IINNTTRROODDUUCCTTIIOONN

This manual describes how to use the EDACS M-RK II Scan Portable Radio. The M-RK II Scan is a synthesized, microproces sor-based, high performance portable FM radio providing reliable two-way communications in both the Enhanced Digital Access Communications System (EDACS) trunking environment and conventional communication systems.

In the EDACS or trunked system mode, the user selects a communications system and group. In this mode, channel selec tion is transparent to the user and is controlled via digital communication with the system controller. This provides ad vanced programmable features and fast access to communica tion channels.

In the conventional mode, the user selects a channel and

directly communicates on that channel. In this mode, a system refers to a set of channels. A channel is a transmit/receive radio frequency pair.

The exact operation of the radio will depend on the operating mode, the radio’s programming, and the particular radio system. Most features described in this manual may be enabled or dis abled through programming. Consult the system administrator for the particular features that are programmed into the M-RK II Scan.

UUSSEER R IINNTTEERRFFAACCEE

The M-RK II Scan operating controls are located on the radio’s front, top and left panels. A 6-button keypad, liquid crystal display (LCD) for radio status information, microphone and speaker are on the front panel. The top panel houses a rotary SYSTEM/GROUP/CHANNEL knob, POWER ONOFF/VOLUME control knob and a protected red EMERGENCY button. An OPTION button, CLEAR/MONITOR button and the Push-To-Talk (PTT) button are all located on the left side panel. The Universal Device Connector (UDC) is located on the right panel and is used while programming the radio and for accessory connection.

The keypad is used for activation of various EDACS or con ventional features such as menu selection or scan operations.

The display has two, eight-alphanumeric-character lines used to show the operational mode of the radio. 15 status indicators, used to indicate various operating conditions such as transmitter on, channel busy, scanning, or low battery, are located above and to the right side of the character lines within the display. A back light illuminates the display and the keypad for nighttime use.

UUNNIIVVEERRSSAAL L DDEEVVIICCE E CCOONNNNEECCTTOOR R ((UUDDCC))

The Universal Device Connector (UDC) provides connections for external accessories such as a headset or a speaker-micro phone. When the radio is locked in a vehicular charger/repeater the UDC provides the audio and control connections between the radio and the vehicular charger/repeater. The UDC is also used to program and service the radio.

AALLEERRT T TTOONNEESS

The M-RK II Scan radio also provides audible alert tones or "beeps" to indicate the various operating conditions. These alert tones can be enabled or disabled through programming.

2211

CCaall ll OOrriiggiinnaattee

A short mid-pitched alert tone sounds after keying the radio (Push-To-Talk button is pressed). This indicates the radio has been assigned a working channel or that the radio is trans mitting on a conventional channel and voice communication may begin immediately. In conventional mode, this tone may be de layed after the PTT button is pressed due to GE-STAR signalling (if enabled through programming).

AAuuttookkeey y ((TTrruunnkkeed d MMoodde e OOnnllyy))

After being placed in queue or releasing the PTT button prior to a working channel assignment, the site calls the radio when a channel becomes available. At this point, the radio automatically keys the transmitter (autokey) for a short period to hold the channel. The radio sounds a mid-pitched tone when it is clear to talk; immediately press the PTT button to keep the assigned

channel.

CCaall ll QQuueeuueed d ((TTrruunnkkeed d MMoodde e OOnnllyy))

A high-pitched tone after pressing the PTT button indicates the system has placed the call request in the queue. The receiv ing unit(s) also hear the tones, indicating they will receive a call shortly. If the the PTT button is released, the radio will autokey whenever a channel becomes available (see Autokey).

SSyysstteem m BBuussy y ((TTrruunnkkeed d MMoodde e OOnnllyy))

Three low-pitched beeps will be heard if the radio is keyed when the system is busy, if no channels are available for sending

the message, if the call queue is full, or if an individual call is being

2222

attempted to a radio that is transmitting. Releasing the PTT button and re-keying initiates a new channel request.

CCaall ll DDeenniieed d ((TTrruunnkkeed d MMoodde e OOnnllyy))

If the radio is keyed and a low pitched tone is heard then the

radio is not authorized on the system that has been selected.

