Olympian™ Mobile User’s Guide © 2005, Midland Radio Corporation 11 Basic Operation Before turning on your radio for the first time, you should ensure power connections have been made correctly and all antenna connections are proper and secure. Turning the Radio On and Off Rotate the power/volume knob clockwise past the detent to turn on the radio. Rotate the power/volume knob further clockwise to increase the volume. Rotate the power/volume knob counterclockwise past the detent to turn off the radio. If “PP” is displayed after turning on the radio, you must enter the programmed password (4 keypress sequence) to use the radio. Consult your dealer or communications coordinator if you have further questions. Channel Selection Use the up and down keys to select the desired operating channel. Please consult your dealer or communications coordinator regarding channels programmed in your radio. Press and hold the up and down keys to quickly scroll through the available channels. Bank Selection Your radio channels may be organized into “banks” or channel groupings that further sort and organize your channels. Please consult your dealer or communications coordinator regarding channel banks programmed in your radio. To select a different bank of channels press the programmed Bank button, then use the up down keys to select the new bank. Once the desired bank is displayed press the A B C or D button to select it.
Olympian™ Mobile User’s Guide 12 © 2005, Midland Radio Corporation Receiving Transmissions from Other Radios Each channel of your radio may be programmed for carrier squelch operation, CTCSS/DCS operation or 2-tone operation. The following paragraphs describe these modes of operation. Ask your dealer or communications coordinator if you have questions on how your radio has been programmed to operate. Carrier Squelch Operation A signal that matches the programmed receive frequency will be heard if it is of sufficient strength to exceed the squelch threshold. An on frequency signal exceeding the squelch threshold level will be indicated by a steady green Tx/Busy indicator. CTCSS/DCS Operation CTCSS or DCS signaling adds an additional condition to carrier squelch operation. 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. 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.
Olympian™ Mobile User’s Guide © 2005, Midland Radio Corporation 13 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 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. Transmitting to Other Radios 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. 2. If the channel is clear, press and hold the push to talk (PTT) switch on the side of the microphone.
Olympian™ Mobile User’s Guide 14 © 2005, Midland Radio Corporation 3. The Tx/Busy indicator will glow red while the radio is transmitting. 4. Hold the microphone approximately 2 inches from your mouth and speak across the face of the microphone in a clear, normal voice. 5. Keep the PTT switch pressed until you have finished speaking. 6. Release the PTT switch to return to receive mode. Do not shout! It will only create distortion. 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. When you are transmitting, other people can not. Use common sense and do not occupy the channel too much. The radio might be programmed with a timeout timer which will automatically end your transmission after a preset time. In this case release PTT and wait for a few seconds. The radio transmitter will be enabled again after a few seconds. Ask your dealer or communications coordinator for further details. The radio might be programmed for busy channel lock out, which automatically disables the transmitter if your channel is busy. In this case wait until the channel is clear. Scanning Channels If you have more than one channel programmed, your Olympian™ radio may be programmed to allow you to scan them. To activate scan press and release the programmed function button. The radio will begin checking all channels in the scan list for activity. The scan icon will blink while the radio is scanning. To turn scan off press and release the programmed
Olympian™ Mobile User’s Guide © 2005, Midland Radio Corporation 15 function button again. If beeps are enabled a high pitched beep will sound when scan is activated and a lower pitched beep will sound when scan is turned off. The scan list is initially programmed by your dealer or communications coordinator. Your dealer may also have designated one or two channels in the scan list as a priority channel. The priority channel is checked for activity more often than other channels in the scan list. The priority channel will also be checked for activity while the radio is receiving on a non- priority channel. Once the receive signal ends, the radio may be programmed to wait a period of time before resuming scan. When the scan hang timer has expired, scanning will resume. This scan hang timer will also be started whenever the radio has ceased transmitting on a channel. Your dealer or communications coordinator will customize the scan options for your particular situation; the following paragraphs detail the available options. Busy Channel Scan If no priority channel has been assigned by your dealer or communications coordinator, all channels in your scan list will be checked for activity, with no preference given to any channel. If activity is detected on a channel the radio will stop on that channel. While the radio is stopped on a channel it may be temporarily deleted from the scan list by pressing a programmed Scan Skip or Monitor function button. This is the nuisance channel delete function. When the radio is turned off, all channels removed from the scan list using nuisance channel delete will be restored. Priority Channel Scan If a priority channel (or two) has been assigned by your dealer or communications coordinator, the priority channel will be checked more often than the other channels in the scan list. If activity is detected on a channel the radio will stop on that channel. While
Olympian™ Mobile User’s Guide 16 © 2005, Midland Radio Corporation stopped on a non-priority channel, the radio will continue to check for activity on the priority channel. This is called priority channel lookback, and the receive audio from the non-priority channel will be briefly interrupted while priority lookback occurs. While the radio is stopped on a non-priority channel it may be deleted from the scan list by pressing a programmed Scan Skip or Monitor function button. This is the nuisance channel delete function. The priority channel can not be deleted from the scan list. When the radio is turned off, all channels removed from the scan list using nuisance channel delete will be restored. Priority Select Scan If channel select priority scan has been programmed by your dealer or communications coordinator, the channel selected when scan is turned on will be assigned as the priority channel. Operation will otherwise follow the priority channel scan conventions. Transmitting While in Scan Mode If PTT is pressed while the radio is in scan mode, your dealer or communications coordinator may have programmed one of the following options for the transmit channel: 1. When PTT is pressed, the radio will generate an error beep because your dealer or communications coordinator has programmed the radio to not allow transmission while the radio is in scan mode. 2. When PTT is pressed, the radio will switch to and transmit on the priority 1 channel, priority 2 channel or other dealer programmed channel regardless of the current receive state. This mode may be referred to as priority only transmit. 3. If the radio has stopped on a channel, or the scan hang timer is active, the radio will transmit on the scan stop channel when you press PTT. If you press PTT, while the radio is scanning channels, the radio will switch to and transmit on the priority 1 channel, priority 2 channel or other
Olympian™ Mobile User’s Guide © 2005, Midland Radio Corporation 17 dealer programmed channel. This mode may be referred to as (priority) talkback transmit. Editing Your Scan List One of the advanced features of your Olympian™ mobile radio is the ability to add channels and banks of channels to your scan list. Of course, you may also delete channels and banks of channels from your scan list. These changes are saved in radio EEPROM and are not temporary like nuisance channel delete. The channels in your radio may be organized in banks and each bank may be selected for scan. Then within each bank, each individual channel may be selected for scan. To scan a channel, the channel must be in a bank included in the scan list and the channel must be in the scan list. As you are editing the scan list, if an “e” is shown in the upper right corner of the display, the channel or bank is included in the scan list. If a “D” is shown in the upper right corner of the display, the channel or bank is not in the scan list. Bank Scan Edit To add or remove a bank of channels from the scan list, press and hold the Bank programmable button for two seconds. Use the and keys to select the desired bank. Press the A key to enable (e) or disable (D) the bank for scan. Press the and keys to select another bank or press B C or D to exit. Channel Scan Edit To add or remove a channel in the current bank from the scan list, press and hold the Scan programmable button for two seconds. Use the and keys to select the desired channel. Press the A key to enable (e) or disable (D) the
