Default working channel in Open Scan modeIn the Open Scan mode, your default working channel is thechannel your radio switches to when you press the PTT whilescanning. To define your working channel simply select therequired channel before you press the SCAN key. e.g. to makechannel 24 your working channel, simply select channel 24before pressing the SCAN key.To talk on your working channel while scanning, simply pressthe PTT. The scan will pause and your radio will switch toyour working channel allowing you to transmit and receive onthat channel. Once your communication has finished and thechannel has been clear for 5 seconds, scanning will resume.If your radio pauses on a busy channel other than yourworking channel and you wish to talk on that channel, simplypress the PTT during a break in the conversation. The busychannel now becomes your new working channel, replacingyour previous working channel. Once your communicationhas finished and the channel has been clear for 5 seconds,scanning will resume.Scanning in Group Scan modeGroup scan mode is slightly different to Open Scan modein that the Group Scan allows you to communicate on yourPriority channel while continuing to scan a number of otherchannels. The receiver will scan the other channels ONLYWHILE THERE ARE NO SIGNALS ON THE PRIORITY CHANNEL.ChannelSignals being received on the priority channel it will overrideany signals being received on any of the other channels. Inaddition, if you press the PTT at any time the radio will alwaystransmit on the Priority channel.Setting up Group Scan1. See the ‘Selecting a Scan Group’ section on page 13 toselect the Group Scan mode.2. Store your preferred Priority channel as outlined under‘Priority Channel’ on page 12.3. Program the required ‘other’ channels into the scan groupmemory as described above under ‘To add or removechannels from the scan memory’ on page 13.To Scan in the Group Scan mode, briefly press the SCANkey. A high beep will be heard and the scan symbolwill animate. During this time the channel numbers will scrollrapidly as the selected channels are scanned with the Prioritychannel being scanned every fourth channel.If a signal appears on the Priority channel – at any time – theradio will switch directly to the priority channel and 3 shortbeeps will be heard. The radio will now stay on the prioritychannel for as long as the channel remains busy. During thistime you can transmit and receive on the priority channel inthe usual way. Once the priority channel has been clear for 5seconds the radio will resume scanning the other channels.If a signal appears on one of the other channels, scanningwill pause on that channel and will remain there while thechannel is busy – as long as there are no signals on thepriority channel. During this time, the receiver will continue tocheck the priority channel every 2 seconds resulting in a seriesof small breaks in the reception of the busy channel. Once thesignal has gone and there has been no activity on any channelfor 5 seconds, the radio will resume scanning.To transmit on the priority channel at any time, simply pressthe PTT. The radio will switch straight to the priority channel.When you have finished your conversation and there hasbeen no further activity for 5 seconds, the radio will resumescanning the other channels.If the scan pauses on a busy channel and you don’t wish tolisten to that conversation, rotate the channel switch and theradio will skip that channel and resume scanning.If the radio is paused on a busy channel and you want toremain there, briefly press the SCAN key. The radio will exitscan and remain on the bust channel. At this point you will nolonger be monitoring the priority channel.To resume scanning press the SCAN key again.To exit the scan mode and go directly to the priority channel atany time, press F then PRI.Scan Group optionsBy default your radio has one Open Scan mode and one GroupScan mode. There may be applications where you have noneed to monitor a priority channel and would prefer to havePA G E 1 4 I n s t r u c t i o n m a n ua l t X 3 5 1 0 / T X 3 5 2 0 / T X 3 5 4 0
two separate Open Scan modes. Alternately you may preferto have two separate Group Scan modes with different scanchannels in each. Your radio can be programmed to convertthe Group Scan into an Open Scan and vice versa. If this isrequired, please contact your <strong>GME</strong> retailer to arrange for thisfeature to be activated.When two Open Scan or two Group Scan modes are enabled,the Scan Group selection screen will display O1 and O2 for theOpen Scan groups or G1 and G2 for the Group Scan groups.See the section ‘Selecting a Scan Group’ on page 13.NOTE: Enabling or disabling the second Open or GroupScan mode is not a user selectable option. Once enabled ordisabled, the new scan mode becomes a permanent part ofyour radio’s features. If you decide later that you need theoriginal Scan mode settings restored you will need to returnyour radio to your <strong>GME</strong> retailer for re-programming.CTCSS & DCSThe standard squelch system is fine for quietening the radioin most applications. However it operates solely on signalstrength which means that it will always open to any signalthat is strong enough. If the channel is busy with otherstations the squelch will be constantly opening which canmake it difficult to determine which calls are meant for you.CTCSS/DCS provides additional selective receiver audio mutingusing sub-audio signalling. When enabled, only signals with amatching sub tone will be heard in the speaker. This effectivelycreates a channel that is silent to all traffic except those whouse the same subtone as you.Choosing CTCSS or DCSCTCSS uses a continuous analogue sub tone while DCS uses adigitally encoded sub tone. Choosing which tone system to usewill largely depend on the other radios you talk with. If othersalready use CTCSS or DCS, you should select the tone systemthat matches theirs. If the users you talk to don’t currently useCTCSS or DCS then you can make your own choice. There isno difference in performance or function between the differenttone sets. Both types are included in the radio to maintaincompatibility with other radio systems.CTCSS tone setThere are two CTCSS tone sets available – the basic 38 toneset or the extended 50 tone set (see the CTCSS tone chartat the rear of this manual). Both are included to ensurecompatibility with other radios.To switch between CTCSS tone sets;1. Switch the radio Off.2. Press and hold the SQL key while switching the radioon again.3. CTC38 or CTC50 will appear briefly.NOTE: When switching between tone sets, if you already havea CTCSS tone selected, the radio will try to match the originaltone frequency with one in the new table. If there is no tonematch, the CTCSS tone will be set to OFF and you will need toselect a new tone.DCS tone setThere are 104 DCS tones available (see the DCS tone chart atthe rear of this manual).To Select a CTCSS or DCS tone1. Select any UHF CB channel 1 – 80 (excluding 5 and 35).2. Press and hold the Menu key until the radio beeps. TheCTCSS Menu option will be displayed.3. If CTCOF is displayed, CTCSS/DCS tones are currentlyswitched off (default). To enable CTCSS tones, rotate theChannel knob to the right (or press ). CTCSS tones willbe displayed as CTC01 – CTC50.4. Continue rotating the Channel knob (or pressrepeatedly) to scroll past the last CTCSS tone (38 or 50) toaccess the DCS tones. DCS tones are displayed asDT001 – DT104.Pressor rotate leftPressor rotate rightCTCSS Off CTCSS Tone 50 DCS Tone 104T X 3 5 1 0 / T X 3 5 2 0 / T X 3 5 4 0 i n s t r u c t i o n m a n ua l PA G E 1 5
