Function KeyS Squelch Control There are four keys beneath the TX3440’s display that have both primary and secondary functions. Their primary functions are printed in Black while their secondary functions are printed in Red. Squelch control is used to eliminate the background noise when there are no signals present. The TX3440 features a preset Squelch system.
To Recall a Priority Channel quiet again. Transmissions that do not use the correct tone will not be heard. Briefly press the PRI key. The radio will switch straight to the selected Priority Channel. Any active functions (such as scanning or Quiet) will be cancelled. The TX3440 allows CTCSS to be enabled or disabled on individual channels. Duplex Operation Duplex operation allows the radio to transmit on a different frequency to which it receives. This allows operation through local repeater stations.
SCANNING The TX3440 has a SCAN function that allows groups of user programmable channels to be scanned for signals. Channels can be scanned at 20 channels per second. When a signal is found, scanning will pause on that channel to allow the signal to be heard, then resume scanning when the channel is clear again. Scan Groups The TX3440 features two scan groups Open Scan and Group Scan. Open Scan Allows any of the installed channels to be scanned for activity.
• If your radio is paused on a busy channel and you wish to remain there, briefly press the SCAN key. The radio will exit Scan mode and remain on the busy channel. • To transmit while paused on a busy channel, simply press the PTT button. The radio will exit Scan mode and remain on the busy channel. You can now converse on that channel in the usual way. When you have finished your conversation, briefly press the SCAN key to resume scanning.
Using two Group Scan or two Open Scan modes Selcall Identification Number If you prefer, the TX3440 can be re-programmed to have two Group Scan modes or two Open Scan modes instead of one of each. For example there may be applications where you have no need to scan the Priority Channel and would prefer to have two separate Open Scan modes. Alternatively you may have applications where you prefer to have two Group Scan modes with different Scan groups in each.
You can activate QUIET mode on individual channels i.e. some channels can be set to remain quiet while others can remain open to all incoming signals. TIP: Setting QUIET mode is not mandatory. You can still use Selcall on any channel whether the QUIET mode is set or not. Selcall Memories Your TX3440 is fitted with one Call memory and 10 Selcall Ident memories. The 10 Selcall Ident memories are used to store frequently used Selcall Idents.
Naming your Selcall Idents The TX3440 allows you to name each Selcall Ident using a 5 character ALPHA name. The name is stored in memory along with the Ident making it easier to identify whose Ident you are recalling from the memory. If an incoming Selcall matches one of those in your radio’s memory, the name can be displayed instead of the Selcall Ident. Displaying ALPHA Names (b) Briefly press the PRI key again to select the next character position.
To cancel the alarm and listen on the channel Briefly press the QUIET key (if QUIET has been activated). The alarm will stop beeping and the channel will remain open to any incoming signals. Receiving Signals in QUIET Mode QUIET Mode (Q) QUIET mode mutes the TX3440’s receiver to prevent any incoming signals from being heard in the speaker until your Selcall Ident is received. In this way you can monitor a busy channel for personal calls without being disturbed by unwanted signals.
Receiving Signals while scanning in QUIET Mode • Transmitting 1233A will activate the alarms in all radios with Idents 12330 through 12339 (a total of 10 radios). • If a normal signal is received on an open channel, scanning will pause while the channel is busy and will resume scanning 5 seconds after the channel becomes clear. (If you were scanning in Group Scan mode, the radio may switch between the Open channel and the Priority Channel - this is normal).
Receiving Group Calls Receiving a Group Call is identical to receiving a normal Selcall except that the alarm sound is a LOW tone beep instead of the normal HIGH tone beep. The Callers Ident or ALPHA Name appears on the display in the usual way. 6. Once you have enabled and programmed your additional listening channels, switch the radio OFF to end the initial programming operation.
• To delete a currently active listening channel, edit the frequency as described above, but press the or keys left until the display shows ‘OFF’. Once the channel data is saved and the menu exited (by pressing and holding the MENU key) the deleted listening channel will only be visible again if the ‘All Visible’ mode is selected, as described in the Initial Programming section on page 13. To program additional listening frequencies Repeat steps 1-5 above.
SETTING SEEK MODE FREQUENCY LIMITS When in Seek mode, the default frequency band to scan is the entire receiver tuning bandwidth of 403 MHz-520 MHz. However, in many cases you may only be interested in searching for signals within a small section of the available frequency band. To make searching easier the TX3440 allows you to set upper and lower frequency limits. The Seek function will then only search within the specified range, thereby increasing the chance of finding an active frequency of interest.
SETTING THE SQUELCH SENSITIVITY MENU SETTINGS The MENU feature provides a convenient method of customizing or storing some of the radio’s functions. The following Menu Options are available. Note that some items are only available on certain channels.
The TX3440 allows you to select Duplex operation individually on each channel. 5. Press and hold the MENU key until the radio beeps, to store the setting. To enable or disable Duplex on a channel Backlighting 1. Select the required channel 1-8 (the Duplex setting feature is only available on these channels). Backlighting can be set to ON or OFF to satisfy personal preference CTCSS TONES 1. Press and hold the MENU key until the radio beeps.
Fitting the LCD Controller Microphone INSTALLATION The TX3440 main unit is supplied with a slim, slide-on mounting cradle. The cradle can be screwed or bolted in any convenient location in your vehicle (under or above the dash, on the centre console, under the seat, in the boot, etc.) using the mounting slots provided in the base. The main unit contains a built-in speaker, and can be installed in a convenient location in the vehicle’s cabin as the radio’s loud speaker.
Removing the Radio Console Mounting the TX3440 For console mounting, a flush mounting DIN Adaptor MBD001 is available as an optional accessory. The adaptor includes mounting brackets and a specially designed front panel escutcheon to suit most vehicle installations. The console mount is particularly suitable for dashboard mounting TX3440’s main unit. Installation instructions are provided with the bracket. See your nearest GME retailer for details.
