"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.
NOTE
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.
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.
