#1 How do I use my Philips Voice Tracer audio recorder?
Connect the recorder to a computer using the USB cable and press the g button for 1 second or longer to start recording (LFH860/870/880 only). To record with an external microphone, connect the microphone to the microphone socket and follow the same procedure as for the built-in microphone.
Charge the battery The rechargeable battery Philips LFH9154 can be charged in the Voice Tracer. When the Voice Tracer is connected to a computer, the rechargeable battery is automatically charged. A complete recharge cycle takes about 2.5 hours.
