The Power LED on the base unit does not turn on.

The power LED will only turn on when there is an active input signal. So, if you have your TV connected to the base unit, the Power LED will light up only when your TV is on and transmitting audio. This is to save on-standby power.

Does the RF900 work with other rechargeable batteries?

It actually does, but requires a little tinkering. This is a deliberate design choice as putting non-rechargeable batteries and then docking the headset to the base station will actually cause permanent damage to the RF900 when the base station attempts to ‘recharge’ the batteries. To prevent this, we have designed a special side contact. See the image below on how to convert a third-party rechargeable battery to suit the RF900 headset.
