Cautions for use
• Set the variable L (between pins 17 and 18) of RFVCO so that the RF output frequency becomes 67.25MHz when 2.7V
is applied to V21 (pin21) in the US4ch mode for the US specifications, 97.25MHz when 2.6V is applied to V21 (pin21)
in the JPN2ch mode for the JPN specifications, and 211.25MHz when 2.5V is applied to V21 (pin21) in the TWN13ch
mode for the TWN specifications.
• Please observe Radio Law in each country when you use this product.
