radio. 
15.4.1.5 Multiple Radio and Data Operation
Only the master radio supports mobile data operation. 
15.5  MACRO KEY OPERATION Macro key operation permits the user to accomplish a series of keystrokes with a single "macro" keystroke. 
Up to ten (10) macro keys can be defined, each capable of executing up to twenty (20) keystrokes, to any 
pushbutton input (i.e., keypad keys, buttons, etc.). Each macro key can be pre-programmed to activate 
when pressed or when released. 
A macro key can also be pre-programmed to change the keystroke sequence the next time the macro key is 
activated. 
For detail operation and assignment of macro keys, contact your communications supervisor or 
administrator. 
15.6  INTERCONNECT CALL (SYSTEM MODEL ONLY) To send a manually entered telephone interconnect call: 
1.   Select a channel in the radio system that has telephone interconnect capability. The radio should 
be programmed for DTMF operation on this channel. 
2.   Press the k button to toggle the keypad to the DTMF function (secondary function). 
3.  Press and hold PTT to key the transmitter. While h olding the PTT, press the * or # key (as 
required by the radio system to obtain a telephone line). The radio will transmit the selected tone. 
4.   Release the PTT and listen for a dial tone. When the dial tone is heard, press and hold the PTT 
while entering the desired telephone number. As each digit is entered and transmitted, the DTMF 
side tone will be heard from the speaker, if programmed to do so through ProGrammer. 
5.   After all the digits have been entered and transmitted, release the PTT. 
6.   When the call is answered, press the PTT and speak directly into the microphone. Release the 
PTT immediately to receive a reply. 
7.   When the call is finished, press and hold PTT and then press the * or # key (as required by radio 
system) to terminate the interconnect call. Release the PTT. 
8.   To return to the primary function of the keypad, press k. To continue with another 
interconnect call, repeat steps 3 through 8.
