The contents of the memory channel are replaced with new data. The original contents of the memory channel are automatically moved to the next memory channel. For example, if channel 3 is recalled, the frequency or the mode modified, and the QUICK MEMO M.IN key pressed, the new data is stored in channel 3, and the original contents of the memory channel are automatically moved to channel 4. If channel 5 is recalled, the frequency or mode modified, and the QUICK MEMO M.IN key pressed, the new data is stored in channel 5, and the original contents of channel 5 are automatically erased. 40 4-12. SCAN Both Memory Scan and Program Scan are possible. 4-12-1. Memory Scan During memory channel operation, pressing the SCAN key will cause the radio to scan the memory channels repeatedly, skipping the channels that have no data stored or are locked-out. To cancel scan press the CLR key. 4-12-2. Group Scan To initiate memory scan of specific memory channel groups. 1. During memory channel operation, press and hold the SCAN key. 2. You may specify which memory groups you want to scan by depressing the key that corresponds to the tens digit position of the memory channel group. 0 ....................Memory channels 00 thru 09 1 ....................Memory channels 10 thru 19 2 ..................Memory channels 20 thru 29 • • • • 9 ..................Memory channels 90 thru 99 In example 1 we want to scan only Group 2, so we would press the 2 key. In example 2 we want to scan Group 1 and Group 3, so we would press the 1 key and then the 3 key. Example 1 Group 2 CH20 * Example 2 Group 1 Group 3 CH10 CH19 СИЗО CH39 I______________________________I 4-12-3. Memory Channel Lockout This transceiver has a Memory Channel lockout function which allows you to temporarily skip unwanted Memory Channels during memory scan. Locking out unwanted channels will help to increase the effective scan speed. 1. Use memory channel for the RX VFO or both during memory channel operations. The display shows the memory channel operated last. CH29 i 2. Select the Memory Channel that you want to skip using the M.CH/VFO CH control. 3. Press the CLR key. Note Holding the CLR key depressed for longer than 2 seconds will clear that channel of all data. 4. A decimal point will appear in the M.CH display to indicate that the channel will be skipped. 5. To cancel the lockout, select the desired channel and then press the CLR key. The decimal point will go out indicating that the channel will again be scanned. Note If memory scan is initiated while all Memory Channels are locked out a Morse code “CHECK” will sound from the speaker. 4-12-4. Programmable Band Scan Pressing the SCAN key during VFO A or VFO B operation starts the scan. Channel Selection 1. While holding the SCAN key depressed press the numeric key that corresponds with the program scan range you want to scan. For example press the 3 key if you want to scan between the limits specified in memory channel 93. Press 4 if you want to scan between the limits specified in memory channel 94, and so on. 2. Scan will proceed from the frequency that appears in the highest frequency towards the frequency specified in the lowest frequency. 3. The mode of operation and filter bandwidth can be changed during scan. 4. To cancel scan press the CLR key. Note If no data has been stored in memory channel 90 scan will proceed from 30.0 kHz thru 30.0 MHz and these limits will be automatically stored in memory channel 90. (Initial state) You can specify up to 10 different groups to scan. Simply hold the scan key depressed and press the numeric key corresponding to the different groups you wish to scan. For example: When 14.000 MHz (lower limit) and 14.010 MHz (upper limit) are stored in channel 91, and 21.000 MHz (lower limit) and 21.010 MHz (upper limit) are stored in channel 92: [ I ] Press Numeric key 1 while holding down the SCAN key. Scanning will proceed thru the range stored in memory channel 91. 41 Memory channel 91 14.000 14.010MHz I-*1 t i [II] Press Numeric key 2 while holding down the SCAN key. Scanning will proceed thru the range stored in channel 92. Memory channel 92 21.000 21.010MHz 1 i [III] Press Numeric keys 1 and then 2 while holding down the SCAN key. Scanning will be repeated within the ranges stored in channels 91 and 92. Memory channel 91 Memory channel 92 14.000 14.010MHz 21.000 21.010MHz I-4............*1--I A 4-12-5. Scan Speed The scanning speed is adjustable from the front panel by using the RIT/XIT control during SCAN operations. Clockwise rotation increases the scan speed and counterclockwise rotation decreases the scan speed. This speed adjustment is effective in both VFO and M.CH scan modes. Once set the scan speed remains in memory until it is again changed by the RIT/XIT control. You must be in the SCAN mode in order to alter the scan speed. The approximate scan speed adjustment range is shown below. 700Hz 50Hz 20...
