction vehicles, agricultural vehicles, and othersprovided they havean enclosedcab.
B. Since the product is to be mounted overhead, specialconsideration should be given to placement,accessibility for useand
safety.As for placementtheunit shouldbecenteredabovetheoperatorandslightly forward. Accessibility to theradio's controls
andfunctions is necessary,sothe unit shouldbelocatedwithin reach.Safetycannotbeignored. Usagemust benot distract the
operator any more than a conventional dashmounted unit would. Also sincethe unit is to be mounted overhead. you must
considerit asanormal obstruction that theoperatorcould comein contactwith. This isespeciallytrue in vehicles that normally
operateoff road.
C.With the three previous main considerations examined, you should now selectthe mounting area.The final consideration is
mechanical mounting capabiltiy. Examine the mounting illustration andverify the selectedareais suitable for drilling of the
two bolt holes,wiring accessetc.Usethe templateprovided to verify sufficient spaceexistsonthe mounting areato acceptthe
unit.
2. Pre-InstalIlation Checks
A. Determine the cabroof structure. It is like Fig. A, Fig. B, or Fig. C.
B. If it is like Fig. A, you must install the CE-3100 asshown in Fig. I
C.1f it is like Fig. B, you must install the CE-3100 asshown in Fig. 2
C.1f it is like Fig. C. you must install the CE-3100 asshown in Fig. 3
3. Antenna Installation (Roof Mounting)
A. The universal antennamaybemounted on the top of the roof or on the sideof the cab.Refer to the instructions included with
the antenna for side mounting.
Note:to insure a leak proof mount.
B. AI\vavs mount the antennawithin reach of the radio (the cableis 59" long).
C.It is easierto drill the antenna mounting hole and mount the antennabefore proceeding with the radio installation.
D.T\vo typesof mounting conditions mayexist:
I. If the roof hasno liner or if the liner is tight against theundersideof the roof (no air gap),youwill drill a 3/4" hole through
the roof and andthe roof liner (total thicknesscannotexceed3/8"). Also the hole mustbelocatedoutside the mounting plate
or it will interfere with the antenna mounting.
2.If the roof hasa roof liner and there is an air gap of at leasttwo (2") inchesbetweenthe liner and the underside of the rrof.
you will drill a 3/4" hole only through the roof (do not drill through the liner). You can also mount the antenna anywhere
including directly abovethe radio areasisncethe 2" gapwill prevent any interference.
E. Oncethe hole is isdrilled, install the antennabyfollowing the instructions included with theantenna.Usesealantto insure the
antenna mounting hole will not leak.
F. If the vehicle hasa roof liner, you will haveto drill a 3/8" hole in the liner to route the antennacable out of the roof. This
hole should be drilled ascloseto the "Wiring Access"hole shown on the radio mounting.
Note: If roof mounting of the antenna is not practical, the antennacan be mountedon the sidesofthc cab or other areas(se(
antenna instructions). This location should always allow the antennato be ashigh aspossible for maximum reception
4. Wiring (See Fig. 5, 6)
A. Connect the antennacable to the socketon the rear of the radio.
B. Connect the Redpower lead to (+) 12volts.
C. Connect the Black ground lead to the vehicle's chassisground.
Caution: For usewith 12 volt negative ground system only, For 24 Volt Neg. ground, usewith converter.
