Ericsson LBI-38823C Portable Radio User Manual


 
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.
Tones For Trunked Operation Only
Call Originate
EDACS - If programmed, a short tone is sounded whenever the
Push-To-Talk (PTT) button is keyed and the radio has acquired a

GE-MARC - If programmed, a three tone alert is sounded whenever
the Push-To-Talk (PTT) button is keyed and the radio has acquired a
channel. This tone indicates the user may proceed to talk.
