GPH Plus Owner’s Manual 1

INTRODUCTION

CONGRATULATIONS, you now own a BK Radio GPH Plus radio. This enhanced GPH portable radio has 400 channels; whereas, the standard GPH series had a maximum of 240 channels. Like the standard GPH, the Plus radio has been designed to meet the tough requirements of today’s communications environment. Please take a moment to read the information in this manual so you can get optimum performance from your new radio.

FCC REQUIREMENTS

Your radio must be properly licensed by the Federal Communications

Commission prior to use. Your BK Radio dealer can assist you in meeting these requirements. Your dealer will program each radio with your authorized frequencies, signaling codes, etc., and will be there to meet your communications needs as your system expands.

SAFETY PRECAUTIONS

• Do not operate the transmitter in close proximity to blasting caps.

• Do not operate the radio in an explosive atmosphere (petroleum fuels, solvents, dust, etc.) unless your radio is an intrinsically safe model designed for such use.

RF ENERGY EXPOSURE AWARENESS AND

CONTROL INFORMATION, AND OPERATIONAL

INSTRUCTIONS FOR FCC OCCUPATIONAL USE

REQUIREMENTS

BEFORE USING YOUR PORTABLE 2-WAY RADIO,

READ THIS IMPORTANT RF ENERGY AWARENESS AND

CONTROL INFORMATION AND

OPERATIONAL INSTRUCTIONS TO ENSURE COMPLIANCE WITH

THE FCC’S RF EXPOSURE GUIDELINES.

NOTICE: This radio is intended for use in occupational/controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to meet FCC limits.

This radio device is NOT authorized for general population, consumer, or any other use.

This 2-way radio uses electromagnetic energy in the radio frequency

(RF) spectrum to provide communications between two or more users over a distance. It uses radio frequency (RF) energy or radio waves to send and receive calls. RF energy is one form of electromagnetic energy; other forms include electric power, radar, sunlight and x-rays.

RF energy, however, should not be confused with these other forms of electromagnetic energy, which when used improperly can cause biological damage. Very high levels of x-rays, for example, can damage tissues and genetic material. The energy levels associated with radio waves from portable 2-way radios, when properly used, are not great enough to cause biological damage.

Experts in science, engineering, medicine, health and industry work with organizations to develop standards for exposure to RF energy.

These standards provide recommended levels of RF exposure for both workers and the general public. These recommended RF exposure levels include substantial margins of protection. All 2-way radios marketed in North America are designed, manufactured and tested to ensure they meet government established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of 2-way radios.

These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it .

Please refer to the following WEBSITES for more information on what

RF energy exposure is and how to control your exposure to assure compliance with established RF exposure limits. http://www.fcc.gov/oet/rfsafety/rf-faqs.html http://www.osha.gov/SLTC/radiofrequencyradiation/index.html


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. Your BK Radio 2-way radio has a RF exposure product label. Also, your BK Radio owner’s and service manuals include information and operating instructions required to control your RF exposure and to satisfy compliance requirements.

COMPLIANCE WITH RF EXPOSURE STANDARDS

Your BK Radio 2-way radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) for human exposure to radio frequency electromagnetic energy.

This radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment at operating duty factors of up to 50% transmitting and is authorized by the FCC for occupational use only .

In terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or in Standby Mode. Note: The approved batteries supplied with this radio are rated for a 5-5-90 duty factor (5% talk-5% listen - 90% standby), even though this radio complies with the

FCC occupational RF exposure limits and may operate at duty factors of up to 50% talk.

Your BK Radio 2-way radio complies with the following RF energy exposure standards and guidelines:

•

United States Federal Communications Commission, Code of

Federal Regulations; 47 CFR §§ 1.1307, 1.1310, 2.1091 and

2.1093

•

American National Standards Institute (ANSI) / Institute of

Electrical and Electronic Engineers (IEEE) C95. 1-1992

•

Institute of Electrical and Electronic Engineers (IEEE) C95.1-

1999 Edition

INDUSTRY CANADA COMPLIANCE

This Class B digital apparatus complies with Canadian ICES-003. Cet appareil numerique de la classe B est conforme à la norme NMB-003

Canada.


