To turn the power OFF, hold the key down until the display disappears. will be displayed on the LCD indicating the present volume level. 4 Basic Operations Caution When you turn it on through the external power supply of a voltage of over 6.
4.3 Adjusting the Squelch The squelch is a function for eliminating noise which is generated when none of the signals are monitored. "To open squelch" means that the DJ-C7 monitors any of the higher signals than the squelch level you set, and the receiving sound will be heard. • There are 10 squelch levels. (0-9) • Default is set as 3. 4 1. Press the dial twice. 4.4 Operating Modes The DJ-C7 has two operating modes; VFO mode and Memory (MR) mode.
■Entry Completion Digit for Different Tuning Steps 4.5 VFO Mode This is a mode which is set as the factory-shipped configuration. Radio frequencies and various settings can be changed by rotating the dial in this mode. 1. Press the key to select the band to be changed its tuning step. ■Switching the Band Everytime you press the BAND key, below 7 bands can be switched in order. 145.000(142.000~169.995MHz) 380.000(380.000~429.995MHz) 433.000(430.000~469.995MHz) .531(531~1620kHz) 1.625(1.625~9.995MHz) 76.
4.6 Memory Mode This mode allows you to program frequencies into the DJ-C7 memory. A programmed frequency is called as a channel. The DJ-C7 has four types of memory functions; Memory channel (general), Program scan channel, Priority channel, and VFO auto programmed channel. ■Types of Memory Memory channel (general) (0-199) 4 Basic Operations Program scan channel (OA, Ob-4A, 4b) Priority channel (PRI) VFO auto programmed channel (AH, AL) This is a channel which is called up in Memory mode.
■Clearing a Memory Channel ■Contents of Memory Channel The following settings can be stored in each memory channel. 1. Set Memory Write Protect function to "OFF" state, if necessary. For more information on this function, please refer to "Memory Write Protect function" on P.XX. 2. Press the key to switch to the Memory mode. 3. Rotete the dial to select the memory channel number you want to delete. 4 key while the Basic Operations 4. Press the key, and press the F icon appears on the LCD.
4.7 Receiving 1. Adjust a volume level. (See on P.XX) 4.8 Transmitting 1. Select a frequency on which you want to transmit signals. 2. Adjust a squelch level. (See on P.XX) 2. Press the PTT key. 4 Basic Operations 3. Select a frequency on which you want to receive signals. When the red TX/RX indicator lights, it is now ready for transmitting.
5. Advanced Operations 5-1 Scanning 3. Release the This function automatically detects receiving frequencies to help you locate the signal that you want to receive. There are two types of scanning; Busy scan and Timer scan. The default is set as Busy ("bUSY") scan. Switching between those two types can be done in the Setting mode. (See on P.XX) Busy scan: If no signal is monitored after scanning stops, it will detect the next frequency.
4. Rotate the dial in the clockwise direction to make the scanning take place in the UP direction. Conversely, rotate the dial in the counter-clockwise direction to make the scanning take place in the DOWN direction. 5. Press any key other than the MONI key to stop scanning. ■Memory Scan Scanning is performed to detect signals among programmed frequencies as the memory channels. Memory channels need to be set in advance. Otherwise, the following operations can't be done.
5.4 Priority This function monitors two frequencies alternately to increase efficiency for receiving signals. Every 5 seconds, the DJ-C7 momentarily switches from a specified frequency to the frequency which is programmed as a priority channel (see on P.XX) for 0.5 seconds. 1. Hold the key down for a second to start the Priority monitoring function. 5.
6. Repeat steps from 1 to 4, and press the the state of step 4. key in After "XX" is displayed, press the key again to display . With the OFF state, press the PTT key or leave 5 seconds as it is to release the Tone Squelch function. 7. While "XX" is displayed on the LCD, press the PTT key or leave 5 seconds as it is to perform the Reverse Tone Squelch. To release the Reverse Tone Squelch function, press the PTT key or leave 5 seconds as it is while "XX" is displayed.
6. Parameter Setting Mode The DJ-C7's Setting mode is used to set the various operating functions. 6.1 Mode Setting Items (1) Audio Volume Level (2) Antenna Type (3) Repeater function (4) Tone Burst Frequency (5) APO (Auto Power Off) 6.2 Selecting the Setting Mode 1. Press the key, and press the dial once while the F icon appears on the LCD. It switches to the Setting mode, and the item name will be displayed on the LCD. 2. Select an item by pressing the dial.
1. " 6.3 Selecting the Parameters The following 11 functions can be set in the DJ-C7's Setting mode. " is displayed on the LCD. 2. Rotate the dial to select an antenna between Earphone and External (SMA) as follows. "SmA" (1) Audio Volume Level -> "EAr" When you use an earphone, you may reduce entire volume level with this function if the volume is too loud. (3) Repeater function 1. " " is displayed on the LCD. 2. Rotate the dial to switch HIGH/LOW of the volume level as follows.
(5) APO (Auto Power Off) This function automatically turns the power OFF if there is no key operation for a specified period of time to prevent battery charge wastage. This is useful if you easily forget to turn off the transceiver. 1. " • The factory-shipped default is set as ON. • This function will be released temporarily when the DJ-C7 receives signals or there is a key operation. • This function will not be performed while the DJ-C7 is under scanning. • LCD displays even with the hibernation state.
(11) AM / FM (9) Memory Write Protect function This function prevents from overwriting or deleting memory channels by mistake and protects what you've programmed. You can always program frequencies to blank channels regardless of this setting. 1. " You can select a modulation mode between AM and FM. It is necessary to switch a display for setting a tuning step in a specified band in advance. For more information on this, please refer to "Entry Completion Digit for Different Tuning Steps" on P.XX.
7. Cloning 2. Wait for a while until master data is transferred completely. 7.1 Cloning With the Cloning function, it is possible to connect two transceivers by a cable, and copy all settings from one unit (call as a Master) to the other (call as a Slave). This function transfers all master's settings including memory channel data. ■Connecting the Transceiver • Connect both of the speaker jacks on the sending transceiver (Master side) and the receiving transceiver (Slave side) with a ø 2.
2. Press the dial. " " is displayed on the LCD, and the master's transceiver starts to transfer data. " " is displayed on the LCD when transfer is completed successfully. 3. Turn the power OFF on the master's side to release the Clone mode. 7 Cloning If the DJ-C7 should fail to transfer data, " " is displayed on the LCD. When you see the indicator, redo from step 1.
