B - Antenna Coaxial Cable

C - Business Band Radio Power/Ground Cable

Never mount business band radio antenna to rear of cab. Never route antenna cable (B) near harness for electrical system controllers or operator controls. Failure to follow these precautions could expose operator to radio frequency energy levels higher than recommended by American National Standards Institute (ANSI) and/or could cause undesirable performance of electronically controlled systems.

Avoid personal injury. Disconnect battery ground cable before any electrical repair.

Final Tier 4/Stage IV Engines Only: To determine tractor engine type, see Engine Serial Number in Identification Numbers section of this Operator’s Manual. Do not disconnect battery until Selective Catalytic Reduction (SCR) system has had enough time to automatically purge system of Diesel Exhaust Fluid (DEF). If adequate time is not allowed for system to be purged, any DEF remaining can crystallize and plug system. At temperatures below -15° C (5° F), unpurged DEF will freeze and damage system components. If equipped with a battery disconnect system, a light next to the disconnect system is illuminated while auto-purge is in progress. It shuts off when complete and safe to disconnect the battery.

If tractor is not equipped with battery disconnect switch, wait at least 4 minutes after tractor stops before disconnecting battery.

• Roof Ground Plane: Grounded large antenna counterpoise foil under green cab roof allows installation of either ¼ or ½ wave antenna.
• CB Antenna: Normal CB antenna can be attached to factory installed NMO antenna mount through use of an appropriate adapter. Special CB antenna already equipped with NMO base may alternatively be used.
