9. System Administration
9.1 Troubleshoot Error Codes
When an alarm is detected, the ERROR LED will light and the MCU’s STATUS LEDs
will display an alarm code.
If the error code refers to a Base Station problem, the Base Stn LED will indicate
which Base Station has the problem. If more than one Base Stn LED is on, the error
code refers to the lowest numbered Base Station with an error. Use the STEP button
to select another Base Station to display its error code.
For additional assistance in troubleshooting your system, please contact the
SpectraLink Customer Support Hotline at (800) 775-5330. The hotline is open
Monday through Friday, 6 a.m. to 6 p.m. Mountain time.
9.2 Troubleshoot Handset Features
If handset features are not working properly, disconnect the handset from the MCU
and plug a wired telephone into the port. The telephone should be the same type as
the emulated telephone. Refer to the appropriate section of the
LinkPlus Interface
Guide
for your PBX type.
Test the features on the wired telephone.
• For analog MCUs, verify that feature access codes and switchhook flash work
correctly.
• For digital MCUs, verify that features are assigned to the correct keys and are
working properly. Refer to the appropriate
for button mapping information for
the brand of telephone system at your location.
Certain four-wire telephones (such as MERLIN LEGEND) use a
different connector on the phone than on the back of the MCU.
Therefore you may need phone cord or an adapter to perform these tests.
