* Dual IF design, value and IF / down mode can be preset separately.
* Using LCD0802 LCD display, can display up to seven digits, zero frequency
value is invalid automatic blanking.
* Anti-reverse power supply design, low-power battery scheme.
* Two-button control, a good man-machine interface.
* The settings are automatically saved in the EEPROM, the next boot directlycall.

中频切换两个中频的切换由编程接口 ICSP 第④脚的电平来实现，第④脚置高电平或悬空时使用第一中频，第④脚置低电平时使用第二中频。两个中频是独立的，中频值和加减模式可分别预置，互不干扰。第④脚置高电平或悬空时可预置第一中频，第④脚置低电平可预置第二中频。出厂时第④脚置悬空默认使用第一中频，中频值为零，加/减模式为减。在实际应用中，编程接口 ICSP 第④脚与第③脚（GND）用一条 2P 的杜邦线引出（下图红圈位置），使用开关或单片机控制编程接
