Disposing of Batteries
To help protect the environment and conform to regulations, G5 rechargeable batteries must be returned to 3M at the end of their useful life. Contact your 3M representative for additional instructions.
Making Sure Batteries are Ready for Use
Follow these tips to make sure batteries are always ready for use:
∙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 till the battery’s State of Charge (SoC) dips below the critical threshold at which point 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.
∙Remember that a battery recharge takes approximately 3 ½ hours.
∙Remember that batteries discharge fastest during Talk and Page operation. Avoid unnecessary communications.
Important Information about Rechargeable Batteries
Keep the following information in mind as you operate the system and as you establish operating procedures:
∙Each G5 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.
∙Batteries perform best at moderate temperatures. Extremes of heat and cold reduce their performance.
∙An unused G5 battery loses five percent of its charge per week. Batteries that have not been used for several weeks should be recharged before use.
Each battery has a USE BY label followed by a six character code. The first 2 characters refer to the month and the next four characters refer to the year. Once the calendar date is past the Use By date of the battery, you should replace that battery. 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.
