Jensen MR-720 instruction manual Special Note, Power Source, Charging the Internal Batteries

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.
