Chapter 6: Advanced Features
• Turn off the ignition through Ignition Sense Line.
The display shows Tx inhibit on. You hear a sequence of short, low-high tones to indicate
that transmission is inhibited.
Pressing PTT triggers the radio sounds a constant short, low-pitched tone (reject tone).
NOTE: The status of the Transmit Inhibit does not change after the radio powers up.
The softkey TxIn is created to ease the user of inhibition transmission besides relying solely
on Ignition Sense Line. Only if the Ignition Sense Line is on, the softkey TxIn works. If the
Ignition Sense Line is on, you can always turn on or off the Transmit Inhibition using the softkey
TxIn; but when the Ignition Sense Line is off, function of softkey TxIn is suspended, and the
Transmit Inhibition function is always off.
If PTT TX Inhibit is enabled, when using multi-control head with one active configuration, with the PTT
pressed on the active control head, any press on the programmable button of the other control head
which meant for that control head to be active control head causes an unstoppable long low-pitched
tone (Talk Prohibit Tone). The display shows Tx inhibit. This behavior can be stopped by pressing
PTT button again on the active control head

Disabling Transmit Inhibition

Procedure:
Perform one of the following actions:
• or to TxIn. Press the Menu Select button below TxIn.
• Turn on the ignition through Ignition Sense Line.
The display shows Tx inhibit off. You hear a sequence of short, high-low tone (Transmit

Universal Relay Controller

The Universal Relay Controller (URC) is a relay module that controls the patterns on the Light Bar
operation.
The URC receives logic level input signals configured by programmable logic controller (PLC), process
controllers, and indicators to switch on/off a series of output signals. The URC supports up to 25
customized patterns, each pattern is a combination of 10 relays in the URC.
The buttons or knobs that support URC are:
• P Button
• Keypad Buttons
URC also supports Action Consolidation feature to run the lightbar.
Consult a qualified radio technician for details on customizing different relay patterns using the
Customer Programming Software.

External Alarms (Horn and Lights)

Your service administrator may configure the control heads with external alarms (horn and lights) that
are activated when a Call Alert Page, Private Call, or Phone Call is received. The radio always powers
up with the horn and lights feature enabled.
