POWERINg THE RADIO Your TX670 is powered by three AA batteries (Ni-MH). If left unused, the batteries will discharge within a few months. If you have not used your TX670 for some time, you will need to recharge your batteries before use. Installing the Batteries Battery installation is more convenient when the belt clip is removed. To do this, release the spring clip and slide the belt clip downward and away from the radio body. 1. P ress the centre top area of the battery cover and slide downwards. 2. I nstall the three rechargeable batteries as indicated on the battery housing, slide cover back into position until it ‘clicks’ into place. TX670 Instruction Manual... -
Page 6: Charging The Batteries
Charging the Batteries Your TX670 is supplied with an AC adapter which will recharge a fully discharged set of 1500 mAh batteries to full capacity in around 15-16 hours. 1. P lug the charger into a standard 240 Volt AC outlet. 2. C onnect the charger to mic/charge socket on the radio. Battery Low Alert When the battery icon blinks on the display, the battery level is low and the batteries should be recharged or replaced. If the batteries are not charged, an audio tone will then sound to warn the user that the batteries are almost discharged. Battery Usage The time taken to discharge the batteries will depend on how you use the TX670. The 1500 mAh batteries supplied are powerful enough for a full days use under average conditions. Conserving Battery Power The TX670 has built-in power saving features to help you get the maximum amount of time between charges. If you need to operate your TX670 in a situation where you require maximum battery life (e.g. a remote site where there is no convenient recharging facility nearby) the following hints can greatly reduce the amount of power drawn from the batteries. Standby Mode The TX670 will automatically enter the ‘Standby’ mode when it is inactive (i.e. not transmitting or receiving signals). While in Standby mode it will still check for incoming signals but it will draw considerably less power from the batteries. As soon as a signal is heard or the keys are pressed the TX670 will ‘wake up’ again. This Standby mode is automatic and by itself can... -
Page 7: General Operation
CTCSS tone is received. Scanning The TX670 draws more power from the batteries when scanning than when monitoring a single channel. This is because it must ‘wake up’ more often to monitor each channel for activity. You can lengthen the battery life by avoiding any unnecessary scanning. In addition, scanning increases the chance of finding a signal thereby keeping the receiver ‘awake’ and the Squelch open more often. Low Transmit Power Settings The transmitter has both high and low power settings. If you are only operating over short distances, are in a reasonably high location or are close to a local repeater, try using the Low transmitter power setting. This reduces the transmitter power from 2 Watts to 1 Watt effectively doubling the talk time available. gENERAL OPERATION Power On/Off Rotate the Volume control clockwise past the ‘click’ to turn the radio ON. Rotate the control counter-clockwise past the click to turn the radio OFF again. -
Page 8: Receiving Signals
Receiving signals While the TX670 is not receiving signals, it will remain in the Standby mode to conserve battery power. When a signal is received, the LED indicator on the upper edge of the radio will light green and the icon will appear on the display. Adjust the Volume control for a comfortable listening level. If the incoming signal is encoded with a CTCSS tone that matches the one set in your radio, the LED indicator will light orange and you will be able to hear the signal in the speaker. If the LED indicator lights green and the icon appears but you cannot hear the signal, it is likely that your radio has CTCSS enabled and the incoming signal is not using your selected CTCSS tone (see ‘Mode Settings’ for more details on CTCSS settings). If no further signals are received, the unit will revert to Standby mode. Transmitting To transmit, press and hold the Push-To-Talk (PTT) switch. The other radio you are talking to must be set to the same channel (and CTCSS code if applicable). Hold the TX670 approximately 5 to 8 cms from your face with the antenna vertical and speak into the built-in microphone. While the PTT switch is pressed, the LED indicator on the upper edge of the radio will light red and the icon will appear on the LCD. When you have finished speaking, release the PTT switch to receive incoming signals (it is not possible to transmit and receive at the same time). If no further signals are received, the unit will revert to Standby mode. TIP: The PTT switch can also be used to transmit a Call Alarm melody. When the Call Alarm melody is enabled (see Mode settings for more details on the Call Alarm settings), pressing the PTT switch twice quickly will call another party on the same channel and play the Call Alarm melody in their radio’s... -
Page 9: Dup/Monitor Key
Duplex/monitor Key The Duplex/Monitor key is a dual function key that controls both the Duplex and Monitor functions. DUP Key Duplex operation allows the TX670 to transmit on a different frequency to that which it receives. This allows operation through repeater stations in your area. Repeaters automatically re-transmit your signal over a much wider area, providing greatly increased range. The Duplex mode only works on channels 1 - 8. With Duplex selected, your TX670 actually transmits 30 channels higher than it receives. Channel Selected Receive Channel Transmit Channel To switch between Simplex and Duplex modes, select a duplex channel (1-8) then briefly press the DUP button. When Duplex mode is selected, ‘DUP’ appears on the display on that channel. MOn Key To open the Squelch, press and hold the MOn key. This will allow you to check the current channel for activity before transmitting, particularly if you have CTCSS enabled. When the Squelch is open, the LED indicator on the upper edge of the... -
Page 10: Scan/Memory Key
SCAN/memory Key The SCAN key is a dual function key that controls both Scan and Memory Functions. Scanning Function Channel Scanning allows you to monitor channels that have been included in the active scan list. The active scan list includes all channels which display the icon ‘M’ on the LCD. To enable channel scanning, briefly press the SCAn key. ‘SCAN’ will be displayed and the radio will show rapidly changing channel numbers as it scans through the channels. While scanning, briefly press the keys to select the scan direction. To exit the Scan mode, briefly press the SCAn key again. The TX670 will return to normal operation and ‘SCAN’ will disappear from the display. Scanning Features • I f a signal is received, the scan is paused, allowing you to transmit and receive on that channel. The radio will automatically resume scanning a few seconds after the last reception or transmission. • P ress the PTT switch while the unit is scanning to jump to the home channel (the home channel is the channel the radio was on at the time scanning was activated). You can then transmit and receive on that channel. The radio will automatically resume scanning a few seconds after the last reception or transmission. • W hen the unit has stopped on a busy channel, press the keys to ‘skip’ over the busy channel and continue scanning. -

Memory Function The Memory function enables and disables the current channel to be memorised into the scanning list. When the channel is memorised with the ‘MEM’ icon on the LCD, scanning will include the channel. When the channel is deleted from the scanning list, the channel will be skipped upon scanning. All channels are saved to Memory during manufacture. To disable the Memory, press and hold the SCAn/MEM key. mode/Key-Lock Key MODE function MODE key is used to set the various feature settings of the TX670.
