Basic Operations VFO mode VFO tuning is set as a default mode at the factory. VFO (variable frequency oscillator) allows you to change the frequency in accordance with the selected channel step as you rotate the main dial or by using the UP/DOWN keys on the microphone. VFO mode is also used to program the data to be stored in the memory channels or to change the parameter settings of the transceiver. 1. Identify the current mode by checking the display.
Basic Operations Setting the channel step 1. When the unit is in VFO mode, enter into the SET mode and select the channel step setting display. (Refer to page 32 and 33 for SET mode). 2. The current channel step will be displayed. 3. You can change the channel step as below by rotating the dial. 4. Channel step setting display (default) STEP 5 (5 kHz) STEP 8.33 (8.33 kHz) STEP 10 (10 kHz) STEP 12.5 (12.
Basic Operations Shift Direction and Offset frequency setting Conventional repeaters are operated in the DUPLEX mode, which receives an incoming signal on one frequency and re-transmits on another. The difference between these two frequencies is called the offset frequency. The offset is variable between 0 to 99.995MHz on this unit. 1. After pressing the FUNC key, by pressing MHz key while [F] appears on the display, the display will show the current status of offset frequency and shift direction.
Basic Operations Memory Mode This mode allows recalling and operating the preprogrammed frequency or setting. This unit provides up to 200 memory channels (80 exclusive channels each for VHF and UHF, from 00 to 79CH and 40 common channels for VHF and UHF, from 100 to 139), 1 CALL channel each for V and U (C), 1 program-scan edge memory channel each for V and U (PL) (PH) and 1 VFO automatic program setting channel (AL) (AH). Recalling a memory channel 1. 2. Select the memory mode by pressing V/M key.
Basic Operations How to program memory 1. Select a frequency to be programmed in the VFO mode and set the parameters as appropriate. Refer the next page for programmable parameters. 2. By pressing FUNC key, [F] and [Memory No.] icons will appear on the display. 3. Rotate the main dial (or press UP/DOWN key) to select the desired memory channel number. 4. An empty channel is shown with a flashing [Memory No.] icon. 5.
Basic Operations Memory channel deleting 1. Select the memory mode by pressing V/M key. 2. Select the desired memory channel number by rotating the main dial. 3. The programmed memory channel has the memory number illuminated on the display. 4. By pressing M/W key together with FUNC key while [F] icon is on, a beep will sound and the memory will be deleted. At the same time, [Memory No.] icon will start flashing.
Basic Operations Channel name (Alphanumeric) registration function The memory channels stored in the memory mode can be displayed with an alphanumeric tag instead of the default frequency display. There are 67 characters available including A-Z, 0-9. 1. In the memory mode, select a channel to be programmed. 2. Press the H/L key together with the FUNC key. 3. The display shows [A ] flashing. 4. Rotate the dial to select a character to be programmed. 5.
Basic Operations 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. The default setting is 145.00MHz/433.00MHz, and available 1ch each on VHF and UHF band. To recall a CALL channel Select the desired VHF or UHF band by pressing BAND key. 1. Press CALL key. The C icon appears on the display and the transceiver enters the CALL mode.
Basic Operations Monitor function A Monitor function is available to receive weaker signals. Press and hold SQL key for more than 1 second. Regardless of the level setting of the squelch, it will be opened and the Busy icon/RX lamp turn on the display. Press any key on the front panel to exit. BUSY IMPORTANT: Monitor function only operates on the MAIN band. Monitor function operates irrespective of Tone squelch/DCS function setting.

Parameter Setting Mode To use the parameter setting mode 1. Press the FUNC key for more than 2 seconds to enter the parameter Setting mode. 2. Select a menu by pressing the FUNC key and the SQL key, or UP/DOWN keys on the microphone. 3. Rotate the main dial to change the setting. 4. Pressing the FUNC/SQL and UP/DOWN key will complete the setting and enters to the next menu. 5. Pressing any key other than the FUNC/SQL and UP/DOWN key will complete the setting and exits the parameter setting mode.
Parameter Setting Mode (Refer page 27 for how to enter the setting mode.) Channel Step setting This is to select the channel step to be used in the VFO mode. Refer to the chart below for the relation of the actual step frequency and how it is displayed. STEP 5 (5 kHz) STEP 8.33 (8.33 kHz) STEP 10 (10 kHz) STEP 12.5 (12.5 kHz) STEP 15 (15 kHz) STEP 100 (100 kHz) STEP 50 (50 kHz) STEP 30 (30 kHz) STEP 25 (25 kHz) STEP 20 (20 kHz) NOTE: The default is as follows. • DR-620E [STEP 12.
