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. [. . . ] In addition to the signal having to exceed the squelch threshold level, the received signal must also have the correct CTCSS or DCS tone or code before the audio will be passed to the speaker. CTCSS or DCS signaling allows multiple users on the same frequency to hear only signals which have their correct CTCSS tone or DCS code. An on frequency signal with the correct CTCSS or DCS signaling will be indicated by a steady green TX/Busy indicator. An amber TX/Busy indicator means that the channel is busy, but the correct CTCSS or DCS signaling is not present. 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. 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. 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. If the channel is clear, press and hold the push to talk (PTT) switch on the side of the microphone. 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. Keep the PTT switch pressed until you have finished speaking. Press PTT before you start talking and release PTT after you have finished speaking. Your radio doesn't allow you to talk and receive simultaneously, so keep your transmission short. [. . . ] This allows the radio to communicate directly with other radios, which normally communicate through a repeater system. TX Power Press and release this button to toggle the transmit power between the high and low power levels. 22 © 2007, Midland Radio Corporation http://www. midlandradio. com OlympianTM Series Mobile Radio User's Guide Key Assignment Notes A B C D Message Display Quick Reference Error Codes Display NO EEP PLL ERR EEP ERR HI TEMP CLN ERR DAT ERR LOW BAT HIGH BAT PASS ERR TYPE ERR SET ERR Description No response from EEPROM PLL unlock EEPROM data error Radio high temperature Cloning error Serial communication error Low battery voltage High battery voltage Password entry error Incorrect radio model Radio mode error © 2007, Midland Radio Corporation http://www. midlandradio. com 23 OlympianTM Series Mobile Radio User's Guide Function Codes Display Description IND CALL GRP CALL ALL CALL KIL CALL RES CALL ANI CALL NO FUNC NSC ON NSC OFF TA ON TA OFF SQL 0-15 LOCK ON LOCK OFF EMER PA ON PA OFF ALRT ON ALRT OFF MCH1-2 MEMCH1-2 CALL1-4 2TONE HKAL ON HKAL OFF TUNE PROG PASS Individual call Group call All call Kill call Resurrection call ANI start call No function assigned to key Channel restored to scan list Channel temporarily removed from scan list Talk around on Talk around off Current channel squelch level Key lock on Key lock off Emergency function activated Public address on Public address off Call alert (horn) enabled Call alert (horn) disabled Switch to memory channel Memorize current channel to memory slot DTMF call encode 2-tone call encode Hook alert on Hook alert off Tuning mode Programming mode Password prompt 24 © 2007, Midland Radio Corporation http://www. midlandradio. com OlympianTM Series Mobile Radio User's Guide Specifications General specifications MO-7008/7128 (70W) VHF Frequency range FCC ID number FCC type acceptance Maximum number of channels Maximum number of banks Channel spacing Channel stepping CTCSS/DCS per channel Input voltage MIL spec Size (HxWxD) Weight EIA/TIA-603 receiver specs Frequency stability 12 dB SINAD sensitivity Selectivity Intermodulation rejection Spurious rejection Acceptable radio freq displacement Squelch sensitivity Audio response Audio output RF input impedance EIA/TIA-603 transmitter specs RF power output Frequency stability Modulation type Adjacent channel emissions Spurious emissions FM hum & noise Audio response Audio distortion RF output impedance 50 Watts or 5 Watts 70 Watts or 10 Watts ±2. 5 ppm (-30° to +60° C) 16KOF3E/11KOF3E 70 dB WB/60 dB NB 70 dB 45 dB WB/40 dB NB per EIA/TIA-603 specs <5% 1 KHz @ 60% dev. 50 45 Watts or 5 Watts ±2. 5 ppm (-30° to +60° C) 16KOF3E/11KOF3E 70 dB WB/60 dB NB 70 dB 45 dB WB/40 dB NB per EIA/TIA-603 specs <5% 1 KHz @ 60% dev. 50 ±2. 5 ppm (-30° to +60° C) 0. 25 V 70 dB WB/65 dB NB 70 dB WB/65 dB NB 70 dB WB/65 dB NB ±2 KHz WB/±1 KHz NB <12dB Sinad per EIA/TIA-603 specs 4 Watts <5% THD into 8 50 ±2. 5 ppm (-30° to +60° C) 0. 25 V 70 dB WB/65 dB NB 70 dB WB/65 dB NB 70 dB WB/65 dB NB ±2 KHz WB/±1 KHz NB <12dB Sinad per EIA/TIA-603 specs 4 Watts <5% THD into 8 50 136-174 MHz MMAMO1032 (50W) MMAMO7128 (70W) Part 90 8/32/128 8 12. 5/25 KHz 2. 5/5/6. 25 KHz 50 CTCSS/104 DCS 13. 6 Vdc ±15% 810 1. 73x6. 45x6. 38 in (44x164x162 mm) 3. 3 lbs (1. 5kg) MO-4128 (45W) UHF 430-470 MHz MMAMO4032 Part 90 8/32/128 8 12. 5/25 KHz 5/6. 25 KHz 50 CTCSS/104 DCS 13. 6 Vdc ±15% 810 1. 73x6. 45x6. 38 in (44x164x162 mm) 3. 3 lbs (1. 5kg) © 2007, Midland Radio Corporation http://www. midlandradio. com 25 OlympianTM Series Mobile Radio User's Guide OlympianTM Mobile Connectors 26 © 2007, Midland Radio Corporation http://www. midlandradio. com OlympianTM Series Mobile Radio User's Guide Warranty Statement Midland Radio Corporation (herein, Midland) warrants each new radio product manufactured or supplied by it to be free from defects in material and workmanship under normal use and service for a period listed below, provided that the user has complied with the requirements stated herein.
