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.

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.

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.
