7 Maintenance, Repair and Warranty
7.1 Introduction
The RU is designed and built to require no periodic maintenance. As long as the unit is
kept away from extreme temperatures and moisture, it should provide long-term, carefree
operation.
It is strongly recommended that no invasive procedures are performed on the unit in an
attempt to verify performance. See section 7.2 for recommended routine performance
variation checks.
7.2 Routine Checks
Although the RU is a low-maintenance unit, it is recommended to routinely verify the per-
formance of the RU by making test calls or detailed system checks on the actual radio
coverage. Several test calls should be made at different positions within each area to get
an overall picture of the system performance. This is by far the best way to check the sys-
tem as it tests the whole system from an operational viewpoint as seen by the users.
It is strongly recommended that no invasive procedures be performed on the unit in an
attempt to verify performance unless a serious problem with performance has been identi-
fied as described above. Any such invasive procedures are more likely to do damage to
the system and create intermittent performance than to be of any practical value.
7.3 Repair
Repairs may only be carried out by qualified personnel that are familiar with both the haz-
ards involved and the relevant statutory regulations. Unauthorized modifications or repairs
invalidate the warranty claim.

tion 7.4 (Troubleshooting).
