Choosing Power Source

Installing Batteries (See fig. A)
Choosing Power Source

  1. Open the lid of the battery compartment at the rear of the unit.
  2. Install three R6 (size AA) batteries (not supplied) with correct polarity and then close the lid.
    "0:00" flashes on the display after you first install the batteries. To stop flashing, set the clock. (See "Setting the Clock".)

Battery Life

* Measured value by the standard of EIAJ
(Electronic Industries Association of Japan) The battery life may shorten depending on the operation of the unit.

Knowing when to replace the batteries
When the batteries become weak, the sound becomes weak and distorted. "" flashes on the display. When the batteries are completely exhausted, "" appears on the display and the power is turned off.
When "" appears, replace all the batteries with new ones.

To attach the battery compartment lid if it is accidentally detached (See Fig. B)
To attach the battery compartment lid

  1. Put in one side of the lid as illustrated.
  2. Push the other side to attach.

Note on replacing the batteries
Do not take more than 40 seconds to replace the batteries, otherwise the clock, standby settings and preset stations will be deleted from the memory.
Should that happen, reset the functions again. After the batteries are replaced, press POWER to turn the indication off.

Notes on batteries

  • Do not charge the dry batteries.
  • Do not carry the dry batteries with coins or other metallic objects. It can generate heat if the positive and negative terminals of the batteries are accidentally contacted by a metallic object.
  • When you are not going to use the unit for a long time, remove the batteries to avoid damage from battery leakage and corrosion.
  • Do not use different types of batteries at the same time.
  • When you replace the batteries, replace all with new ones.

Using House Current (See fig. C)
Using House Current
Connect the AC power adaptor (not supplied) to the DC IN 4.5 V jack firmly, and plug it into a wall outlet.

Notes on the AC power adaptor

  • When operating the unit with an external power source, do not remove the batteries. These batteries serve to backup settings stored to memory. Since batteries discharge in this case as well, we recommend changing them about once a year.
  • Before connecting and disconnecting the external power source plug, be sure to turn off the radio. Otherwise, "E" may be displayed. When this occurs, turn on the radio so that "E" disappears.
  • When operating the unit with the internal batteries, remove the AC power adaptor from the wall outlet and the DC IN 4.5 V jack. Make sure that the plug of the external power source is disconnected before operating the unit.
  • Use a commercially-available AC power adaptor* (rated output voltage/current: 4.5 V DC/700 mA). Do not use any other AC power adaptor.
  • Depending on the AC power adaptor, noise may be heard while using the unit. Refer to the operating instructions of the AC power adaptor.
    Polarity of the plug

    * The voltage of power supply is different depending on the country. Please buy an AC power adaptor in the country where the radio is to be used.

Setting the Clock
