BASIC OPERATION

BASIC MANUAL

 

Smart-Ring operation

This function can judge whether the other 

station is within range or out of range. A 

transceiver that receives a Smart-Ring call 

from another transceiver sounds the Ringer 

melody. Also, the called transceiver sends 

an acknowledgment signal back to calling 

transceiver.
The called transceivers automatically send 

an answer back call to your transceiver.

1.   Push [S-Ring/C-Ring] to make a 

Smart-Ring call.

 •The “

” icon is displayed while 

[S-Ring/C-Ring] is held down.

 •When an answer back call is received, 

the transceiver sounds the Ringer 

melody. 

When no answer back call is received, 

the transceiver sounds three short 

failure beeps.

2.   Push any key to stop the Ringer 

melody.

3.   Push [PTT] to transmit, if necessary.

NOTE: 

 •To use this function, the operating 

channel and CTCSS tone must be the 

same on all of your group’s transceivers.

 •This function can be operated for 

channels which CTCSS tone is set for.
