CHANNEL PROGRAMMING FUNCTIONS

Setting to the FREQ Mode

The FREQ MODE is the state in which the frequency can be changed using the rotary selector or the numeric keys.
To set your receiver to FREQ mode:

Confirm the display. If M is displayed, press CLEAR PROGRAM key.

(When ‘M’ is displayed, you are in the Channel Memory Mode. )

Use rotary selector to change the frequency up or down to confirm you are in FREQ Mode.

Changing the Frequency

There are three methods for changing the frequency, 1) using rotary elector, 2) using the 5 key or ENT key while the
FUNC key is pressed, and 3) using the numeric keys.
Before changing the frequency, confirm you are in FREQ Mode by pressing CLEAR PROGRAM key.

The Channel Memory Function

l Frequencies that are used frequently in the expanded Mode can be entered to channel memories. Up to 399

different frequency settings can be entered into channel memories.

l The Mode in which frequencies are entered to channel Memory or called from channel Memory is called the

Channel Memory Mode. When in this Mode, the „M“ indicator lights up in the display.

l The number of the channel Memory where a frequency is stored is called the Channel Memory Address.

Channel Memory Addresses are available from 001 to 399 .

l A Channel Memory Protect function ( 33) is provided to prevent changes in the contents of channel Memory or

clearing of channel Memory by mistake.

The following types of channels are provided for different purposes.

Search Band Channel Memories ( 32, 40)
Upper and lower limit frequencies of each band are entered into corresponding channel numbers. Up to 10
sets (20 frequencies) of upper/lower limit frequencies can be entered into these channel memories. These
frequencies have been preprogrammed in these channel memories at the factory, however, they are all
programmable.

Search Pass Memory

Frequencies entered in this channel Memory are automatically skipped when a search is in progress. When
there is a frequency that you do not want to receive, they can be entered into these Memory channels. Up to
80 frequencies can be entered in this channel Memory.
Priority Channel Memory ( 32)
One frequency which is most frequently used can be entered into this channel Memory. During SCAN, this
frequency is automatically monitored alternatively with frequencies in other channels. (Dual Watch, 46).

How to Store A Frequency into Channel Memory

Frequently used frequencies can be programmed into a channel Memory.

Set the unit in FREQ Mode by pressing CLEAR PROGRAM key.
Enter the frequency you want to program into a channel by using numeric and decimal keys.

(Illust. 17-1)

Hold down FUNC key and press CLEAR PROGRAM key.

(This activates the channel memory store state.) (Illust. 17-2)

key once again to program selected frequency into the indicated channel number or enter 3-digit channel
number that you wish to program into by using numeric keys.

(A high pitched beep is emitted, the frequency is entered into channel Memory and the receiver returns to the
FREQ Mode.)

Note:
l In Step 4, enter corresponding channel numbers if you wish to program the frequencies Search Band Channel

Memories. The corresponding channel numbers are 400 for 0-A and 401 for 0-b (Band „0“), 402 for 1-A and
402 for 1-b (Band „1“) and , ..., 418 for 9-A and 419 for 9-b. ( 40). Refer to page XXX for more details.

l When programming a frequency into Priority Channel Memory, use the Selector to display the Pri indicator or

enter 000 as channel number by using the numeric keys.

l In Step 4, if there is no vacant channel Memory address, the display shows „min -“.
