4-4. SCAN

Both Memory Scan and Program Scan are possible. In the AM and FM modes, scanning stops when the BUSY indicator lights. (This is known as Time Operated (about five seconds) Scan.) Time Operated Scan can be changed to Carrier Operated Scan (in which scanning stops when an AM or FM signals is present). Consult the authorized KEN- WOOD dealer where you purchased the radio from for modification information.

Notes:

1.The BUSY indicator lights in the following cases:

(A)When the SQL knob is turned counterclockwise from the point at which the squelch circuit mutes the audio (threshold).

(B)When an input signal is present.

2.If the present mode is other than AM or FM, Time Oper- ated Scan will be applied regardless of where the SQL knob is set or whether input signals are present or not.

4-4-1. Memory scan

The R-5000 stops on a busy channel in the AM or FM modes. The radio will remain on the busy channel for approximately 5 seconds and then start to scan again.

To initiate memory scan of all memory channels

1.Press the VFO/M key to select the Memory Channel mode.

2.Press the SCAN key. Scan will begin at memory chan- nel 00, or the lowest numbered channel containing data.

3.You can stop scanning by pressing the CLEAR key.

4.To resume scan press the SCAN key again. Scan will resume from the point that you stopped.

To initiate memory scan of specific memory channel groups

The 100 memory channels are divided into 10 groups (00 to 09,10 to 19, .... , 90 to 99). All Memory Channels in the

groups are scanned.

1.Select Memory Channel operation.

2.While pressing the SCAN key, select the desired group(s) number using the Numeric Keypad.

A maximum of ten groups can be selected. Scanning will proceed from lower numbered groups to higher numbered groups regardless of the sequence of select- ed group numbers.

Note:

All scanning groups (0 to 9) are selected upon shipment from out factory and when the microprocessor is reset.

3. When you release the SCAN key, scanning starts. Notes:

1.If no valid memory channel exists in a selected group, scanning will be automatically reset and memory chan- nel restarts. A valid memory channel is one channel which is not locked out and in which a frequency is stored.

2.Locked-out Memory Channels will be skipped. (See "Memory Channel Lockout" section on Page 24.)

Exmple 1:

When group number 2 is selected:

Exmple 2:

Group numbers 8 and 3 are selected and numbers on the Numeric keypad are pressed in that sequence.

4.To resume scan, press the SCAN key again.

5.To clear scanning, press the CLEAR key.

Note:

The R-5000 microprocessor remembers the various scan parameters that you have specified and will follow whatever you have entered the next time you press the SCAN key.

Example:

Previously programmed memory scan data was to scan Memory Channels 20-29 and 40-49.

To scan this same range again simply press the SCAN key.

The R-5000 will continue to execute scan according to the above parameter until you manually change the informa- tion. This saves a lot of key strokes if you always scan the same ranges, etc.

4-4-2. Program scan

In the program scan mode the R-5000 will scan from channel 8 to channel 9 of the current memory channel group. This allows you to program up to 10 different scan ranges; 18 — 19, 28 — 29, 38 — 39.... The program scan

step size is determined by the mode in channel 8 and the STEP key. To specify which group to scan press the M. IN key to enter the Memory Scroll mode. Select the desired memory channel group using any desired method, you can select any memory channel of the desired group. After the group has been specified press the CLEAR key to return to the VFO mode. Scan will begin at the frequency specified in memory X 8 and proceed up or down, depending on the frequency entered into channel X 9. Scan will go up if the frequency in X 9 is greater than X 8 and down if channel X 9 is less than X 8.
