SPECIAL NOTE
To prevent any scratching or damage to your furniture, we strongly recommend
that you purchase small self-adhesive felt pads, available at hardware stores
and home improvement centers everywhere, and apply these pads to the
bottom of the unit before you place the product on any fine wooden furniture.
POWER SOURCE
This unit operates using DYNAMO power (manual charge by cranking), on
optional battery power (3 x “AA” (UM-3) batteries–not included) or with an AC
adaptor (not included). The specification of the AC adaptor is: 6V DC 200mA with
center positive “+” plug.
A. “DYNAMO”
POWER
OPERATION
1. A DC 3.6V rechargeable battery is included with MR-720. When first time
using the unit, open the battery compartment and plug the rechargeable
battery into the socket as shown.
2. Replace the Battery Door.
3. Set the POWER SOURCE Switch to the “PWR OFF” position.
4. Lift the Crank Handle (#8) outward until it is fully extended. Rotate the Crank as
shown below. The CHARGING Indicator (#3) will light.
5. Continue turning the Crank for 3 minutes, about 2 turns per second, to achieve
approximately 10 minutes of power (Radio reception only).
Note: The frequency reading will disappear from the LCD in 2 to 3 minutes after
radio reception mode. This phenomenon is normal. The clock will resume once the
POWER SOURCE SWITCH has returned to “POWER OFF”.
B. BATTERY
OPERATION
(Optional)
1. Remove the Battery Door on the back of the radio.
2. Following the polarity diagram shown in the battery compartment, insert 3 ‘AA'
(UM-3) batteries (Not included) and replace the battery door.
3. When batteries were installed, the power of the build-in rechargeable battery
pack will be cut off after setting the POWER SOURCE Switch (#7) to
(DRY CELL Battery) position.
IMPORTANT: Be sure that the batteries are installed correctly. Wrong polarity may
damage the unit.
BATTERY PRECAUTIONS
i.
Use only the size and type of battery specified.
ii. Do not mix old and new batteries.
iii. Do not mix alkaline, standard (carbon-zinc) or rechargeable (nickel-cadmium)
batteries.
iv. If the unit is not used for an extended period of time, remove the batteries. Old
or leaking batteries can cause damage to the unit.
v. Do not dispose of batteries to fire, batteries may explode or leak.
C. AC ADAPTOR OPERATION (Optional)
This unit may also be used with an AC adapter (not included). When the AC
adapter is connected to the DC JACK (#24), the batteries are automatically
disconnected. Please make sure to use an AC adapter with a rating of 6V DC, 200
mA with the following center positive (+) polarity.
If you are using a universal adapter with an output polarity switch or polarized
plugs, be sure to set the center plug polarity to “+”.
Note: The CHARGE Indicator will light once the AC Adaptor is plugged into the AC
outlet regardless of the setting of the POWER SOURCE SWITCH (#7).
CHARGING THE INTERNAL BATTERIES
This Self-Powered Crank Radio contains a rechargeable Lithium Ion (Li-ion)
battery pack that can be fully charged in approximately 12 hours with an
external adaptor. After fully charged the unit will hold approximately 1 hour or
more of power (Radio reception only).
Note: Rechargeable batteries should be recharged:
i.
When they are used for the first time,
ii. They are low in power.
iii. They have not been used for a long period of time (over 60 days).
IMPORTANT: ONLY USE THE OPTIONAL AC ADAPTOR FOR CHARGING.
