Battery preparations

Hand crank battery charging

The unit can operate on the power from the built-in rechargeable batteries 
that you have charged by cranking the handle for charging.
The rechargeable batteries built into the unit are charged irrespective of 
whether the battery selector switch is in [RECHARGEABLE BATTERY] or 
[DRY BATTERY] position.

1

Pull out the handle

2

Crank the handle to 

charge the batteries

CHARGE lamp

Handle

 

• Crank in either direction. The CHARGE lamp is lit.

 

• It is recommended to crank at a rate of 2 revolutions per second 

(120 revolutions per minute). (For battery runtime, see page 8.)
The power generation amount depends on your speed while cranking 
the handle. Cranking at a slower speed than the above may keep the 
CHARGE lamp lit, but results in a shorter battery runtime because of a 
smaller power generation amount.

Notice

 

• Retract the FM rod antenna in place before cranking the handle.

 

• Do not crank the handle too fast. Doing so can cause your wrist to hurt or the unit to 

malfunction.

 

• Prolonged, continuous cranking operation may cause the unit to malfunction, so 

when you keep operating the handle for a prolonged time, have about 1 minute of 
pause for every 2 or 3 minutes of operation.

 

If the rechargeable battery is not used for a long time, the rechargeable battery 
performance may degrade. Charge the batteries once every 6 months by 
cranking at a rate of about 120 revolutions per minute for 2 to 3 minutes, and 
make sure the unit is entirely operational.

Note

 

• With the battery selector switch in the [RECHARGEABLE BATTERY] position, when 

the unit runs out of the rechargeable batteries, “

” starts blinking.

Crank the handle to charge them.

 

• The rechargeable batteries can be charged during radio reception, but noise may 

interfere with radio broadcasting. So it is recommended to keep the unit turned off 
while charging them.

Use of dry-cell batteries 

(sold separately)

1

Pull out the handle 

and open the battery 

box lid

2

Put 3 LR03 (AAA 

size) alkaline dry-cell 

batteries in the box

  Insert the dry-cell batteries 

negative end first

Notice

 

• Keep the batteries out of reach of children to prevent swallowing.

Note

 

• Due to their extremely short battery runtime, the use of manganese dry-cell batteries 

is discouraged.

 

• With the battery selector switch in the [DRY BATTERY] position, when the unit runs 

out of the dry-cell batteries, “

” starts blinking.

When replacing the dry-cell batteries, replace all of the three with new ones.

 

• It is advisable to turn the unit off before replacing the dry-cell batteries.

 

• If the unit will not be used for a long time, remove the dry-cell batteries from it.

selection is started, and it is stopped as the 
radio is tuned to the first station to be received.

 

• Depending on the particular reception status, 

you may not be able to use automatic station 
selection. When automatic station selection is not 
stopped, press either TUNING [

] or [+] to quit.

The step is factory-set to 0.2 MHz, but you can change it to 
receive broadcasts allocated to 0.1 MHz steps.

1. Press [FM/AM] to “FM” mode.
2. Press and hold [FM/AM].

SIREN

An audible alarm is generated.

 

LIGHT

The light turns on.

 

• To stop an audible alarm or turn off the light, set the 

switch to “OFF”.

Note

 

• SIREN or LIGHT can be used irrespective of whether the radio is powered on / off.

 

• The audible alarm starts out soft and then becomes louder.

 

• The volume of the audible alarm or the brightness of the light is unadjustable.

 

• The audible alarm volume or the light brightness may vary depending on the type of 

the batteries used or the remaining battery level.

 

• Some surrounding conditions may keep you from hearing the audible alarm.

Personal equipment like a mobile phone can be charged by connecting via a 
charging cable to the unit. It is charged only when the handle is being cranked.

1

Connect a charging cable (not supplied) between 

your smart-phone or mobile phone and the unit

Use an appropriate adapter 
(commercial) for your 
model as necessary.

2

Crank the handle to charge the batteries

 

• The charge lamp is lit while charging is in progress. 

Crank at a speed that allows the lamp to stay lit. 
(The built-in rechargeable batteries are also charged)

 

• Crank in either direction.

 

• It can be charged even when the battery selector 

switch is either in [RECHARGEABLE BATTERY] or 
[DRY BATTERY] position.

Mobile phone charging

Guideline for the runtime that a fully-charged mobile phone battery 
provides for

(For smart-phone measured by Panasonic and charged by cranking at a 
rate of about 120 revolutions per minute for 1 minute

)

Continuous standby time:

 Approx. 1 h. and 50 min.

Continuous talk time:

 Approx. 2 min.

   If your mobile phone has run out of the battery to such an extent that it cannot be 

even powered on, it requires a longer recharging time.

Notice

 

• Close the mobile phone charging jack lid when you are not using the mobile phone 

charging jack.

 

• Do not apply any external voltage to the mobile phone charging jack. Otherwise, it 

may cause a malfunction.

 

• When the handle is cranked at a rate of less than 120 revolutions per minute, a 

warning message may be displayed on the mobile phone connected to the unit 
because of an insufficient amount of power generation.
In such case, temporarily stop rotating the handle and then try to crank it at a rate of 
120 revolutions per minute.

 

• Charging status displayed on some smart-phones or mobile phones may be 

switched between the ON / OFF states repeatedly. 
In such case, crank the handle at a rate of more than 120 revolutions per minute.

Note

 

• Even if the dry-cell battery has a certain amount of its power remaining, it cannot be 

used to recharge a mobile phone.

 

• The rechargeable batteries can be charged during radio reception, but noise may 

interfere with radio broadcasting. So it is recommended to keep the unit turned off 
while charging them.

 

• Note that some mobile phone models cannot be recharged.

Operating error 

prevention (HOLD)

OFF

ON

Sliding HOLD to the [   ] side disables the [

], 

[VOL], [FM/AM] and [TUNING] buttons.
The function prevents such an operation error as the 
one that could occur while the unit is put on charge. 
In addition, while the unit is carried in a bag with you, 
it blocks the unit from powering up even when the 
button is inadvertently pressed. (Display: 

)

 

• To deactivate HOLD, slide the switch left back in “OFF”.

Note

 

• SIREN or LIGHT can be used even while HOLD is on.

 

• The unit or a mobile phone can be charged with a hand crank even during HOLD in use.
