Motorola III LED Indications, Time-Out Timer, Conventional or Trunked Radio Operation

14 Getting Started (cont.)

LED Indications

The indicator LED on top of the radio indicates radio operating conditions:

A.With PTT switch pressed (radio transmitting)

•Continuous red LED—normal transmission

•LED unlit—radio is not transmitting

•Blinking red light—Low battery (conventional radio only feature; programmable from the RSS)

B.With PTT switch released (radio receiving)

•Blinking red light—Mode busy (conventional modes only)

•Blinking green light—Receipt of a telephone call, Private Conversation call, or Call Alert page

Time-Out Timer

The time-out timer feature limits the amount of time that you can continuously transmit on a mode. If you hold down the PTT switch longer than the allotted time:

•A pre-alert warning tone will be generated four seconds before termination of your transmission to warn you that your conversation is about to be cut off.

•Four seconds later your transmission is terminated and an alert tone is emitted until the PTT is released.

Conventional or Trunked Radio Operation

Your MTS 2000 radio is capable of both conventional and trunked operation:

•Conventional Operation – During conventional operation, your MTS 2000 radio performs like a conventional two-way radio. That is, you must monitor the selected mode before transmitting (by checking the LED for mode busy [blinks red when busy] and listening for the “mode busy” tone, or pressing the monitor button) to ensure that you are observing standard two-way radio transmission protocol by not “talking over” someone who is already transmitting.

•Trunked Operation – During trunked operation, your MTS 2000 radio offers a number of advantages, including fast system access, enhanced privacy, and ease of operation. In a trunked system, there is no need for you to monitor a mode before transmitting.
