Safety Precautions And Instructions - T&D RTR-500MBS-A Getting Started Manual

Safety Precautions and Instructions

CAUTION Do not place or store in the following areas:
• Areas exposed to direct sunlight
• Areas exposed to excessive heat or high temperatures such as near fire or
heating equipment
• Areas exposed to static electricity
• Areas exposed to strong magnetic fields
• Areas exposed to dampness
• Areas subject to condensation or wet areas
• Areas exposed to excessive vibration
• Areas exposed to excessive smoke, dust or dirt.
CAUTION Other Precautions
• Use the unit in the specified operating environment. Do not use it for any
purpose other than for which it was designed.
• Condensation may occur inside the case when a unit is moved from one
environment to another where there is a great difference in temperature. Do
not use in areas susceptible to condensation.
• Do not use the unit in wet areas or places exposed to water such as
bathroom.
• When connecting the unit to your PC, make sure to follow all warnings and
directions from your computer manufacturer.
• We shall not guarantee the unit's operation if it has been connected to a PC
using a USB hub or a USB extension cable.
• Do not insert any foreign objects into any of the units' jacks.
• If the unit gets dirty, wipe it with a clean cloth.
• Make sure to remove dust and dirt from plugs of the AC adaptor and/or any
cables.
• Please note that this document has been written based on the presupposition
that details about contracts with an Internet provider, specific network
environments and the set-up of any other necessary equipment to enable
network connection has already been taken care of by the User and that
connection has been confirmed as workable.
CAUTION Notes and Precautions for Installing Wireless Communication Devices
When installing wireless communication devices take special care in selecting
locations so as to ensure proper communication. Note that even after a
successful installation, due to changes in environmental conditions,
communication errors may occur when restarting the system.
As far as possible, try to keep wireless communication devices away from metals
and set them up in high unobstructed positions.
• Please take note that in many instances, walls, floors, stairs, fences and
desks will contain metals. In order to carry out communication between
indoor and outdoor units, please locate indoor units near a
window so that radio waves can be easily transmitted.
• Please install these devices more than 30cm away from
walls or boards containing metal.
• If wireless communication devices are placed in a metal
containersuch as a freezer or refrigerator, the possible
wireless communication range will be shortened. In most cases radio waves
are transmitted via doors and door openings so place devices as near to
doors as possible.
As far as possible, keep the devices away from noise-emitting sources.
• Equipment such as some industrial instruments, electronic devices or
fluorescent lamps generate noise. Please place units more than one meter
away from such devices.
• Please place units more than 1 meter away from computers and other devices
which emit noise.
• Keep all wires as far away from wireless communication devices as possible.
Be careful about placing near any wiring or cables such as power supply
cables, telephone wires or LAN cables.
Because objects which contain lots of water, such as plants or soil, absorb radio
waves, we highly recommend that such objects not be placed between or near
wireless communication devices.
• When measuring temperature in a greenhouse it has been reported that as
plants grew, communication errors also increased.
• Do not place units directly on the ground.
Do not place devices which are using the same communication frequency
channel in the same area.
• If the same channel is used for multiple devices not only will more
communication errors occur, but battery life will also be shortened.
• If there is a possibility that devices with the same frequency channel will be in
wireless communication at the same time, please make sure to make changes
to the frequency channels so they are not the same.
