The amount of time the tester will stay in the active mode without pushing a key is controlled by the Power-Down Timeout setting.
Care & Maintenance 3M™ Dynatel™ Advanced Modular System 965AMS AC Charger Use the AC charger to charge the NiMH battery pack. Plug the AC cord into the AC charger and into a power outlet. Plug the DC cord into 965AMS tester. Make sure that the key on the plug fits properly into the slot in the connector. The AC charger is meant for charging the NiMH battery pack only. Charging efficiency is best with a temperature between 50°F (10°C) and 86° F (30°C).
3M™ Dynatel™ Advanced Modular System 965AMS Care & Maintenance Level of Charge The battery icon in the upper right of all screens indicates the battery charge. Four black bars in the icon indicate full charge. Zero black bars indicate the battery pack is very low and should be charged immediately. A warning screen appears when there are only five minutes charge left.
Care & Maintenance 3M™ Dynatel™ Advanced Modular System 965AMS Battery Pack The 965AMS tester uses a Nickel Metal Hydride (NiMH) battery pack. Typical life of battery pack is two years. To change the battery pack: 1. Power down the unit. 2. Place the unit upside down on a soft surface. Loosen the 5 screws. 3. Remove the battery cover. 4. Unplug the battery connector.
3M™ Dynatel™ Advanced Modular System 965AMS Care & Maintenance Battery Pack 5. Plug in the new battery connector. 6. Place the battery in the compartment. 7. Replace the cover. 8. Tighten the screws. Caution: Battery may explode, leak or catch fire if exposed to high temperatures or fire. Recycle or dispose of properly. To prevent injuries or burns, do not allow metal objects to contact or short circuit the battery terminals. Note: NiMH batteries should be recycled if disposal services are available.
Care & Maintenance 3M™ Dynatel™ Advanced Modular System 965AMS Battery Holder The plastic battery holder that comes with the unit uses six “AA” alkaline batteries (alkaline batteries are not included). Use alkaline batteries only when the NiMH battery pack is discharged and the AC adapter is not available. Typical lifetime of the alkaline battery pack is twenty hours of normal use (less if you use the backlight frequently, use the optional /SA or /ADSL features heavily, or work in very cold weather).
