In the REPEAT mode, you talk through the repeater, which increases the

radio's operating range. The transmit frequency is not the same as the receive

frequency.

The repeater talkaround feature is programmed to the three-position toggle

switch, one position on the switch will select the REPEAT mode, and another

position will select the DIRECT mode. See Table 2 located toward the rear of this

manual.

Note: Channel-slaved talkaround overrides the 3-position toggle switch if the

transmit and receive frequencies are the same.

Description

Smart PTT is a per-channel feature which increases the system manager's

control of radio operations. When smart PTT is enabled in your radio (using

Radio Service Software), the user will not be able to transmit on an active

channel. In addition, the monitor function can be disabled on channels

programmed with smart PTT. Three radio-wide variations of smart PTT are

available:

Transmit Inhibit on Busy Channel: With this feature enabled, you will be

inhibited from transmitting if any activity is detected on the channel.

Transmit Inhibit on Busy Channel with Wrong Squelch Code: With

this feature enabled, you will be inhibited from transmitting on an active

channel with a squelch code other than your own. If the squelch code is

the same as yours, the transmission will not be inhibited.

Quick-Key Override: This feature can work in conjunction with variation

one or two. With this feature enabled, you will be able to override the

transmit inhibit state by quick-keying (two PTT activations within one

second of each other) the radio.

Operation

Smart PTT radio operation is exactly the same as standard radio operation,

except that if you try to transmit (press PTT) on a busy Smart PTT channel, a

continuous alert tone is generated until the PTT is released; the transmission

is inhibited.

Repeater Talkaround

Repeater talkaround allows you to bypass the

repeater. This is referred to as the DIRECT mode,

when you talk portable-to-portable. The transmit

frequency is the same as the receive frequency (Tx

= Rx). The direct annunciator (

display when you are in direct communication with

another radio.

) appears on the