RF EXPOSURE COMPLIANCE AND CONTROL GUIDELINES

AND OPERATING INSTRUCTIONS

To control your exposure and ensure compliance with the occupational/controlled environment exposure limits always adhere to the following procedures.

Guidelines:

•

Do not remove the RF Exposure Label from the device.

•

User awareness instructions must accompany device when transferred to other users.

•

Do not use this device if the operational requirements described herein are not met.

Operating Instructions:

•

Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push-To-Talk (PTT) button. To receive calls, release the PTT button. Transmitting 50% of the time, or less, is important because this radio generates measurable RF energy exposure only when transmitting (in terms of measuring for standards compliance).

•

Hold the radio in a vertical position in front of face with the microphone (and the other parts of the radio, including the antenna) at least one inch (2.5 cm) away from the nose. Keeping the radio at the proper distance is important because RF exposures decrease with distance from the antenna. Antenna should be kept away from eyes.

•

When worn on the body, always place the radio in a BK Radio approved clip, holder, holster, case, or body harness for this product.

Using approved body-worn accessories is important because the use of BK Radio or other manufacturer’s non-approved accessories may result in exposure levels which exceed the FCC’s occupational/controlled environment RF exposure limits.

•

If you are not using a body-worn accessory and are not using the radio in the intended use position in front of the face, then ensure the antenna and the radio are kept at least one inch (2.5 cm) from the body when transmitting. Keeping the radio at the proper distance is important because RF exposures decrease with increasing distance from the antenna.

•

Use only BK Radio approved supplied or replacement antennas, batteries, and accessories. Use of non-BK Radio approved antennas, batteries, and accessories may exceed the FCC RF exposure guidelines.

•

GROUP SCAN

Channels on each “Channel Scan List” in groups on the “Group Scan List” are scanned sequentially. The selected group is always scanned when Group Scan is enabled, even if that group is not on the Group Scan List.

When Group Scan is enabled, the following features are disabled:

• Dual Priority Scan

• User-Selected Channel Guard

• Nuisance Channel Delete


PRIORITY SCAN

PR SCN

LABEL 3

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. Priority Scan operates only while the radio is not transmitting and can be used in combination with scan operation.

When Switch C (Priority) is up, the display flashes SCN. If a message is received on a priority channel, the Priority Indicator lights, and the radio receiver locks onto that channel for the duration of the transmission, unless a higher priority channel interrupts.

Priority Scan can be used in combination with

Channel Guard with:

• Switch C (Priority) up

• The Squelch knob in the Channel Guard position (fully counterclockwise detent position) and

• The Priority Channel(s) programmed with

Channel Guard

If a message is received on a priority channel, the radio receiver locks on to the priority channel and checks to see if the proper Channel Guard value is present. If the signal contains the proper

Channel Guard value, the radio receives the message. Otherwise, the radio will re-check the channel every 4 seconds, until the activity on the channel ceases.

DUAL PRIORITY SCAN

In each group, up to two of the 16 channels can be designated as priority channels. These two,

PR1 and PR2, are periodically tested for activity, even if a different transmission is being listened to. Activity on PR2 preempts activity on any of the non-priority channels. Receptions on PR1 have priority over any other channel in the group, including PR2.


Either priority channel can be programmed as a fixed channel, tied to the Channel Selector knob, or programmed OFF. If the radio is programmed to transmit on the first priority channel, transmissions will occur on PR1 when operating in Priority Scan Mode.

If PR1 is a fixed channel, and the [PRI] key is not locked out, the user can move the channel selector to a new channel and press the [PRI] key to choose a new PR1 channel.

Dual Priority Scan is automatically disabled when Group Scan is on.

OLD-STYLE BK PRIORITY SCAN

The radio can be programmed with one of three

Priority Modes: A, B, or C. The table below shows how the priority channels and the transmit channels are selected in each mode.

