2.2.2 Replacing the Batteries

CAUTION! Replace batteries only with the specified rechargeable batteries. The battery charges when the unit is off. Do not attempt to recharge non-rechargeable batteries.

If you need to replace the rechargeable batteries, use the recommended 3.0 Ahr NiMH batteries (part number 200-081). While the batteries can be recharged up to 600 times, it is best to replace them when they no longer provide acceptable performance. To replace the batteries, remove the rubber boot, open the panel located on the back of the PT878 unit, disconnect the batteries, and replace with new ones (see Figure 3 on page 11).
