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 leading to either side. If the headphones are placed correctly, the charge indicator light illuminates.
4.Subsequent charging must be performed in about
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 to in varying degrees, and the battery’s capacity drops 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
If you are using NiMH or NiCd batteries, the batteries will charge when the headphones are powered with the AC power adapter. Do not power the headphones with the AC power adapter if you installed alkaline or other
