Replacing Batteries
Replacing the Cordless Pen Batteries
The pens require two 393 silver oxide batteries. The average battery life is
200 hours.
To replace the batteries:
1 Unscrew the pen cap. Hold
the pen from the bottom and
gently slide off the pen cover
to expose the batteries.
2 Remove the old batteries by
turning the pen over and
gently tapping it, letting the
batteries fall into your other
hand.
Do not use ZINC AIR batteries as replacement batteries.
They will corrode the electronics of the pen.
When you replace the pen batteries, the pen will reset to the
default frequency. If you changed the frequency of the pen
before replacing the batteries, you will need to do so again after
replacing the batteries (see the Reducing Monitor Interference
section in Troubleshooting).
