WARNING
The Notebook Power receptacle is “LIVE” whenever WavePort is plugged into a live AC power source.
The Module Power Switch can not
be used to turn this receptacle “Off.”
WavePort contains no user serviceable components. Do not remove WavePort’s cover plate.
Lethal voltages are present which could cause serious injury or death.
WavePort can receive power from one of three sources:
From External AC
: Connect the AC power cord to the LINE INPUT (100 to 240 VAC) receptacle on
WavePort’s cover plate; then plug the cord into a standard AC outlet. After the power cord is properly
connected, turn WavePort’s Module Power Switch “On.”
Note that the external AC power is also used to supply the Notebook power receptacle. As long as AC power is
supplied to WavePort, the Notebook receptacle will have power. The Module Power Switch is not in line with
the receptacle and cannot be used to turn it off.
From External DC
: Connect the DC power cord to the DC Power Input DIN5 connector on WavePort’s
cover plate. Connect the other end of the cable to a 12 to 30 VDC source, such as an automotive electrical
system. After the power cord is properly connected, turn WavePort’s Module Power Switch “On.” Note that a
CA-198 cable can be used to link a WavePort to a vehicle battery via a connection from WavePort’s DIN5
connector to the vehicle’s cigarette lighter.
From Internal Sealed Gel-Pack Batteries
. When the Module Power Switch is “On,” internal gel-pack
batteries will supply power to modules if insufficient power is available from an AC or other another DC source.
Fully charged batteries will provide approximately 30 minutes of operation.
