Replacing the Cordless Pen Batteries
The pen requires 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.
3. Insert the new batteries as they
are shown in the figure above (+
towards pen tip).
4. Replace the pen cover and screw
the pen cap onto the pen.
NOTE: 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).
