Plantronics CS50/Plantronics CS55:
The Plantronics CS55 and Plantronics CS50 headsets require a 20 minute charge for partial functionality and 3 hours for a complete charge. To charge these headsets, simply slide them into the charging base and be sure that the amber light (on the left side of the base) begins flashing. When the amber light becomes solid, the headset is fully charged.
If your headset does not turn on (no green light), then your battery has no charge.
Place your headset on the charging base, and look for the base’s amber light. If the amber light blinks, then your headset needs to charge. When the headset is fully charged, the amber light will become solid. If, after a full day, the amber light continues to blink, it may indicate a charging problem with the battery.
If your headset never fully charges, or if your fully charged headset gives less than 8 hours of talk time, then your Plantronics CS50/CS55 battery may need to be replaced. .
