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 manufacturerís instructions to clean the contact surfaces.
•
Remember that a battery recharge takes approximately 3 1/2 hours.
•
Avoid removing and reinserting batteries while they are charging (charging status indicator is RED).
•
Remember that batteries discharge fastest during Talk and Page
operation. Avoid unnecessary communications.
•
Always use the On/Off switch to power off the headset before removing the battery.
Important Information about Rechargeable Batteries
Keep the following information in mind as you operate the system and as you establish operating procedures:
•
Each 3M™ Wireless Communication System Model XT-1 battery contains an internal
protective device to prevent unsafe discharge rates. But, as with any battery, avoid
shorting across the battery contacts with metal items. Never carry a battery in a pocket
or place it in a drawer where it can accidentally be shorted by keys, coins etc.
•
Have adequate charging capacity for the number of headsets in your system. One 3-slot battery charger
will handle up to three headsets. Use of more than three headsets requires a 6-slot battery charger.
•
Batteries perform best at moderate temperatures. Extremes of heat and cold reduce their performance.
•
An unused 3M™ Wireless Communication System Model XT-1 battery loses five percent of its
charge per week. Batteries that have not been used for several weeks should be recharged before use.
The four-character date code stamped on each 3M battery (wwyy) refers to the week
and the year the battery was manufactured. Batteries are generally usable for two years
beyond that date. Batteries used more often will need replacement sooner.
WARNING
Do not open, crush, expose to heat above 200 °F (93 °C) or incinerate the battery.
