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 b attery 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 X T-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/130ºFor incinerate the battery.
