External Accessories
The SP-3, SP-4 and SP-55 External Speakers are optional accessories which allow
the source of audio from the transceiver to be repositioned for optimum hearing.
Especially practical for the noisy mobile environment, each includes its own
swivel-type mounting bracket, and is available from your Yaesu dealer. Also
available to enhance safety and mobile operating convenience are the YH-I Headset
with miniature boom microphone, and the full size MF-1A3B boom microphone
with flexible arm (both of which use the SB-10 PTT switch).
