Pressing the ALP key switches the BHT to the alphabet entry mode. You can type in alphabet letters

You can switch between the numeric and alphabet entry modes also in user programs. For programming
the mode switching, refer to the "BHT-400-CE API Reference Manual" or "BHT-400-CE Class Library
Reference Manual."
