Battery installation

1Remove the battery cover.

2Insert the batteries according to the direction indicated in the battery compartment.

When inserting or removing the batteries, push them towards the battery terminals.

3Replace the cover.

Precautions for battery use:

Replace all old batteries with new ones at the same time.

Do not mix old and new batteries.

Remove the batteries if the unit will not be used for long periods of time. This will prevent potential damage due to battery leak- age.

Caution:

Do not use rechargeable batteries (nickel-cadmium battery, etc.).

Installing the batteries incorrectly may cause the unit to malfunc- tion.

Notes concerning use:

Replace the batteries if the operating distance is reduced or if the operation becomes erratic. Purchase 2 "AAA" size batteries (UM- 4, R03, HP-16 or similar).

Periodically clean the transmitter on the remote control and the sensor on the unit with a soft cloth.

Exposing the sensor on the unit to strong light may interfere with operation. Change the lighting or the direction of the unit.

Keep the remote control away from moisture, heat, shock, and vibrations.

Troubleshooting

If trouble occurs

When this product is subjected to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction.

If such a problem occurs, do the following:

1Set the unit to the stand-by mode and turn the power on again.

2If the unit is not restored in the previous operation, unplug and plug in the unit, and then turn the power on.

Note:

If neither operation above restores the unit, clear all the memory by resetting it.

Clearing all the memory (reset)

1Press the ON/STAND-BY button to enter the power stand-by mode.

2Unplug the AC power lead from the AC INPUT socket on the unit.

3Whilst pressing down the MEMORY/SET button and the but- ton, plug the AC power lead into the AC INPUT socket on the unit.

AC INPUT

Caution:

This operation will erase all data stored in memory including clock, timer settings, tuner preset, and CD programme.

After the above operation, interval span setting for AM will be returned to 9 kHz (50 kHz for FM) automatically.
