功能

• You can also use the remote control function on models that support the 8-pin connector.
• This function can be used with most FM units with the DR part number, but the sound quality may change slightly with older models, and you may need to adjust the microphone gain.
• The remote control works only with supported models.
• DTMF sounds, such as WIRES, that are required when accessing VOIP communications can be sent. (The pipopa sound cannot be monitored only with the microphone.)
• With a backlight, the design is easy to operate even at night.
