Using Your Headset - Motorola HT820 Manual

Using Your Headset

Charging Your Headset
First-Time Use-Before you can use your headset, you need to charge its self-contained battery
for two hours.
Recharging-When you hear five rapid high tones through the headset speaker, repeated at 20-
second intervals, the headset battery needs to be recharged.
Over time, batteries gradually wear down and require longer charging times. This is normal.
The more you talk on the phone with the headset, the less standby time your battery has.
The rechargeable batteries that power this product must be disposed of
properly and may need to be recycled. Contact your local recycling center
for proper disposal methods. Never dispose of batteries in a fire because
they may explode.
