Problem Isolation Steps
Resolution
Check
that the ISR sensor is located
away from possible sources of IR
interference.
Direct sunlight and Plasma monitors can adversely
affect performance.
Check
that a known good microphone
works with the system being
tested.
If the intermittent operation stops, the original
microphone is likely the cause of the problem. If
the problem continues, the ISR sensor may be the
cause of the problem.
Check
proper connection of Cat 5 sen-
sor cable.
Make sure the Cat 5 connector is fully inserted and
locked into 805 preamp and ISR.
Verify
proper wiring of Cat 5 sensor
cable.
If Cat 5 cable has been reterminated, or if a differ-
ent type third-party cable has been used, the new
connector may be mis-wired. Replace with known
good cable to verify.
REDMIKE/RED-
MIKE Volume
Control (RMT/
RMV) will not
power on
Check
that the correct battery is being
used.
Use the Lightspeed NH2A27 NiMH rechargeable
sensing battery as it is the only kind of battery that
will properly charge with the RMT/RMV.
Check
that the battery is installed prop-
erly.
Ensure that the polarity is observed.
Check
that the battery is charged.
Substitute a known good battery and see if it
charges in the microphone. If it does charge,
replace worn or defective battery. Typical battery
life is 1-2 years.
Check
that battery contacts are not
obstructed.
Ensure that there is no object preventing good
contact between the battery and contacts.
RMT/RMV
won't charge
Verify
that the correct battery is being
used.
Use the Lightspeed NH2A27 NiMH rechargeable
sensing battery as it is the only kind of battery that
will properly charge with the RMT/RMV.
Check
that the RMT/RMV charging
circuitry is working properly.
Substitute a known good battery and see if it
charges in the microphone. If it does charge,
replace worn or defective battery. Typical battery
life is 1-2 years.
Verify
that the RMT/RMV is being
seated properly in the cradle
charger.
When the RMT/RMV is properly inserted in the
cradle, the LED on the charger should turn solid
red.
Verify
that the cradle charger is working
properly.
The LED on the cradle charger should turn solid
red when the microphone is inserted. If no LED's
light, try using a known good cradle charger. (If
there is a blinking red LED, that indicates a charg-
ing error most likely related to improper battery
type.)
Verifiy
that the cradle charger power
supply is not damaged or defec-
tive.
Try known good charger power supply.
