[. . . ] User's Guide SP-400 Series Portable 4/16 Channel VHF-FM Portable Transceiver 4/16 Channel UHF-FM Portable Transceiver www. midlandradio. com SP-400 Series User's Guide FCC RF EXPOSURE COMPLIANCE REQUIREMENTS FOR OCCUPATIONAL USE ONLY The Federal Communications Commission (FCC), within its action in General Docket 93-62, November 7, 1997, has adopted a safety standard for human exposure to Radio Frequency (RF) electromagnetic energy emitted by FCC regulated equipment. 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. Transmitting more than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. [. . . ] An on frequency signal with the correct CTCSS or DCS signaling will be indicated by a steady amber status LED. If the latched monitor function has been engaged the status LED will also light steady amber. ! 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. Wait until the channel is clear before transmitting. © 2005, Midland Radio Corporation 17 SP-400 Series User's Guide 2-tone/selective call operation 2-tone or selective call signaling allows individual or group calls to be made to your radio. The radio may have been programmed to mute all receive signals until a 2-tone or selective call signal has been decoded. When the programmed 2-tone or selective call signal is decoded, the status LED will blink green, a ring tone may sound, and subsequent receive audio will be heard over the speaker. 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. 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. 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.
