GNSS interference
CAUTION – The GNSS antenna may experience interference if you operate the vehicle within 100 m (300 ft) of
any power line, radar dish, or cell phone tower.
Installation
CAUTION – Do not mount the DCM-300 modem in direct sunlight or in areas of high heat. This will cause
degraded performance.
CAUTION – Do not attempt to power the display without the TM-200 Module.
CAUTION – If the vehicle has a master electrical disconnect, make sure the power cable ground connections are
not directly attached to the battery terminal. Attach the ground connections of the power cable to the chassis
side of the main disconnect so that it is as close as possible to the battery, but still gets disconnected when the
master disconnect is turned off. Failure to connect the power cable ground will cause damage to the display.
CAUTION – Make sure the vehicle power is off when you are connecting system components.
CAUTION – Wireless, cellular, radio and GNSSsignals can interfere with each other. For best performance,
mount antennas at least 1 meter away from each other.
Vehicle setup
CAUTION – If you select a Vehicle Profile that is not suitable for your vehicle, you may experience degraded
system performance.
CAUTION – If you delete a vehicle, all information about the vehicle will be erased.
USB socket
CAUTION – Do not remove the USB drive from the socket while the display is writing to or from the drive. This
will corrupt the data.
CAUTION – Do not use a USB drive in each USB socket at the same time. If you are attempting to upgrade
firmware using a USB drive and another USB drive is already in one of the sockets, the firmware upgrade will
fail.
