Repair procedures and fault diagnosis
General
The information in this section should be read in conjunction with the appropriate
flowchart. See below to determine which flowchart you should view.
You should not disassemble the 2110 until the preliminary checks in the Repair flowchart
are completed. If the Repair flowchart refers you to any of the other flowcharts, you
should disassemble the transceiver only when this is indicated in the process.
NOTE
The fault diagnosis and repair procedures assume that the transceiver has
no software or hardware options installed. See
page 115, Options to
identify any specific testing for options.
NOTE
All fault diagnosis should begin with the Repair flowchart (see
Figure 29 on page 95 ). Check voltages on boards as required.
NOTE
All measurements for output power are in PEP.
WARNING
When taking measurements, keep the earth lead on the probe as short as
possible.
