NOTES: INTRODUCTION CONGRATULATIONS, you now own a BK Radio DPH APCO Project 25 digital radio. To meet backwards compatibility as defined by the APCO Project 25 standard, the DPH digital portable radio provides users the ability to interoperate with narrow or wide band analog channels as well as digital systems. Please take a moment to read the information in this manual so you can get optimum performance from your new radio.
DEFINITIONS AND ACRONYMS ANI CG CLR Cloning Automatic Numeric Identification Channel Guard Clear The process of copying data from one radio, called “master,” to other radios, called “slaves” or “clones.” Channel Guard A subaudible tone, a code (analog) or a Network Access Code (digital) for selective listening and receiving. Detent The click/hesitation you feel as you turn a knob from one position to another.
SCAN LIST CLONING FEDERAL COMMUNICATIONS COMMISSION REGULATIONS The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for portable 2-way radios before they can be marketed in the U.S. When 2-way radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a product label directing users to specific user awareness information.
SPECIAL CLONING INSTRUCTIONS You can change Channel 0 values on the master radio, hold them in a temporary memory, and download them to the clone without actually entering them into the permanent memory of the master. This is convenient if sequential identification numbers are used to identify a series of portables in a radio system.

CLONING PROCEDURE BASIC OPERATION Any “master” radio (a DPH with the desired radio frequencies and settings) is capable of transferring its program to another DPH or “slave” radio. The radio receiving the program is also referred to as the “clone.” The LAA0700 cloning cable will be required in the following procedure. Contact your BK Radio dealer for information on cloning between DPH radios and other BK Radio products. RECEIVE 1. TURN POWER ON by turning the Volume knob clockwise.
DISPLAY BACKLIGHTING CHANNEL GUARD OPERATION Channel Guard allows one radio or group of radios to be selectively called within a system. On digital channels, if the channel’s Squelch Mode is set to ‘Normal’, all signals with matching Network Access Codes (NACs) will be received. If the Squelch Mode is set to ‘Selective’, the signal must have a matching NAC and Talk Group ID, or a matching NAC and Unit-To-Unit ID to be received.
ALPHANUMERIC DISPLAY MIXED MODE OPERATION DPH radios have a slide-out keypad/display cover. To remove or install the cover, turn off the radio and remove the battery (see Battery Installation and Removal, page 39). The Alphanumeric Display can be programmed to operate in 7-Segment Mode.
When scanning or priority scanning Channel Guard channels with the Squelch knob in the Channel Guard position and activity has been detected, the Busy Channel Indicator glows for the time period necessary to determine if the proper Channel Guard value has been received. This will cause the Busy Channel Indicator to flash at various rates. CHANNEL GROUPS 6 5 4 3 9 10 11 12 13 14 2 1 16 15 7 8 Radios are separated into groups of 16 channels each.
ANI ENCODING (Analog Mode Only) 1 2 3 FCN 4 5 6 PRI 7 8 9 ENT * 0 # CLR ANI encoding (Automatic Numeric Identification), if enabled, transmits a sequence of DTMF tones each time you press the PTT switch. You will hear a sidetone. Your dealer can program the ANI number to be sent. If DTMF and ANI are both enabled, the ANI tone sequence is transmitted only after the [ENT] key is pressed while the PTT switch is activated. You will hear a sidetone.
PROGRAMMABLE TOP SWITCHES/ FUNCTION MENU OTHER OPERATIONAL FEATURES The following functions can be assigned to the three top switches or the keypad FCN key menu: Scan TX Digital Priority Scan FUNCTION FCN Key Menu Label Low Power Select LO POR Channel Scan ChN SCN Priority Scan PRI SCN Repeater Talk Around TRN DIR Group Scan GRP SCN Transmit Digital TX DIG Your dealer can also assign more than one function to the same top switch.
KEYPAD LOCK USER SELECTED CHANNEL GUARD To lock/unlock the keypad, press and hold the [FCN] key. When the radio is being programmed with transmit and receive frequencies for each channel, a receive Channel Guard value and a transmit Channel Guard value can also be assigned to each channel. If User Channel Guard Selection is enabled, the Channel Guard values for any channel can be copied to another channel in the radio.
SCAN CHANNEL GUARD CHANNELS EMERGENCY CALL 1. SLIDE SWITCH B (SCAN) UP. 2. TURN THE COMPLETELY SQUELCH KNOB COUNTERCLOCKWISE, past the detent, to the Channel Guard position. When a signal is detected, scanning stops while the radio checks for the proper Channel Guard value. If the signal contains the proper Channel Guard value, the radio receives the message. Otherwise, the radio resumes scanning immediately.
PROGRAMMING A LABEL TALKBACK SCAN Press the [CLR] key. The display becomes blank. If your radio is programmed for Talkback Scan, press PTT while a channel is active or while scan delay time remains. You will be responding on the transmit frequency of the received channel. Press number keys to enter 0-9 in positions 17. The digits start in position 7, then move left. 1. Press the [#] key to toggle a decimal on or off to the right of the character in position 7.
When Group Scan is enabled, the following features are disabled: • Priority Scan • Dual Priority Scan • User-Selected Channel Guard 1 2 3 FCN • Nuisance Channel Delete 4 5 6 PRI 7 8 9 ENT * 0 # CLR PRIORITY SCAN Priority Scan enables the radio to receive on any channel while monitoring for a message on the designated priority channel(s). The radio samples each priority channel at a preset rate (.25-2.0 seconds) regardless of activity on any other channel.
INITIATING A UNIT-TO-UNIT CALL 1 2 3 FCN 4 5 6 PRI 7 8 9 ENT * 0 # CLR LABEL Last Active Was Unit On Call List ID 145 Last Active Was Unit Not On Call List ID < Prompt For Manual ID Entry DUAL PRIORITY SCAN To initiate a Unit-To-Unit call, press the [*] key to enter Unit-To-Unit Mode. The label of the last active (called or received) ID will appear on the display.
WHICH MODE IS INSTALLED? RX If the radio has a display and keypad, follow these steps to determine which Priority Mode is programmed: CH ID Incoming Group Call 5 1. SLIDE SWITCHES B (SCAN) AND C (PRIORITY) DOWN. 2. TURN THE CHANNEL SELECTOR KNOB, stopping at each channel to view the LCD display. Does PR appear in the display? RX CH 5 Incoming Analog Call Yes Turn channel knob to different channel.
Priority Mode A With Scan UNIT-TO-UNIT CALL 1 2 3 FCN 4 5 6 PRI 7 8 9 ENT * 0 # CLR ID 785 Radio Unit ID P25 Unit IDs allow for Unit-To-Unit calls when the radio is operating in Digital Mode. To view the radio’s ID, press and hold the [*] key while not in Unit-To-Unit Mode. (UnitTo-Unit Mode is indicated by a phone icon in the upper right corner of the display). Channels programmed for analog only operation will not be able to transmit or receive Unit-To-Unit calls.
Priority Mode B with Scan With Switches B (scan) and C (priority) up, the radio scans until it locks on to an active channel. The radio continues to sample the priority channel while listening to the active scan channel. If activity occurs on the priority channel, the radio overrides the active scan channel, changes to the priority channel, and holds for the duration of the transmission. To reply to a message on the priority channel, press the PTT switch.
