REPEATER OPERATION
Amateur radio repeaters utilize separate transmitter and receiver sections. The transmitter frequency may be offset either above or below the receiver frequency according to repeater coordination conventions. Note: Repeater offsets are sometimes referred to as “splits”.
To select repeater offset frequency and direction:

1. Select VFO mode, select desired repeater output frequency and press the SHIFT key. Each time the SHIFT key is pressed the offset indicator will step cycle through the various offset options one at a time.
2. The current offset (usually 0.60) and the minus sign ( – ) will appear first on the LCD display panel indicating a minus offset of 0.60 MHz (600 kHz). In this position the desired offset frequency may be selected by rotating the main tuning dial in either direction. The DR-590T/E accepts offsets from 0.00 to 10.0 MHz in 5 kHz or 12.5 kHz steps
3. Press the microphone PTI switch to store the selected offset, the minus ( – ) shift and return to the selected repeater frequency.
4. Pressing the SHIFT key again will show the VFO frequency and the plus (+)offset indicator on the LCD display panel. Press the microphone PTI switch to store the frequency and the plus ( +) offset.
5. Pressing the SHIFT key again will show the VFO frequency but neither the minus ( – ) nor the plus ( +) offset direction indicator. In this mode the transmitter is not offset from the receiver frequen­cy indicating the simplex mode. The transmitter will transmit on the frequency to which the receiver (VFO) s set.

REVERSE (REV)
In some areas there may be repeaters operating on repeater frequency pairs the exact reverse of another repeater n the area. That is, the input of one repeater is the output frequency of the other and vice versa. The input and output frequencies of these repeaters are identical but reversed. To avoid the incon­ venience of reprogramming every time both repeat­ ers are in range the REV key allows instant reversal of the input and output frequencies and the offset direc­ tion. The REV function is also useful to check the repeater input and to determine if another station is within simplex range.
To activate the REV function:

1. Press the REV key. The repeater nput frequency and the opposite SHIFT ndicator will appear on the LCD display panel.
2. Press the REV key again to cancel the REV function.

AUTOPATCH OPERATION (DR-590E: Option)
Many repeaters offer a telephone link known as an autopatch allowing use of the DR-590T/E n much the same manner as a mobile or cellular telephone. The DTMF (Dual Tone Multi Frequency) key pad on the supplied microphone is used to activate an auto­ patch and other repeater user functions. The repeat­ er control operators or regular repeater users can advise how these functions are used.
Autodialer (DR-590E: Option)
This function is used to transmit a memorized DTMF code, such as a telephone number, up to 18 digits. The DR-590T/E has four autodialer memory chan­ nels in each band. It also has one memory channel in each band for receiving DTMF codes.
To Program The Autodialer: (DR-590E: Option)

1. Select desired band, select VFO mode then enter code C13 on the microphone DTM F pad. A chan­ nel number and flashing minus ( – ) sign will appear.
2. Select desired channel number using the MHz UP/DOWN switch on the main unit front panel. The C08/C09 DTMF pad codes cannot be used to change channel numbers while autodialer s being programmed. Each time the MHz UP/ DOWN switch s pressed the channel number will change upward from one to five and the flash­ ing minus ( – ) sign will be present. When channel 5 appears it will display a flashing letter· ‘o’ ‘. Chan­ nels one through four are transmit autodialer memory channels. Channel 5 is the DTMF moni­ tor channel.
3. Enter desired telephone number and any re­ quired codes such as A, B, C, D, * or # up to 18 digits. To store the number press the FUNC key or the microphone PTI switch.

ADDITIONAL FUNCTIONS AND OPERATIONS

Simultaneous Receiving And Full Duplex Operation
Among the many useful features of the DR-590T/E are the ability to receive on both bands at the same time and also to operate in the full duplex mode simi­ lar to a telephone where both parties can speak and listen simultaneously on two different channels.
Simultaneous Receive On Both Bands:

1. Simply select the desired receiving frequencies on each band. Ensure that the MUTE function is not active on either band.

Full Duplex Operation:

1. Select VFO and set desired frequency on each band. Either band may be used to transmit. The selected Main Band will be the transmitting band. The sub-band will be the receiving band. In this mode you speak on the Main Band and listen on the sub-band. Avoid repeater frequencies. Res­trict full duplex operation to establish simplex fre­quencies only.

