21、elector memory channels when writing frequency and other information to memory channels. Second time: 01 USB only. The others are blank. 1) When DIAL is turned, channels, including those not en- tered in memories, are switched continuously. 1) Turning the DIAL changes the digit to its minimum fre- q

22、uency setting. 2) When the setting of one digit is completed, press SCAN to move to the next digit. Digits are set in order from the 10MHz digit to the 10Hz digit. (When setting the 10Hz digit, for example, the display shows the previously en- tered digits: 12.345.56) 3) Pressing DATA enables the tr

23、ansmit frequency write mode. Note: Setting begins from the 10MHz digit when the receive fre- quency write mode is first enabled. The set frequencies are checked to confirm they are within the specified receive frequency range. Setting all digits to “0” initializes the memory channel. In the receive

24、frequency write mode, the digit being set flashes as it displays the frequency. 2) Pressing DATA enables the receive frequency write mode. Receive frequency write mode (00.000.00) This mode is for writing receive frequencies to memory channels. The frequency is set in single digits starting from the

25、 10MHz to the 10Hz digit. The 1Hz digit is defaulted to “0”. 01027980. If the transmit frequency happens to be the default setting (00.000.00), when writing the receive frequency is com- pleted, the receive frequency setting is automatically writ- ten to the transmit frequency memory channel as well

26、. Leading zeros are not suppressed in the frequency dis- play. Transmit frequency write mode (00.000.00) This mode is for writing transmit frequencies to the memory channels. The frequency is set in single digits start- ing from the 10MHz digit to the 10Hz digit. The 1Hz digit is defaulted to “0”. 1

27、) Turning the DIAL changes the digit to its minimum fre- quency setting. 2) When the setting of one digit is completed, press SCAN to move to the next digit. Digits are set in order from the 10MHz digit to the 10Hz digit. 3) Pressing DATA enables the type of emission (MODE) write mode. (When setting

28、 the 10Hz digit, for example, the display shows the previously entered digits: 12.345.56) 4) When wishing to use the memory channel as a receive- only channel, set all digits to “0”, then press DATA to enable the type of emission (MODE) write mode. Note: Setting begins from the 10MHz digit when the

29、transmit frequency write mode is first enabled. The set frequencies are checked to confirm they are within the specified transmit frequency range. Setting all digits to “0” changes the memory channel to a receive-only channel. In the transmit frequency write mode, the digit being set flashes as it d

Transfer Mode This mode is used to copy the memory

41、 and menu data from one TK-80 unit to one or more others to create “TRANS”. 6-1. Procedure 1) Connect a cross cable (E30-3232-05) to the ACC1 connec- tors on two TK-80 units, as shown in the figure. 2) Turn on the power of the unit receiving the data. 3) Enable the Dealer mode in the unit to be tran

42、sferred, then press DATA. As the unit enters the Dealer mode, it automatically de- tects the connected second TK-80 unit, displays “TRANS” and begins the transferring transmission. 4) When transferring ends normally, the first TK-80 returns to the Dealer mode which is then shown on its display. Note

43、: Transfer is not possible when the destination diode (D8, D9, D10, D15) setting of the two units differ. Transfer is not possible when neither of the two units is equipped with transmit power setting diode (D7). 7. VFO Functions Dip SW3 is set to ON when shipped from the factory. Should the VFO mod

44、e fail to function, please check to see that Dip SW3 is set to ON. 7-1. Procedure 1) Press MENU to enable the user Menu mode. 2) Press DATA or MODE to select No. 00. 3) Use DIAL to switch the memory to VFO. 4) Press MENU to select VFO. 7-2. Description 1) DIAL changes from selecting memory channels

45、to se- lecting VFO frequencies. 2) SCAN changes to selecting the step frequency and the F. LOCK function. Pressing SCAN scrolls through the settings in the follow- ing order: 10Hz F. LOCK 100kHz 1kHz 10Hz Turning the DIAL after changing the step frequency rounds the lower digit off to “0”. 3) When i

46、n the user Menu mode, memory channel frequen- cies and type of emissions (MODE) are set in the VFO at the point control is switched from Memory to VFO. 4) DIAL and MENU are disabled during F. LOCK. 5) Even if AT tuning is established during VFO, the changing of the frequency automatically credits th

47、e state of AT through. 8. Personal Computer Interface In addition to commands (in the instruction manual) made available to users, the SR (system reset) command is made available only to dealers. Note: SRP1 = Reset the user menu SRP2 = Reset all The reset user Menu command resets all menu settings to the factory defaults. REALIGNMENT TK-80 7 9.
