BATTERY INSTALLATION AND INFO (continued)
Charging the Rechargeable Batteries
Follow these steps to recharge the NiMH rechargeable batteries.
1. Connect the AC/DC main power adapter to the DC IN
power supply socket, located on the back of the recharging
cradle/transmitter.
2. Then, plug the adapter into an electrical outlet.
3. Place the headphones into recharging cradle/transmitter, with
the charge indicator facing to the front. Make sure the headphones
are placed in a completely vertical position, not leaning to either
side. If the headphones are placed correctly, the charge indicator
light illuminates.
4. Subsequent charging must be performed in about 15-17 hours.
NiMH Rechargeable Battery Memory Effect
When an NiMH rechargeable battery is first used, it is important to fully
charge it and then allow it to discharge three times in order to maximize
the battery’s storage capacity. When a battery is recharged before
it is completely discharged, it develops a memory that will limit the
amount of charge in the future. This reduces the battery’s storage
capacity for subsequent charges and so reduces the amount of time
your headphones can be used before recharging is necessary.
NiMH Natural Power Discharge
Due to their chemical design, all rechargeable batteries incur some
degree of natural discharge. This means they automatically lose their
charge in varying degrees, even when not in use. The size of this power
loss varies, depending on the battery’s type, size, design, internal
resistance and, most especially, the temperature. The higher the
temperature, the greater the power loss through natural discharge.
NiMH Battery Warning
1. To avoid risk of fire, explosion and injury, do not attempt to recharge
non-rechargeable batteries.
2. Respect the environment and the law. Before disposing of
rechargeable batteries, ask your retailer if they can be recycled and
whether or not the retailer collects rechargeable batteries
for recycling.