To reply to a message on the priority channel, press the PTT switch and the radio will transmit on the priority channel. Once activity ceases on the priority channel, the radio returns to scan operation.

Priority Mode B

With Switch C (priority) up and Switch B (scan) down, the radio can receive on the knobselected channel while sampling the priority channel. If the priority channel becomes active, the Priority Indicator lights up. The radio changes to the priority channel and holds for the duration of the transmission.

To reply to a message on the priority channel, turn the Channel Selector knob to the priority channel, and then transmit.


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, turn the Channel Selector knob to the priority channel, and then transmit. Once activity has ceased on the priority channel, the radio returns to scan operation.

Priority Mode C

With Switch C (priority) up and Switch B (scan) down, the radio samples the fixed priority channel at the preset rate. If activity occurs on the priority channel, the radio 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. The radio transmits only on the priority channel when Switch C (priority) is up. Once activity has ceased on the priority channel, the radio returns to the receive channel on the Channel Selector knob.

Priority Mode C 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 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. The radio transmits only on the priority channel when Switch C (priority) is up. Once activity has ceased on the priority channel, the radio returns to scan operation.

CHANGE THE PRIORITY 1 CHANNEL

The fixed Priority 1 channel can be permanently set or can be changeable. If the radio has a changeable priority channel, use the following steps to make this change:


2. Turn the Channel Selector knob to the channel you want to enter as the new

Priority 1 channel.

NOTE: A channel can be the priority channel even if it is on the Scan

List. Due to multiple sampling of the same channel, however, maximum performance occurs when the priority channels are not on the Scan List.


USER SELECTED CHANNEL GUARD

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. The

OTHER OPERATIONAL FEATURES

The BK Radio GPH Plus is based on a microprocessor core that allows extra features and operational characteristics to be programmed into the radio. Your dealer can help define the best operational settings for your system and program them into the radio.

SCAN DELAY

Scan delay lets the radio receive a response to a transmission before scanning the other channels for activity. If you find that your scanner is restarting before message replies are received, you can ask your dealer to increase the scan delay time (0–7.5 seconds).

This timer is also used to allow for Talkback

Scan.

HI/LO POWER

Each channel in the radio can be individually programmed to always transmit in Low-Power

Mode, regardless of the position of the radio's top switch (or keypad [FCN] menu setting). If the programming for the channel allows high-power transmissions, the power level can be selected with a top switch or the keypad menu.

TIME-OUT TIMER

BUSY CHANNEL

The transmit Time-Out Timer limits the duration of calls and guards against accidentally locking on the transmitter and tying up the radio system.

Your dealer can program the duration of the

Time-Out Timer (15–225 seconds, or disabled).

If the radio has been programmed for Busy

Channel operation, it will operate in one of the following three Modes:

• Busy Channel Indication

• Busy Channel Lockout

• Busy Channel Lockout with Override

BUSY CHANNEL INDICATION

The yellow Busy Channel Indicator glows if there is carrier activity on the selected channel.

If the selected channel is a Channel Guard channel and the proper Channel Guard value is not detected, the Busy Channel Indicator remains on for the duration of the carrier activity and no message is heard. During Scan and

Priority Scan operation, the Busy Channel

Indicator glows when activity is detected on any channel on the Scan List.


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.

BUSY CHANNEL LOCKOUT

BUSY

The Busy Channel Lockout feature applies only to those channels programmed with a receive

Channel Guard value. When carrier activity is detected on the channel selected, the radio checks the receive Channel Guard value. If the proper Channel Guard value is present, the radio can transmit on that channel, even if the

Squelch knob is in the Channel Guard position.

If the radio detects an incorrect value or carrier activity only, the transmitter is disabled. If an attempt is made to transmit, an alert tone will be generated and the display will show the word

BUSY until the channel becomes available or the PTT switch is released, whether the Squelch knob is in or out of the Channel Guard detent.

Channels not programmed with a receive

Channel Guard value can be used to transmit regardless of carrier activity.

