3M™ Wireless Communication System, Model XT-1: Operating Instructions

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.
•
Remember that a battery recharge takes approximately 3 ½ 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 XT-1 Rechargeable Batteries

Keep the following information in mind as you operate the system and as you
establish operating procedures:
•
Each 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 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.
Do not open, crush, expose to heat above 200 °F or incinerate the battery.
