Check the AC and N-200 interface/powerbase
connections for proper AC power supply.
Check battery operation. If the battery is discharged,
connect the N-200 to the interface/powerbase. Plug the
power cord into an outlet supplying the appropriate
mains voltage. The interface/powerbase requires a
minimum of 14hours to recharge the N-200 battery
completely.
Check AC fuse.
The battery may be discharged. To recharge the
battery, connect the N-200 to the interface/powerbase.
Plug the power cord into an appropriate AC power
outlet and confirm that the BATT IN USE indicator is
off. A minimum of 14 hours is required to recharge the
battery completely.
The battery pack or battery charger circuit may be
defective, or the battery fuse may be open.
Check the N-200/interface/powerbase connection. The
BATT IN USE indicator turns off to confirm correct
connection.
Replace the power cord, check the connections, or try
another AC outlet.
Check fuse.
