Convenient Functions
VOX Operation
The VOX system provides automatic transmit/receive switching based on
voice input. With the VOX system enabled, you do not need to press the PTT
switch in order to transmit. Optional VOX earpiece microphone (SSM-512B) is
also available.
VFO Split Mode
Two different frequencies, one for receive and another for transmit, may be
operated.
Tone Squelch feature
The tone squelch opens the speaker audio only when a signal containing the
specified CTCSS tone is received. By matching the tone frequency with the
partner station in advance, a quiet standby is possible.
Digital Code Squelch (DCS) feature
DCS (Digital Coded Squelch) function allows audio to be heard only when
signals containing the same DCS code are received.
New PAGER (EPCS) feature
This new feature allows calling specified stations only, by using a pager code
that combines two CTCSS tones. Even when the person who is called is not
near the transceiver, the information is displayed on the LCD indicating that a
call was received. When the call is received, the bell sounds. The transceiver
is automatically placed in transmit mode (for about 2.5 seconds) when called
by the other party, and notifies the other party that you are ready to communi-
cate.
