Troubleshooting
This section contains information to help diagnose system problems. The Diagnostic Menu and Report can help
determine if a probe is functioning correctly. The sections describing system boots help determine if the console
hardware is functioning correctly.
A brief section is included that describes how install a software upgrade. Other sections detail CPU and Power Supply
board replacement should the self-diagnostic programs indicate a hardware failure.
At the end of the Troubleshooting section you will find a list of specifications and a chart showing the probes that can be
used with the TLS-HLD Console.
Dual-Function Front Panel Keys
Two of the six front panel keys have dual functions [Figure 18].
Figure 18. Dual-Function Keys
Pressing the Enter key down for an extended period (longer than 2 seconds) will change the system language to the next
available language queued in software. Repeat this procedure until the desired language is displayed.
Pressing the Back key down for at least 2 seconds will change the system setup units. Repeat this procedure until the
desired units are displayed.
A short beep from the console beeper will inform the operator that these keys have been held in long enough to select the
alternate function. When the operator is ready to return to the originally programmed language and/or units, switch the
console power Off and then back On. The system will perform a warm boot and return to the originally programmed
language and units.
Probe Diagnostic Menu