BUSY CHANNEL LOCKOUT WITH OVERRIDE

This mode operates in the same manner as

Busy Channel Lockout except that the user can override and transmit by turning the Squelch knob off the Channel Guard detent. The transmitter is locked out only if the Squelch knob is set to the Channel Guard detent.

CLONING PROCEDURE

Any “Master” radio (a GPH Plus with the desired radio frequencies and settings) is capable of transferring its program to another GPH Plus 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 GPH Plus radios and other BK Radio products.

NOTE: Some groups may be “locked” by PC programming to prevent them from being overwritten. Only “unlocked” groups will accept incoming clones.

Master

Clone

1. Make sure the battery packs for both radios are charged.

2. Attach the master switch end of the cloning cable to the side connector of the Master radio.

NOTE: One plug of the cloning cable has a push-button master switch. This plug must be attached to the

Master radio.

3. Turn on the Master radio.

4. Select the group to be cloned from the

Master radio.

5. Put the Master radio in Programming Mode by pressing and holding the master switch then pressing and holding the [FCN] key until the display shows ‘- - - ID.’ Enter the password of the selected group. The display shows ‘PRG CH 00.’

6. Review the values programmed in the radio by pressing the [FCN] or [ENT] key at each

CHXX prompt. Any required changes must be made now.

7. Connect the other plug of the cable to the side connector of the radio you want to clone.


8. Turn on the Clone and set it to the desired channel group.

SPECIAL CLONING INSTRUCTIONS

It is possible to 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 for sequential identification numbers used to identify a series of portables in a radio system.

Assuming that the frequencies,

Channel Guard values, and other CH 0 values are common for all radios in the system, but that the radio identification number should be unique to each radio, the following method can be used to clone additional radios for the system:

1. Program the Master with all frequencies,

Channel Guard values, and Channel 0 values that will be common to all radios.

2. Advance the display to show the ID number of the master (for example 100).

PRG ID

125

3. Press the [CLR] key; press 125. Do not press the [ENT] key. Now 125 is in temporary memory.

4. Press [*], connect the cloning cable to the

Clone radio, and download by pressing

[FCN]. ID number 125 is now stored in the permanent memory of the clone.

5. After downloading, press [CLR] on the

Master radio. Disconnect the Clone. The

Master radio display will show that 125 is still being held in the temporary memory of the master.

6. Press the [PRI] key. This will increment the

ID number one digit to 126.

NOTE: Any new number can be entered at this point by pressing [CLR] and using the keypad to enter the new number.

7. Press the [*] key. Connect the cloning cable to the next Clone and download by pressing

[FCN].

8. Any number of radios can be coded with different or sequential ID numbers using this technique. The ID number in the permanent memory of the master will remain unchanged at 100.


SCAN LIST CLONING

When a Master radio downloads to a Clone, the

Scan List is also transferred. See page 16 in this manual for selecting the Scan List.


BATTERY INSTALLATION AND REMOVAL

BK Radio battery packs are available in a variety of sizes and types for special applications. Rechargeable battery packs can be charged separately or while attached to a radio.

NOTE: For safety reasons, rechargeable battery packs are shipped uncharged or only partially charged. Therefore, a rechargeable battery pack should be properly charged before use.

INSTALLING THE BATTERY

1. Locate the center hub on the radio base and place it in the recess of the battery pack.

2. Position the battery pack at the 30° offset, seating the two metal studs in their recess.

3. Apply upward pressure to the pack while twisting the pack to its original position. The metal tab will click, locking the pack in position.

REMOVING THE BATTERY

1. Turn the radio off.

2. Push up the metal tab on the side of the case while twisting the battery pack approximately 30°.

3. Remove battery pack from the radio.

NOTE: All information programmed into the radio is maintained even when the battery pack is removed.

4. Periodically check the contacts on the battery pack for dirt that could prevent a good electrical contact with the charging base.

WARNING:

Explosion Hazard

Do not dispose a battery pack into a fire.

An explosion may occur.
