PRO850 OPERATION............................................................................................................9

The HME PRO850 is Type Accepted under Part 74 of the United States Federal Communications Commission (FCC) Code of Federal Regulations governing general purpose applications. The system requires an FCC station license if operated within the United States or its possessions. Licensing of this equipment is the User’s responsibility. Licensability depends on the User’s classification, equipment application and frequency selected. The user should contact the appropriate telecommunications authority for any desired clarification.

CAUTION: Changes or modifications made by the user could void the user’s authority to operate

PRO850 equipment.

FCC LICENSING

MANDATORY SAFETY INSTRUCTIONS

FOR BASE STATION INSTALLERS AND USERS

1. Use only manufacturer or dealer supplied antennas. Antenna minimum safe distance, as calculated

from FCC requirements, is 4.8cm. However, the FCC default for minimum safe distance is 20cm. Antenna gain: zero dBi referenced to a monopole.

2. The Federal Communications Commission has adopted a safety standard for human exposure to RF

(Radio Frequency) energy, which is below the OSHA (Occupational Safety and Health Act) limits.

3. To comply with current FCC RF exposure limits, the antenna must be installed at or exceeding the

minimum safe distance described here, and in accordance with the requirements of the antenna manufacturer or supplier.

4. Antenna substitution: Do not substitute any antenna for the one supplied by or recommended by the

manufacturer or radio dealer. You may be exposing person or persons to harmful radio frequency radiation. You may contact your radio dealer or the manufacturer for further instructions.

5. WARNING: Maintain a separation distance from the antenna to person(s) of at least 20cm.

You, as the qualified end-user of this radio device must control the exposure conditions of bystanders to ensure the minimum separation distance (above) is maintained between the antenna and nearby persons for satisfying RF exposure compliance.

Operation of this transmitter must satisfy the requirements of the General Population/Uncontrolled Exposure Environment for work-related use. Transmit only when person(s) are at least the minimum distance from the properly installed, externally mounted antenna.

SECTION 1. INTRODUCTION

PRO850 equipment operates in the UHF band from 470 MHz to 740 Hz in 18 MHz subsets. Transmitters and receivers operate in different, non-adjacent 18 MHz bands. Synthesized frequencies can be selected in 25 kHz increments over each 18 MHz band, for 720 transmit and 720 different receive frequencies.

Base stations can be configured with up to four receivers and two transmitters, supporting up to four Beltpacs in full-time transmit, full-duplex operation. Two or three base stations interconnected can support up to twelve beltpacs operating at once. The channel lockout feature supports several beltpacs sharing the same frequency. In this mode, one beltpac user on a shared frequency can transmit at a time. If another user is already transmitting on that frequency, a “busy” signal will be heard. A total of sixteen beltpacs can be used with a system.

A feature can be selected that scans through all available intermodulation-free frequency groups to automatically configure the system for the best available set of frequencies. Specified frequencies can be saved for quick recall.

The PRO850 can be configured for fixed power output levels or automated output power control. With the automated feature selected, the PRO850 senses how far a beltpac is from the base station and automatically determines at what power level the beltpac should be operating, eliminating base station receiver overload and increasing beltpac battery life.

Two hardwired intercom channels provide simultaneous 2-wire and 4-wire operation.

The base station headset interface automatically detects and accommodates dynamic or electret microphones. It provides direct access to intercom channels 1 and 2, beltpacs only or all channels.

Any beltpac button can be configured to activate the base paging relay and, at the same time, audio is routed to the paging output.

The base can be configured to initiate an alert for various conditions, including low battery condition or button press from a beltpac.

The PRO850 is fully compatible with RTS

With the provided PC850 software, the base station and beltpacs can be configured on a PC, and configuration settings can be saved to files. An RS-232 serial port and a USB port on the rear panel of the base station provide PC interface capability. Beltpacs can also be configured using a Palm-OS PDA with the optional PDA850 software.

The base station can operate from a standard 12-14VDC power source or from an external DC source such as a vehicle electrical system for mobile operation.

BASE STATION OPERATION

Uses of Front Panel Controls, Indicators and Connectors

1 2 3 4

1. Power Switch

Press the upper part of the switch to turn the power on. A red light on the switch will be lit when the base station power is on. Press the lower part of the switch to turn the power off. The red light will go off.

2. Beltpac Configuration Connector

After beltpac configuration settings have been made in the base station, plug one end of the enclosed RJ10 interconnect cable into this connector, and plug the other end into the RMT receptacle on the bottom of a beltpac to upload the settings into the beltpac. Repeat this to upload settings for each beltpac to be used.

CAUTION: Be sure not to turn the beltpac power off and on again while it is connected to the base station. If this does happen, unplug the cable and cycle the beltpac power again.

3. Wired Status Indicator Ligh t s CH1 and CH2 lights:

If a 4-wire intercom channel is enabled, the respective CH1/CH2 light will blink when the PRO850 is sending audio on that intercom line. If a 2-wire interface channel is enabled, the respective CH1/CH2 light will be on steady when the user is not talking. When the user is talking, the light will be on steady and blinking off.

AUX light:

The auxiliary light indicates use of the ISO+ mode. When ISO+ is on, the AUX light will be on steady. When someone is talking on the ISO channel, the light will be on steady and blinking off.

4. Receiver Status Indicators and Buttons RECEIVER STATUS lights 1 – 4:

Steady red if the respective receiver squelch is turned down, or if it is receiving a signal (squelch is open). Blinking amber when the respective receiver is receiving status update from a beltpac. Steady green when the beltpac user is talking through the receiver. Blinking red or green if the beltpac being received has a low battery condition.

RECEIVER QUICK MENU buttons 1 – 4:

When pressed, squelch and audio controls for the respective receiver are provided immediately on the

display screen.

5. Local Headset Connector and Controls

Plug your local headset connector into the receptacle at the right end of the PRO850 front panel. Use the SELECT button to choose communication channels CH1, CH2, CH1 and CH2 together, or ISO. The respective indicator light above the button will remain lit for the selection you make. Press and release the TALK button quickly to “latch on” for open communication. Press and release the button again quickly to “latch off.” Press and hold the TALK button for more than one second for momentary communication. In this mode, the selected channel will remain open only as long as you are pressing the TALK button.
