Troubleshooting Guide - Whistler GT-438G Owner's Manual

PROBLEM: Unit alarms when vehicle hits bumps.
• Check for loose lighter socket; tighten and clean.
• Check connections at both ends of the power cord.
Substitute another cord to determine if the cord is
defective. Return defective cord to the factory.
PROBLEM: Unit falses too much.
• If alarms are POP Ka, switch POP Mode to off.
• If the above option doesn't help, use a higher Ka Filter
setting or if Ka is not used turn Ka band off.
• If alarms are X or K band and due to radar based traffic
flow sensors or radar based vehicle blind spot
detectors, use a higher X/K Filter setting.
