REDBACK Q 2001
SYSTEM CHECK MODE
System check Mode is included for audible testing of larger
speaker installations. It allows the Q 2001 to run at full output
for a period of approximately 6 minutes so the installer can walk
around the install to check sound is present on all speakers.
To activate this mode connect the test leads to the load to be
checked, ensure that an amplifier is not connected. Make sure
the Q 2001 is OFF then press the TEST button and hold for 2 to
3 seconds "SYSTEM CHECK" will display on the LCD and a
1kHz tone will be put out the test leads.
SWITCHING OFF
To switch off the The Q 2001 all you need to do is press the
TEST button again. The LCD will display "OFF" for a short time
then the unit will power down. The Q 2001 is also equipped with
an auto power off function. The unit will automatically power
down after a period of 20 seconds in Single test mode and 6
minutes in System check mode, saving precious battery life.
BATTERY INSTALLATION AND OR CHARGING.
"LOW BATTERY" will display on the LCD when the battery
requires replacing or if a rechargeable 9V Nicad/Nimh battery
needs charging (not supplied).
To replace or install the 9V (type 216) battery required to power
the Impedance Meter, simply slide off the battery compartment
on the back of the unit. Remove and unclip the old battery from
the connector and replace it with a fresh battery. Slide the cover
back until it locks into place.
To recharge an installed Nicad/Nimh battery connect a 12VDC
source (car battery, cigarette lighter socket or plug pack)
>300mA with a 2.1mm centre positive plug to the Charging
socket located on the top of the Q 2001. "CHARGING" will dis-
play on the LCD along with the charge %. When the charge %
reaches 100% the Q 2001 will stop charging and display
"CHARGE FINISHED" on the LCD. The charger can then be
unplugged. The inbuilt charging circuit is a slow charger and will
take up to 12 hours to charge a completely flat battery.

NOTE:
1) The Q 2001 will not function as an Impedance meter when
charging.
2) The charger can be removed at anytime during charging
though battery life will suffer.
3) The Q 2001 will still function when "LOW BATTERY" is being
shown on the LCD but the measured results may be out by as
much as 10%.
IMPORTANT GUIDELINES:
Don't connect the meter to a line that has an amplifier
attached to it. The impedance of the output transformer of
an amplifier is extremely low and you could be easily be
looking for a non-existing short.
Don't connect the meter to an active line. You will damage
the meter with the applied voltage.
Don't continue to use a battery once the "LOW BATTERY"
is being shown on the LCD. The readings you will get will
be incorrect.
