Restrictions Regarding
Level-3 Repairs
Only TEL and the ISC should carry out level-3 repairs. The level of
technology employed in the TM8100 generation of radios is an order of
magnitude greater than in earlier generations. This greater sophistication
demands special equipment and techniques for level-3 repairs. Although
other service centres are strongly advised not to attempt such repairs,
those with sufficient resources and skilled technicians may wish to do so.
These service centres should contact Technical Support for assistance and
for the necessary documentation. TEL does not offer accreditation for
level-3 repairs to any service centres other than the ISC.

Introduction This subsection describes the product codes used to identify different
products of the mobile radio product line. The product-code scheme in
general is first explained, and then the product codes for the radio body
and control head in particular. The purpose is solely to enable service
technicians to identify the radio body and control head of a radio that has
been delivered for repair.
