1.2 General
This manual includes all the information necessary to maintain peak product performance and
maximum working time. This detailed level of service (component-level) is typical of some service
centers, self-maintained customers, and distributors.
Use this manual in conjunction with the ASTRO Digital XTL 1500 VHF/UHF Range 1/UHF Range 2/
700–800 MHz Mobile Radio Basic Service Manual (Motorola part number 6815854H01), which helps
in troubleshooting a problem to a particular board.
Conduct the basic performance checks first to verify the need to analyze the radio and help pinpoint
the functional problem area. In addition, you will become familiar with the radio test mode of
operation which is a helpful tool. If any basic receiver or transmitter parameters fail to be met, the
radio should be aligned using the radio alignment procedure described in the
ASTRO Digital
XTL 1500 VHF/UHF Range 1/UHF Range 2/700–800 MHz Mobile Radio Basic Service Manual .

not avoided, might result in equipment damage.

which, if not avoided, could result in death or injury.