ABX (Automatic Band Exchange)
This function automatically selects whichever band is active, hearing a signal, as the Main Band. For exam­ple, if VHF has been selected as the Main Band the ABX function will switch automatically to the UHF band if it becomes active and VHF is not receiving a
signal. UHF will remain the Main Band as long as it hears a signal then will switch back to the VHF band whether or not it is active. Likewise, if UHF is the Main Band ABX automatically switches to VHF ii it be­ comes active while UHF s quiet.
To Select The ABX Function:

1. Select VFO and set desired frequency on each band.
2. Press the FUNC key then the ABX key The ABX ndicator will appear on the LCD display panel and the ABX function becomes active.
3. If the microphone PTI switch is pressed while ABX has switched to the sub band the ABX lunetion is cancelled and the sub-band becomes the Main Band.
4. If a Priority function is active on the sub-band it will be nactive when ABX switches to the Main Band. Priority will resume when ABX returns to the subband.

MUTE
The MUTE function permits temporary silencing of either band.
To Mute Either Band:

1. Press the MUTE key repeatedly until the MUTE symbol on the LCD display panel appears over the band to be silenced.
2. To cancel MUTE press the MUTE key until the MUTE symbol disappears.

LOCK
This function prevents unintended function changes by ocking out all funct ons except the main POWER switch and the microphone PTI switch.
To Activate The LOCK Function:

1. Press the FUNC key then the LOCK key.
2. To cancel LOCK press the FUNC and LOCK keys again.

DIM (Dimmer)
The DIM function allows selection of two different LCD display panel brightness levels.
To Change LCD Brightness Level:

1. Press the FUNC key then the DIM key. Repeated pressing of these keys will raise and lower the brightness level.

CANCEL
Some mistaken operations may be corrected w th the CANCEL function.

1. When frequency is changed by mistake press the CANCEL key within live seconds and the previ­ous frequency will reappear on the LCD display.
2. If Memory Scan is started by mistake press the CANCEL key within live seconds. The former fre­quency will reappear on the LCD display panel.

DSQ (DTMF Squelch)
The DSQ is an abbreviated name of DTMF squelch and has the pager and code squelch functions. The DSQ requires the optional DTMF unit (EJ-BU) and a microphone remote control (EMS-3) with DTMF sup­plied for US version.
A. DESCRIPTION OF DSQ
The DSQ is divided into the pager and code squelch. The pager s divided nto the 3 groups. The LCD display as shown below:

Classification of code
The DSQ has three codes, namely the group code, self-station code, and remote station code. A pager consists of the combination of these three codes. Only the group code s used by the code squelch. Each code consists of three digits. The group code is the code of a group which one belongs to.
The self-station code is the code of its own The remote station code is the self-station code of a partner whom one is communicating or one wish­ es to communicate.
Code squelch
The code squelch allows the squelch to be opened when the received three-digit code agrees with its own group code. The same code is transmitted on transmission. This machine has three group codes. Comparison of agreement is performed to all three group codes. f either one of them agrees, the code s automatically selected.
Group paging
The type of group paging consists of the group code (3 digits), “ “, and self station (3 digits) (a total of 7 digits). When group paging is per­ formed, stations with the same group code can communicate each other. This machine has three group codes, making comparison of the received code and three codes for agreement. If either one of them agrees, the code is selected.
Private paging (individual paging)
The type of private paging consists of 7 digits, namely the remote station code (3 digits), “ “, and self-station code (3 digits). When private pag­ ng is made, the squelch of the station with the same self-station code as the remote station code which has been sent s opened for enabling com­ munication to be made.
In this machine, the squelch is opened when the received remote station code agrees with the self-station code owned by the self station. Also, the received self-station code is rewritten as the remote station code of self station.
Private paging within group
The type of private paging w thin a group con­ sists of 6 digits, namely the group code (3 digits), upper one digit of remote station code, ” “, and upper one digit of self-station code.
When private paging within group is performed, the squelch of a station having the same upper one digit as that of the received remote station code as the self-station code is opened, thus enabling communication to be made. In this machine. the group code enables auto­matic selection to be made. Being based on the received self-station code, the remote station code is rewritten by producing three digits, namely the self-station code which receives the code (1 digit), ” “, and ” “.
Automatic selection of DSQ mode
Whichever paging may be selected for the pager, the received type is used to judge the type of pag­ ng and to select the paging mode.
B. HOW TO SET DSQ CODE
The DSQ code consists of a total of 5 codes. namely 3 group codes, 1 self- station code, and 1 remote station code. The details of remote station code may change depending on communi­cation.
Paging of code setting mode
Set the VFO mode and then enter the ‘C10” from a microphone remote control. The frequency dis­play of main band blinks. Enter the NO. of code to be entered.
Self-station code: O
Group code: 1-3
Remote-station code: 4
The code NO. and the uppermost one digit of code at that time appear. Also, the remote station has the codes ndependently for VHF and UHF Set them as needed.
Code input
Enter the codes to be input in order. They are transmitted from the uppermost digit on trans­ mission.
Rotate the main dial counterclockwise for correct­ing halfway during input. Every time you reach the next detent position, you can go back to the previous code.
Blinking indicates the location of current entry. Rotate the main dial clockwise if you do not wish to change the code where LED is blinking. Every time you reach the next detent position, you can go to the next code.
When you complete entering up to three digits, you can go back to the VFO mode. When com­ pleting halfway during entry, press any key on the main unit. Then, you will go back to the VFO mode.
Cautions on code entry
On pager, the ” ” mark is used as a delimiter between codes. Thus, if you specify the ” ” mark at the uppermost position of self-station code, you cannot perform private paging within group.
Example: Group code: 123, self-station code: .oo, There s a private paging within group when the self-station code of remote station is equal to 345.

