Recharging starts and the “H” charging indicator flashes on the unit’s display. The indicator goes out when charging is complete.

3 When charging is complete, unplug the AC adaptor from the household AC outlet and DC IN jack.

≥Never mix dry cell and rechargeable batteries. ≥Turn the unit off before replacing the recharge-

able batteries.

Note!

≥Rechargeable batteries have a service life of approxi- mately 300 charge-discharge cycles. The batteries have reached the end of their operational life if they last for a noticeably shorter time after recharging, or if they cannot be recharged at all. Replace the batteries.

≥Recharging may only be performed when the unit is powered off.

≥The AC adaptor and rechargeable batteries may be- come warm while recharging is in progress. This is not a malfunction.

≥Leaving the AC adaptor connected can cause the bat- teries to go flat. After recharging the batteries and dis- connecting the AC adaptor from the AC power outlet, ensure you disconnect the AC adaptor from the unit’s [KDC IN 4.5 V] terminal.

Battery indicator

This indicator flashes when the batteries are almost out of power. Power is cut off completely a short while later. Rechargeable batteries: Recharge batteries.

Dry-cell batteries: Replace batteries with new ones.

Note!

≥The length of time the unit will continue to operate be- tween when the battery indicator starts flashing and when the power is cut off differs depending on the type of batteries used.

≥The battery indicator may not be displayed if recharge- able batteries other than those designated by Panasonic are used.

Using the car adaptor (not included)

Be sure to obtain the car adaptor (SH-CDC9), available as an optional accessory.

The car adaptor can be used to recharge the unit’s bat- teries while in the car.

CAUTION:

This function causes the unit to ignore short, accidental button presses. (The disc lid can still be opened and closed.)

The HOLD function prevents the following:

≥The unit is powered on accidentally when not in use, causing the batteries to run down.

≥A button is accidentally pressed during play, interrupt- ing the operation.

To use the HOLD function

Set [HOLD] to the HOLD position.

The unit and wired remote control have HOLD func- tions, each of which works independently.

“(” indication

When the main unit is in HOLD mode, pressing any but- ton causes the indication “(” to appear on the dis- play.

When the unit is powered off

The “(” indication appears only when [1/;] (main unit) is pressed.

Before operating the buttons

Be sure to move [HOLD] to release the unit from the HOLD mode.

Anti-Skip System

This system deals with skipping in a variety of ways:

≥The thinner and lighter construction makes the unit less susceptible to vibration.

≥An anti-skip mechanism prevents skipping caused when play speed changes due to swinging of the unit.

≥A recovery system immediately returns the laser pick- up to its original position if it is knocked off the track by a strong shock.

≥Anti-skip (max. 48 seconds) memory fills in interrup- tions caused by bumps and vibrations.

The anti-skip system works automatically while the system is on and cannot be canceled.

When bumps continue repeatedly

The elapsed playing time disappears and sound is inter- rupted.

S-XBS

Note!

≥While the system is on, the disc rotates at a higher rate than usual in collecting extra audio data. This could result in a slight increase in disc rotation noise.

≥The anti-skip memory compresses digital signals.
