Battery maintenance

Maximizing battery life

Avoid extreme ambient temperatures

Your device is designed to perform well in a wide range of ambient temperatures, with 62° to 72° F (16° to 22° C) as the ideal comfort zone. It’s especially important to avoid exposing your device to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity.

Store it half-charged when storing long term

If you want to store your device long term (e.g. summer breaks), two key factors will affect the overall health of your battery: the environmental temperature and the percentage of charge on the battery when it’s powered down for storage. Therefore, we recommend the following:

• Do not fully charge or discharge the battery – charge to around 50%.
• Power down the device.
• Store in a cool moist-free environment less than 90° F (32° C).
• Top up charge to 50% every 3 months.

During regular use

Do not run battery completely flat and do not leave product connected to charger when fully charged.

Does the pen(s) work with USB-C?

A USB-C to USB-A adapter is however required.

Can I upgrade the ExamReader firmware?

Starting 2018, ExamReader has been updated to support software upgrade. For more information, see ExamReader firmware upgrade.


The pen only reads gibberish / do not read at all

We are confident that reading/scanning performance of our products are very good.
To eliminate some reasons for bad scan result, please start using something with clear printed black tet on white background (e.g. a textbook).
Then confirm that:
  1. Scan Language is set to correct language.
  2. The device is set up for Left/Right Hand use – subject to how you use it. See this video for details.
  3. Confirm that scanning is made according to instructions in the above video. Note that is shall be rather straight up from the paper and moved straight at a steady speed.

Should the C-PEN still not recognise the text properly then please shoot a short video showing the failing scan process and submit a ticket to us on this site.
