DISPLAY PROBLEMS

If the display does not turn on:
• Check the connection to the vehicle battery or pack.
• The vehicle battery may be too low to power the analyzer (below
1 volt). Fully charge the battery and retest.
• The analyzer's 9-volt battery may need to be replaced. Follow
the directions in "Replacing the Analyzer Battery" and replace the
9-volt battery (alkaline recommended).
• If the analyzer detects computer or ignition noise, a SYSTEM
NOISE message will appear. Verify that all vehicle accessory
loads are off and the ignition switch is in the OFF position. The
analyzer will automatically retest when the system noise is no
longer detected. If the SYSTEM NOISE message continues after
several retest attempts, disconnect the battery cables and retest.
• Batteries that are very weak or that have just been charged may
have sufficient electrical activity to alter test results. Should this
occur, an UNSTABLE BATTERY message will appear. The
analyzer will automatically retest when the battery has stabilized.
Fully charged batteries should stabilize quickly. Weak batteries
should be fully charged, then retested.
• If troubleshooting does not solve the problem, call 800-776-1995
to obtain service. See "Patents, Limited Warranty, Service" for
more information.
• If the analyzer does not power on when you press and hold the
MENU button, replace the 9-volt battery.
