Table 5: Power Problems
Condition
Recommended Action
Battery Low indicator
lights steadily while
N-595 is connected to
AC and battery is not
discharged.
• Ensure that the N-595 is plugged into an operational
AC outlet and the AC indicator is on.
• Check the fuses. The fuses are located in the Power
Entry Module as indicated in
Fuse Replacement
on
page 52. Replace if necessary.
• Open the monitor as described in
monitor
Disassembly
on page 53. Verify the power supply's
output to the battery while on AC. Disconnect the
battery leads from the battery and connect a DVM to
them. The voltage measured should be 6.65 to 6.95
VDC and the current should be 320 to 480 mA.
Replace power supply if above values are not met.
• Check the harness connection from the bottom
enclosure to the User Interface PCB, as instructed in
User Interface PCB Removal/Replacement
on
page 64. If the connection is good, replace the User
Interface PCB.
