3. BATTERY IN USE/
BATTERY LOW
indicators on the N -3000
light steadily but do not
on the N -3100 and
N-3200 while they are
connected to AC via the
external power supply.
All units are operational.
1. Ensure that a good docking connection
exists between the N-3000 and N -3100.
2. Check the N-3000 fuse. Replace if
necessary as indicated in the Disassembly
Guide section of the N -3000 service
manual.
3. Refer to the Troubleshooting section of the
N-3000 service manual.
4. BATTERY IN USE/
BATTERY LOW
indicators on the N -3100
light steadily but do not
on the N -3000 while they
are connected to AC via
the external power
supply. Both units are
operational.
Check the N-3100 fuse. Replace if necessary
as indicated in the Disassembly Guide
section of this service manual.
5. The N -3000 and/or
N-3200 and N -3100 do
not operate when
disconnected from the
external power supply.
1. The N -3000 or N-3200 battery may be
discharged. To recharge the battery, keep
the N -3000 connected to its external power
supply, or connect the N-3200 to AC power.
Confirm that the BATTERY CHARGING
indicator lights. The battery will be fully
charged when, after powering the unit off
and then on again, the BATTERY
CHARGING indicator does not light. The
monitors may be used with a less than fully
charged battery, but with a corresponding
decrease in operating time from that
charge.
2. If the battery fails to hold a charge, replace
it as indicated in the Disassembly Guide
section of the N-3000 or N -3200 service
manual.
6. BATTERY IN
USE/BATTERY LOW
indicator flashes during
DC operation.
There is 25% or less usable charge left on
the N -3000 and/or N -3200 battery. At this
point, if possible, discontinue use of the
N-3000/ N-3200 on battery power, connect it
to its external power source and allow it to
recharge (approximately 12 hours).
