To reduce the risk of damage to the equipment, pull by the plug body rather than the output cord
when disconnecting the equipment.
Do not operate the supply if it has received a sharp blow, been dropped, or otherwise damaged. Do
not disassemble the supply.
Warning: Before connecting the external power source and the modem, make sure that the power source matches the
modem’s voltage and current requirements.
2. Antenna Installation
Warning: To avoid the equipment serious damage, do not switch the modem to transmit mode if RF antenna is not
connected!
Select the type of antenna that best fits your application and the one that offers the highest dB gain. In
addition, setup your system in the highest possible location to minimize obstacles between the
transmitting and receiving systems. Always place the antenna on the highest point available. At a
minimum, set the antenna to at least ten feet above the terrain using an antenna mast.
Use coaxial cable and connectors that are impedance-matched with the radio equipment, and make sure
to use the shortest length of cable to move the signal between the radio and the antenna.
