TECH-DEV - Error code 128

My tCheck device is reporting an error code 128 and cannot proceed.

Error code 128 is a power-on self-test (POST) failure that says the internal light sources are not strong enough. There are several potential causes for this.  Please try the following:

• Replace with fresh/brand new premium batteries.  We recommend Energizer Max.
• Ensure the tray is not inside the device when it is powered up.
• Nothing has spilled inside the device/tray slot.

If Error Code 128 persists, please contact Customer Support and provide your order number.
