E-3
POWER SOURCE
The SCR-75 operates on two 1.5V DC “AA” size (UM-3) alkaline batteries (Not Included)
or with an AC-DC adaptor with 3V DC ~ 600mA output (Not Included).
A. BATTERY OPERATION (BATTERIES NOT INCLUDED)
1.
Open the battery door located on the back of the unit.
2. Follow the polarity diagram (+ and -) shown on the back of the cabinet, and insert 2
'AA' (UM-3) batteries (not included), and close
the battery door.
IMPORTANT:
Be sure that the batteries are installed correctly. Wrong polarity could
damage the unit and void the warranty.
Notes:
1.)
For best performance and longer operating time, we recommend the use of
good quality alkaline battery.
2.)
The batteries need to be replaced when if the volume level becomes
significantly lower, if the sound is distorted during operation or the unit no
longer functions properly.
BATTERY WARNING
•
Be sure the batteries are installed correctly. Wrong polarity may damage the unit.
•
Use only the size and type of batteries specified.
•
Do not mix old and new batteries.
•
Do not mix alkaline, standard (carbon-zinc) or rechargeable (nickel-cadmium)
batteries.
•
If the unit is not to be used for an extended period of time, remove the batteries. Old
or leaking batteries can cause damage to the unit and may void the warranty.
•
Do not try to recharge batteries not intended to be recharged; they can overheat and
rupture. (Follow battery manufacturer’s directions).
•
Do not dispose of batteries in fire, batteries may leak or explode.
B. AC ADAPTOR OPERATION (AC ADAPTOR NOT INCLUDED)
1.
Plug the cord of the AC adaptor into the DC IN JACK (#13) of the SCR-75.
2.
Plug the AC adaptor into a household 120V/60Hz AC power outlet.
3.
The batteries will automatically disconnect when the AC adaptor is plugged into the
SCR-75 and the unit will operate using the AC adaptor power.
NOTE: Only use adaptor with an output voltage
rated at DC 3V
600mA with a
center positive plug.
