"SP" and the GRP (Group) field will display the last accessed call
number from the preprogrammed Special Call selection or will be
blank if no Special Calls are programmed for this area. If the radio was
put into Special Call mode the "S" and "PC" icons will be illuminated
and if the radio was put into Conference Call mode the icons will be
off.
2.
Enter the telephone number to be called. The first digit entered will
cause the System field and the 10’s digit in the Group field to blank.
The last digit entered will always be displayed in the 1’s digit of the
Group field. Any previously entered digits will scroll left. Only four
characters will be visible at a time with the leading character scrolling
off the display upon each new key entry.
3.
Complete the telephone entry by pressing the * key. The * key indicates
the digits are for an interconnect call. This will not be displayed but a
tone will sound.
4.
Press and release the PTT bar to initiate the call. The radio performs
the necessary signalling required to obtain a working channel. When
the signalling is successfully completed the "BSY" flag lights and the
proper DTMF tones will be sent and heard at the speaker.
The radio is out of range or the radio is inoperative when the signalling
is unsuccessful, the "NO" and "SV" indicators are illuminated and a
sequence of five beeps are heard at the speaker. Any subsequent
attempt to initiate a call within the next 20 seconds will be ignored. The
radio can be cleared from this mode by double clicking the SHFT/CLR
button.
All channels are busy when the signalling is unsuccessful and a one
second low frequency tone is heard at the speaker. The call will not
be retried automatically.
5.
To recall the last interconnect number entered manually from the
key pad, press and hold the SHFT/CLR button and then press
the RCL key.
