  • Page 16: Vfo Mode

    5. Basic Operation VFO mode VFO tuning is set as a default mode at the factory. VFO (vari- able frequency oscillator) allows you to change the frequency in accordance with the selected channel step as you rotate the VFO mode main dial or by using the UP/DOWN keys on the microphone.

  • Page 17: Changing The Channel Step

    5. Basic Operation Changing the channel step Be sure the unit is in VFO mode. Refer to page 21 to enter into the SET mode. Select the channel step parameter setting using Display for channel step the tuning knob. The current channel step will be displayed as below.

  • Page 18: Ctcss / Dcs Setting

    5. Basic Operation CTCSS / DCS setting Many repeaters require a CTCSS tone or a DCS code encode setting as a “key” to access the system, so-called “selective-calling”. Sometimes, CTCSS or DCS decode features are used on the output of a repeater so they can be used as a squelch. In this mode, regardless of the main squelch status, the audio can be heard ONLY when the matching tone/code signal is received.

  • Page 19: Memory Mode

    5. Basic Operation Memory Mode The memory mode on this transceiver provides up to 100 channels (0-99), 1 call (quick recall ch) and a pair of program-scan “edge memory” channels for quick, easy access to the preprogrammed frequencies with different parameter settings. Press V/M key.

  • Page 20: [Programmable Data In The Memory Channel]

    5. Basic Operation While F icon is on the display, press MW key. The VFO settings are copied to the memory channel and a beep will sound. The memory channel can be over-written if a previously pro- grammed channel is selected (the memory channels shown with a stable M icon).

  • Page 21: Call Mode

    5. Basic Operation CALL mode This is a memory mode that allows the transceiver to quickly recall the assigned memory channel by simply pressing the CALL key, regardless of the current status of the unit. Press CALL key. The C icon appears on the display and the transceiver enters the CALL mode.

  • Page 25: Time-Out-Timer

    6. Parameters Setting Mode Time-Out-Timer The TOT feature is popular in repeater systems. It prohibits the users from transmitting on the repeater after a certain period of time has elapsed. By setting this function and activating it accord- ing to the repeaters’ requirement, the radio alerts the user by a beep 5 seconds prior to time-out. When the time is expired, transmitting stops and the transceiver automatically returns to receiving mode.

  • Page 26: Apo-Auto Power Off

    6. Parameters Setting Mode APO-Auto Power OFF This feature will automatically shut off the transceiver. It is useful for mobile operation to avoid draining the car battery. If there is no activity or use of the radio, it will turn off automatically after 30 minutes followed by a beep sound.

  • Page 27: Alphanumeric Tag

    6. Parameters Setting Mode Alphanumeric Tag The memory channels stored in the memory-mode can be displayed with an alphanumeric tag instead of the default frequency display. Program the memory channel first. There are 67 characters available including A-Z, 0-9. Enter the set mode while the unit is in memory mode.
