Safety and General Information

The following general safety precautions as would normally apply, should be observed during all phases of operation, service and repair of this equipment.

◇ This equipment should be serviced by qualified technicians only.

◇ Do not modify the radio for any reason.

◇ To avoid electromagnetic interference and/or compatibility conflicts, do not operate your radio when you are near 380V AC mains or above.

For vehicles with an air bag, do not place a repeater in the area over an air bag or in the air bag deployment area. Air bags inflate with great force. If a repeater is placed in the air bag deployment area and the air bag inflates, the radio may be propelled with great force and cause serious injury to occupants of the vehicle.

Turn off your repeater prior to entering any area with a potentially explosive atmosphere.

To avoid possible interference with blasting operations, turn off your radio when you are near electrical blasting caps, in a blasting area, or in areas posted: “Turn off two-way radio.” Obey all signs and instructions.

◇ Do not charge your back-up battery in a potentially explosive atmosphere

Do not expose the repeater to direct sunlight over a long time, nor place it close to heating source.

Do not place the repeater in excessively dusty, humid areas, nor on unstable surfaces

Connect to the lightning arrester prior to the antenna which is installed outside the building, and the chassis or equipment housing must be connected to an absolute earth ground, to minimize any possible shock hazard from lightning strike.

Please make sure no stress on the antenna joint during transportation or installation.

Caution:

This equipment generates, uses, and can radiate radio frequency energy and, if not installed or used in accordance with the owner’s manuals, can cause interference to radio communications.

Performance

The TR-800 is not a high performance repeater, unable to work with 100% continuous duty cycle, but able to withstand constant use. Equipped with switching power and repeater controller, the desktop repeater TR-800, is designed for indoor or fixed vehicle application where protection from the elements

(rain, humidity, etc) can be provided.

The fan is continuously variable, which minimizes noise in office or duty room environments while providing maximum cooling at elevated ambient temperatures or during heavy transmit duty cycles. It may have a surprisingly lower power slump when keyed for long periods in an office or shop environment.

Accessories

Your repeater comes with accessories including duplexer, microphone and antenna.

Duplexer

The duplexer allows the TR-800 receiver and transmitter to operate simultaneously in the same frequency band with a single antenna and feed line. Without the duplexer installed in the TR-800, it would be necessary to use two antennas spaced apart, with one connected to the receive radio and the other to the transmit radio. The positioning can vary from different models approved by HYT.

Microphone

The TR-800 can be used as base station in some occasion, where the microphone is required for dispatch application. There are two options available: palm microphone for mobile dispatch and desktop one for fixed application.

Antenna

When using two separate antennas, make sure enough physical spacing between transmit and receive antennas to yield at least 70dB isolation based on transmit and receive frequency separation. Generally, vertical spacing provides better isolation yet shorter physical spacing than horizontal spacing. HYT omni-directional antenna and mobile antenna are available.

Functions and Operations

Basic Operations

Short press the power switch to turn on the repeater; rotate the volume control knob clockwise to adjust the volume for a comfortable listening level. Press the “Up” or “Down” button to select a desired channel, then the radio operates as you set. Rotate the volume control knob fully counter-clockwise to minimize the volume, when no need to monitor activities on the channel.

To achieve the basic repeater functions, the radio must be in repeater setup, and operates in the uni-directional or bi-directional repeater mode.

Repeater Setup/Knockdown

Press the SETUP button located on the front panel to toggle between repeater setup and knockdown, with LED indications. While in setup state, both radios turn on at power-up; in knockdown state, only receive radio turns on at power up. There are three repeater types: base station, uni-directional and bi-directional in the repeater setup state. The repeater is initialized to base station mode when it toggles from setup to knockdown state. But in the knockdown state, the repeater works only similar to a mobile radio.

Operation Modes Toggle

The repeater can operates in modes including base station, uni-directional and bi-directional repeater mode. The logic control of operation mode can be achieved via the RPT and OPT buttons, with LED indications, shown as the following table:

Bi-directional Base station

(Forward) (Reverse)

√ × √ × RPT LED

OPT LED × √

“√” indicates LED lights, while “×” indicates LED goes out.

√ ×

Note: The repeater function is inactive while the repeater operated as base station, with slave radio as receiver, and main radio as transmitter. The front panel microphone PTT is disabled while

10

repeater operates in bi-directional repeater mode.

Repeater Hang Time

After receiving stops upon signal off, the transmitter remains transmitting for a programmed time period, which reduces delay on conversation due to the setup of repeater link. The repeater Hang Time is active when in forward directional repeater only.

Frequency Display

Short press the Monitor button displays the frequency in the turn of: slave radio Rx frequency, slave radio Tx frequency, main radio Rx frequency, main radio Tx frequency.

Monitor

If the Monitor function is set by your dealer, long press (over 1.2s) the programmed Monitor key while in receive mode, to hear activities on the current channel. The monitor function is inactive while in the bi-directional repeater mode. Two operation modes listed below are provided for you to choose via the programming software.

Hold down the Monitor key over 1.2s to open CTCSS/CDCSS signalling squelch. Release to close the signalling squelch.

Hold down the Monitor key over 1.2s to open carrier squelch; release to close the carrier squelch.

Scan

The Scan function is active while in the forward directional repeater mode only. Press the Scan button to initiate radio scan (if scan parameter is applicable). The Scan Interval Time and Dropout Delay Time are configurable via the programming software.

CTCSS/CDCSS

Set up talkgroups/users with unique CTCSS/CDCSS to prevent unwanted conversations on the same frequency. If CTCSS/CDCSS is set on the current channel, causes a CTCSS/CDCSS match to be required on an incoming call. If not set, the radio unmutes to all calls within the communication range on the current channel. Your dealer may preset CTCSS/CDCSS on certain channels.

11

Note: This feature does not mean that your conversation will not be heard by others.

Time-out TimerTOT

The feature allows for more efficient use of channels by limiting the maximum time of each transmission.

It protects the radio from damage caused by long time transmission.

Once a continuous transmission exceeds the preset time (15~1200s programmable), the transmission is automatically terminated
