Ericsson LBI-38823C Alert Tones, Standard Tones Power-Up, Low Battery, Carrier Control Timer

ALERT TONES

The Dual Format PCS™ radio generates a number of alert tones to indicate various events. The following section describes the alert tones for the Dual Format PCS™ radio.

Standard Tones

Power-Up

If programmed, a tone will sound on power-up after the radio passes the self-test.

Low Battery

A low pitch tone will sound every 130 seconds when the battery is low and needs charging.

Carrier Control Timer

The Carrier Control Timer (CCT) alert is a pulsed tone signal that sounds whenever the PTT button is continuously pressed for a prepro- grammed length of time. After nine seconds of pulsing the transmitter shuts down and communications is interrupted. To maintain communications, release and re-key the PTT switch. This resets the timer and turns the transmitter back on. The CCT is a built-in precaution against inadvertent use of the system.
