The FDL01TU modem is a precision electronic device with a rugged
design that is intended for industrial applications. However, do not
install it where it will encounter excessive vibrations. In some cases,
isolation mounts may be used to isolate the modem from the
equipment’s vibration. Excessive vibration can permanently damage
the modem and/or cause it to malfunction.
Do not operate the FDL01TU modem in environments where it will
be subjected to excessive moisture (such as rain or water spray), dust,
oil, or other foreign matter (such as metal particles). Doing so may
permanently damage the modem and/or cause it to malfunction. If it
does become wet or contaminated, correct the situation, verify proper
operation and have any problems corrected before using it to control
other equipment. If necessary, the modem can be mounted inside a
protective or waterproof enclosure. If the enclosure is metallic, the
antenna must be mounted externally or the effective operating range
will be severely limited.
The FDL01TU is designed for indoor use. When using it outdoors,
the modem should be mounted in a waterproof enclosure and the
ambient temperature range should be checked to insure that it is
within the modem’s specifications. Always use the modem within its
specified environmental ranges.
