Planned Maintenance Inspection (PMI)
To assist maintenance of Dimetra products, Motorola publishes advice for recommended Planned Maintenance
Inspections (PMI). For each Motorola Part Number, the Inspection Schedule indicates whether any PMI action is
required/recommended, the regularity of the recommended/required action, and a brief description of the activity. The
Inspection Schedule also indicates Motorola's recommended PMI testing activities that should be carried out as part
of the PMI Schedule.
Always read the PMI Inspection Schedule in conjunction with the relevant Motorola or Motorola 3rd party suppliers
Standard Product Manuals and any Technical Information Bulletins (TIBs), which include the methods of access and
other useful information.
In additional to the Planned Maintenance Inspections, Motorola recommends to run the basic functional test every 24
months. These functional tests should include RF power, RF frequency, and Bit Error Rate measurements.
Motorola recommends regular site visits for other inspections, for example, site physical security checks, generator
maintenance, and so on.
Motorola also recommends the antennas and PSU/Battery/UPS tests and functional inspection according to the
respective manufacturers suggestions.
Caution: Ensure the ventilation holes and grilles on the are not covered.
Note: In the configuration with the backup battery: Check the backup battery charged by the MTS in
