Making Sure Batteries are Ready for Use
Follow these tips to make sure batteries are always ready for use:
•
Have an extra battery for each headset. This helps ensure that a fully
charged battery is always available.
•
Recharge a low battery as soon as it is removed from the headset.
When a battery is low, repeat messages are heard in the headset for 2
minutes, and then the headset shuts off.
•
Keep the battery and charger contacts clean. Use a cotton swab and
approved cleaner in accordance with manufacturer’s instructions to
clean the contact surfaces.
