1. Remove the screws from
these two locations.
2. Remove the battery compart-
ment cover.
3. Insert batteries, taking care to
observe the correct polarity.
Removing the battery case
Although it is possible to replace the batteries without removing the
battery case, battery replacement will be easier if you remove the
battery case.
1. Remove the screws from these
two locations.
2. Remove the battery case.
* We recommend that you keep batteries installed in the unit even
though you’ll be powering it with the AC adaptor. That way, you’ll be
able to continue a performance even if the cord of the AC adaptor
gets accidently disconnected from the unit.
* To prevent malfunction and speaker damage, make sure to switch
off the KC-110’s power before you insert or replace its batteries, and
before connecting it to other devices.
* Take care that no metal object touches the contacts of the battery
case. This can short-circuit the batteries, causing the case to
overheat or burn.
About batteries
Batteries that can be used
The KC-110 uses eight AA alkaline or nickel-metal hydride batteries.
* Nickel-metal hydride batteries cannot be recharged by the KC-110
itself. You’ll need to use a commercially available battery manufac-
turer.
* When using nickel-metal hydride batteries, please be aware that the
battery life will normally shorten each time they are recharged.
Caution regarding batteries
• Insert the batteries as directed, taking care to observe the correct polarity (+/- orientation).
• Do not mix new and used batteries, or batteries of different types.
• Carefully read and observe the cautions and handling instructions that accompany the batteries.
When using nickel-metal hydride batteries, you must use the charger that is specified by the battery manufacturer.
• Remove the batteries if you won’t be using the unit for several months.
• If any electrolyte leaks from a battery, use a dry cloth to carefully wipe off any electrolyte that might be on the battery case, and then install new
batteries. Battery electrolyte that contacts your skin may cause a rash. Battery electrolyte is hazardous to your eyes; if any electrolyte gets into
your eyes, flush them immediately with water.
• Do not carry or store batteries together with metallic objects such as pens, necklaces, or hairpins.
