TROUBLESHOOTING
Little maintenance is required. Regularly checking the condition of the

communication is functioning properly between the handheld and the truck is
all the maintenance that is necessary.
• If one of the system checks fails, contact BASE Engineering to
troubleshoot your handheld unit.
• Handheld repairs or modifications must be done by BASE Engineering to
maintain your warranty or certification.