The ” #” s used as a wildcard. The wildcard allows the code to be judged to be in agreement unconditionally for that position. By using a wild· card, it becomes possible to perform the same operation as having a plurality of self- station codes or four or more group codes.
Example: hen 12 # s specified to the group code in the code squelch:

The wildcard temporarily changes the details on paging from the remote station.
When transmitting immediately after setting, the “12 #” is transmitted and only the station with the group code “12 # ” opens the squelch. The samei s true immediately after modifying the group code to “12 # “. Although the wildcard as the re­mote station code can be set, it may be rewritten depending on the DSQ mode so that the function s not activated.
C. SELECTION OF DSQ MODE
The DSO mode consists of the code squelch. group paging, private paging, and private paging within group. Three of them are automatically selected when paging is made.
Paging of selection mode
When the “C12” is entered from the ten-key pad of a microphone remote control n VFO or memory read, the “DSQ” of DSQ display blinks.
How to select
When you press the MHz [△] and [v’] keys, the DSO display changes. Select a desired mode (the commands of a remote controller “COS” and “C09” are also possible).

When the selection of DSQ mode is completed, press the [FUNC] key or PTI switch. Set the DSO mode and return to the previous mode. Select the “CO?” code by the remote controller to return to the previous mode.
Cautions on selecting DSQ mode
Codes which can be used differ depending on the DSO mode to be used. The group code and the remote station code are used in the code squelch group paging and private paging, respectively. When the DSO mode is modified, the mode may be changed so that a usable code may be selected.
No DSO mode can be selected in the ARM and call modes.
D. SELECTION OF DSQ CODE
The selection of DSQ code s imited by the DSQ mode. In the case of private paging, there s only one remote station so that the remote station is selected automatically. n other cases, since the group code is required, t needs to be selected from three group codes.
Paging of selection mode
When you enter the “C11” using a ten-key pad of a microphone remote control in either the VFO or memory mode, the code NO. selected at that time and the details appear at the frequency display position.
How to select
Press the MHz [6] and [v’] keys in the select on mode to allow the code to be changed. Select a desired code (the “COS” and “C09” of a remote controller commands are also possible).
Cautions on selecting DSQ code
When the DSO has been set, codes to be selected are limited.
When the group code is not needed, t s auto-matically selected. Select a group code when needed. You can select codes ndependently for VHF and UHF.

E. OPERATION OF CODE SQUELCH
The code squelch is used to open the squelch when performing communication using a three­ digit code and a group code s used. The code squech allows whether the received code agrees with the group code of self station to be judged. If they agree, the code s selected and the succeedingng communication is made.

When paging from the self station, select the code previously. When you use it along with the bell function, alarm and display will inform it on paging.
F. OPERATION OF PAGER
When either of three pagings of pager is set. the DSQ mode s selected in the paged code type.
Example: When private paging is set:

Select the code and mode when performing paging from the self station. When you use it along with the bell function, alarm and display inform it on paging.
