Proper operation of this radio under normal conditions results in user exposure to RF energy below the Occupational Safety and Health Act and Federal Communication Commission limits. Mandatory Safety Instructions to Installers and Users: This radio is NOT approved for use by the general population in an uncontrolled environment. This radio is restricted to occupational use and work related operations only. [. . . ] An amber TX/Busy indicator means that the channel is busy, but the correct CTCSS or DCS signaling is not present. CTCSS/DCS allows multiple users to share the same frequency. However CTCSS/DCS is only useful to avoid disturbing other users with messages not related to them. If more than one radio is transmitting at the same time, this will cause interference. Do not transmit if the TX/Busy indicator is illuminated green or amber. Wait until the channel is clear before transmitting. 2-tone Operation 2-tone signaling allows individual or group calls to be made to your radio. The radio may have been programmed to mute all 12 © 2007, Midland Radio Corporation http://www. midlandradio. com OlympianTM Series Mobile Radio User's Guide receive signals until a 2-tone signal has been decoded. When the programmed 2-tone signal is decoded, the TX/Busy indicator will blink green, a beep sequence may sound, and subsequent receive audio will be heard over the speaker. The radio may be programmed to mute the speaker again after a programmed time, or you may press and hold the programmed Call Reset function button to mute the radio until it receives a new call. Consult your dealer or communications coordinator for further details on how your radio has been programmed for 2-tone operation. 2-tone signaling allows users to receive only calls intended for them. However, more than one radio transmitting at a time will still cause interference. Do not transmit if the TX/Busy indicator is illuminated green or amber. Wait until the channel is clear before transmitting. Before transmitting, the FCC requires you monitor the channel to make sure it is clear. Transmitting while someone else is transmitting will create interference and disrupt both conversations. Follow these steps to transmit to other radios. 1. Monitor the channel by pressing the programmed function button. Depending on programming the monitor button may disable 2-tone, CTCSS, DCS or noise squelch to allow you to check for channel activity. Channel activity is also indicated by the Tx/Busy indicator. If the channel is clear, press and hold the push to talk (PTT) switch on the side of the microphone. The TX/Busy indicator will glow red while the radio is transmitting. Hold the microphone approximately 2 inches from your mouth and speak across the face of the microphone in a clear, normal voice. 13 2. 3. 4. © 2007, Midland Radio Corporation http://www. midlandradio. com OlympianTM Series Mobile Radio User's Guide 5.
