•

•
Avoid removing and reinserting batteries while they are charging
(charging status indicator is RED).

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 55ºC/130ºF or incinerate the battery.
