Troubleshooting
Critical operating conditions in the system such as high temperatures or a low
battery charge are indicated by LED signals, an acoustic signal, or both. The fol-
lowing sections provide information on the possible causes for these warnings
and some recommendations how to solve common problems when using the
R&S
TSME-Z3.
General troubleshooting procedure
The general troubleshooting procedure is:
1. Switch off the system unit.
2. Solve the problem causing the error, for example:
● Check the LEDs and analyze the acoustic signals as described in the fol-
lowing sections.
● Check the power supply.
● Check all connections.
● Check the environmental conditions (temperature, humidity, mechanical
vibrations etc.).
● Check whether the self-test completes successfully after switching the sys-
tem on.
● Consult the R&S
