Olympian™ Series Mobile Radio User’s Guide

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.

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

Olympian™ 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.

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.

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.

Olympian™ Series Mobile Radio User’s Guide

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™ mobile 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 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

Olympian™ Series Mobile Radio User’s Guide

than other channels in the scan list. The priority channel will also be checked for activity while the radio is receiving on a nonpriority 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 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.

Olympian™ Series Mobile Radio User’s Guide

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 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,

Olympian™ Series Mobile Radio User’s Guide

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.

Midland offers to the original end user a Three (3) Year Limited Warranty on Midland Business and Industrial radio products. Accessories carry a One (1) Year Limited Warranty.

During this period, if the product fails to function under normal use because of manufacturing defect(s) or workmanship, it should be returned to the Authorized Midland Sales and Service Outlet from which it was purchased. The Sales and Service Outlet will repair the product or return the product for repair to Midland or its Authorized Repair Depot.
