Standard conventional calls can be placed to other mobile units monitoring the selected 
channel. The proper coded Call Guard squelch tone or code or P25 NAC may need to be 
transmitted by your radio for them to receive your call (see Sections 5.4 and 5.15.3).

1 Turn power on and set the volume as described in Section 3.1. Select the channel 

programmed for the mobile you want to call (see Section 3.4.2).

2 Monitor the channel automatically or manually as described in Section 5.1.

3 Press the PTT switch and if the Busy Channel Lockout feature is programmed on the 

channel, the transmitter is automatically disabled if the channel is busy (see 
Section 5.3). Otherwise, busy and out-of-range conditions are not indicated and 
speaking can begin after monitoring the channel.

4 Press (and hold) the PTT switch to talk and release it to listen. When the call is finished, 

place the microphone back on-hook.

1 Select or scan the channel programmed for the call you want to receive (refer to 

Section 5.10 for more scanning information).

2 When the call is received, take the microphone off-hook and press the PTT switch to 

talk and release it to listen. If scanning, responses may occur on the priority, selected, or 
receive channel as described in Section 5.10.2.

3 When the call is finished, place the microphone back on-hook.

DTMF (Dual Tone Multi-Frequency) tones can be generated for ANI (Automatic Number 
Identification) and other purposes on conventional analog channels. One of the following 
options may be enabled on each channel:

Pre-Tx ANI - A preprogrammed ANI sequence is automatically sent each time the PTT 
switch is pressed.

Post-Tx ANI - A preprogrammed ANI sequence is automatically sent each time the 
PTT switch is released.
