Transport SR Series Installation Guide
Safety Notices
1) Please read all instructions before installing and powering the unit. You should keep
these instructions in a safe place for future reference.
2) The Transport SR family uses a 12V DC/1.5A power supply. If the power supply
shows signs of damage or malfunction, you should stop using it immediately - turn off
the power at the mains and disconnect it from the power supply before contacting
your supplier for a repair or replacement.
3) Changes or modifications not expressly approved by the party responsible for
compliance could void the user‟s authority to operate the equipment. Use only the
accessories, attachments, and power supplies provided by the manufacturer –
connecting non-approved antennas or power supplies may damage the unit, cause
interference or create an electric shock hazard, and will void your warranty.
4) Do not attempt to repair the products; they contain no electronic components that can
be serviced or replaced by the user. Any attempt to service or repair the unit by the
user will void the product warranty.
5) The Transport SR is designed for indoor use only and should be used in an
environment that is suitable for computers and other electronic equipment.
6) Ports that are capable of connecting to other apparatus are defined as SELV ports.
To ensure conformity with IEC60950 ensure that these ports are only connected to
ports of the same type on other apparatus.
