Midland Radio Corporation subscribes to the same safety standard for the use of its products. Proper operation of this radio will result in user exposure far below the Occupational Safety and Health Act (OSHA) and FCC limits. DO NOT transmit for more than 50% of total use time (50% duty cycle). [. . . ] After the call has been acknowledged, by pressing PTT for example, the status LED will change to steady green until the radio is muted. The transceiver may be programmed to mute after a programmed time, or you may press and hold the upper function button for two seconds 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 or selective call operation. ! 2-tone and selective call 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 status LED is illuminated. Wait until the channel is clear before transmitting. Monitoring the channel The upper function button is used to activate the monitor function. The radio's monitor function can be programmed per channel and may operate differently on different channels. It may also be disabled on some channels. The following paragraph details the basic monitor function, but consult your dealer or communications coordinator if you are unsure how the monitor function operates. The monitor function may be programmed to disable squelch, CTCSS/DCS signaling, 2-tone/selective call signaling or some combination of these. To temporarily activate the monitor function, briefly press the upper function button. If the button is 18 © 2005, Midland Radio Corporation SP-400 Series User's Guide released within two seconds the monitor function will deactivate when released. If the upper function button is held pressed for more than two seconds the monitor function will latch on. Press and release the upper function button again to deactivate the latched monitor function. When the monitor function is activated a high pitched beep will sound and the status LED will light amber. When the monitor function is turned off a low pitched beep will sound and the status LED will turn off. The upper function button is also used to mute the radio after a 2-tone or selective call has ended. Press and hold the upper function button for more than two seconds to mute the radio until the next 2-tone or selective call. Transmitting to other radios Follow these steps to transmit on your radio: 1. Make sure that the channel is not busy (transmitting while another radio is transmitting will only create interference, please wait for the channel to clear). Talk in a normal voice with the microphone approximately 24 inches (5-10 cm) from your mouth. When finished speaking, release the PTT button.