CCaarrrriieer r CCoonnttrrool l TTiimmeerr

If the programmed time for continuous transmission is ex ceeded, five short high-pitched warning tones followed by a long low-pitched tone will be heard. The transmitter will shut down shortly after hearing the alert, interrupting communications. Release and re-key the PTT button to maintain communications. This will reset the carrier control timer and turn the transmitter back on.

LLoow w BBaatttteerry y WWaarrnniinngg

A low-pitched tone is heard and comes on indicating that the battery voltage is low. The radio will continue to receive and transmit.

LLoow w BBaatttteerry y AAlleerrt t ((TTrraannssmmiit t LLoocckkoouutt))

If the radio is keyed and a low-pitched tone or two tones repeated until PTT or CLEAR button is pressed (either condition is pre-programmable) is heard and LOW BATT is displayed, the battery is discharged and the radio will not transmit. The radio will still be able to receive calls until the battery is discharged beyond the point of operation, after which the battery will need to be recharged to resume normal operation.

BBAATT

2233

KKeey y PPrreess ss AAlleerrtt

A short tone or "beep" sounds to indicate a key has been pressed. A short low-pitched tone indicates no action was taken because the key is not active in the current mode.

OOPPEERRAATTIIOONN

TTUURRNNIINNG G OON N TTHHE E RRAADDIIOO

Rotate the POWER ON-OFF/VOLUME knob clockwise, out of detent to turn the radio on. (Ensure the antenna and battery pack are properly connected prior to power on.) A short beep (if enabled through programming) indicates the radio is ready for operation. The display indicates, if programmed, the last se lected system name on line one and the last selected group or channel name on line two.

In the EDACS trunked environment, upon acquisition of the control channel, will come on. If communication with the system’s control channel cannot be established, will not turn on. This may occur if, for example, the radio is out of range of the trunking site. It may be necessary to move to another location or select another trunking system to reestablish the control channel link for trunked mode operations.

SSEELLEECCTTIIOON N MMOODDE E RRUULLEESS

Many operations require selection from a list such as sys tem, group or phone number. This selection process is handled in the same manner for all lists. the CLEAR/MONITOR button are used during the selection process. The following example systems list is used to explain the process:

2244

,,.,m, o

SSVVCC

, and

3 EAST

4 WEST

After entering a selection mode, the following generic dis

play format will appear.

Line one shows the currently selected item name (XXXXXXXX) from the list. Line two indicates the list (YYY) that the selection is to be made from and the number of the selected

item (ZZZ) within the list. (In some cases the information on lines 1 and 2 will be the opposite of this example.) If SYSTEM 2 is the current selection, the display appears as follows:

Line one contains the current system name, two,

SSYYS S = = 22

, indicates that selection is from the system list

SSOOUUTTHH

, and line

and it is the second system within the list.

A new system from the list is selected by using

to scroll through the list in increasing and decreasing

order respectively. In the previous example, pressing

and

lects the EAST system as shown in the next display.

2255

The radio may be programmed to wrap around from one end

of a list to the other end or to stop at the ends.

To exit the selection mode, press the CLEAR/MONITOR but

ton or wait for the timeout.

MMEENNUU

The menu function accesses features that are not available directly from the keypad. The order and specific number of menu items available is configurable through programming. Upon radio power up, the menu item that is at the beginning of the menu list will always be displayed first. Subsequent access to the menu function will return the last menu item that was shown in the display. To enter the menu mode, press

m,,,.

, and the CLEAR/MONITOR button are used

during the selection process. All of the selection mode rules previously detailed apply to the menu item selection process

with the exception of direct access. The radio will continue to receive and transmit normally while in the menu function.

NNOOTTEE

While in system, group or channel selection mode, the radio continues to receive calls normally and continues scanning if it is enabled. If a call is received during the selection mode process the radio will return to the normal receive mode display. Continuing with the selection process will return the display to the same point in the selection process if the selection mode time out has not yet expired. Any press of the PTT button during the selection mode process will initi

ate transmission and exit the selection mode.
