Software Specification
Basic Operation
Short press the Power Switch/Volume Control knob to power on the repeater; rotate the Volume
Control knob clockwise to adjust the volume to a comfortable level. Press the Up or Dn button to select
a desired channel. Then the repeater will operate as you set.
To achieve basic repeater functions, the radio must be in setup mode and operate in forward, reverse or
bi-directional repeater mode.
Repeater Hang Time
When the repeater stops receiving due to signal disappearance, the transmitter will keep transmitting for
a programmed time period. In this way, repeated startup of the repeater link is prevented when the PTT
key is frequently pressed. The Repeater Hang Time can only be activated in forward directional repeater
mode.
Display Frequency
Short press the Moni button to display Rx frequency of slave radio, Tx frequency of slave radio, Rx
frequency of master radio, Tx frequency of master radio by turn.
Monitor
If the Monitor function is programmed by your dealer, long press (more than 1.2s) the Moni button to
listen in activities on the current channel. The Monitor function is disabled in bi-directional repeater mode.
Two operation modes listed below are provided for you to choose via the programming software.
Note: In knockdown state, the Monitor function is disabled.
A. Signaling Off-Momentary
Hold down the Moni button to open the CTCSS/CDCSS, DTMF/2-Tone/5-Tone signaling squelch;
release it to close the signaling squelch.
B. Carrier Squelch -Momentary
Hold down the Moni button to open the squelch; release it to close the squelch.
Scan
The Scan function can only be activated in forward directional repeater mode. Press the Scan button to
initiate repeater scan (if scan parameter is applicable). The Scan Gap Time and Dropout Delay Time are
configurable via the programming software.
Note: The AUX4/5 MUST be programmed to Rx Carrier/Rx Tone/Decode Output Control to allow the
repeater to land on an active channel when an eligible call is received.

TR-800 Service Manual

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, a CTCSS/CDCSS matching will 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.
Note: This feature does not mean that your conversation will not be heard by others.
Time-out Timer (TOT)
The feature allows 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 to1200s programmable), the transmission will be automatically terminated
and an alert tone will be heard. The alert tone ceases upon the release of the PTT key.
Selectable Squelch Level (SQL)
Squelch levels are selectable (0 to 9) via the programming software.
Voice Compandor/Scrambler
The Voice Compandor/Scrambler feature may be enabled and disabled via the programming software.
The Emphasis/De-emphasis function needs to be disabled while the Scrambler feature is enabled, and
enabled while the Scrambler feature is disabled.
High/Medium/Low Power Programmable
High/Medium/Low power is selectable via the programming software.
Programmable Channel Spacing
Wide/narrow channel spacing is selectable via the programming software.

Repeater Setup/Knockdown
Press the SETUP button located on the front panel to toggle between repeater setup and knockdown,
with LED indications. The master radio is on in setup mode, and off in knockdown mode. There are 4
repeater modes in setup mode: base station, forward directional repeater, reverse directional repeater
and bi-directional. The repeater is initialized to base station mode when it toggles from knockdown to
setup state. But in knockdown mode, the repeater works merely as a receiver.
In base station mode, the repeater function is disabled, with the slave radio used as a receiver and the
master radio used as a transmitter. In bi-directional repeater mode, the front panel PTT is disabled.
The repeater setup/knockdown mode will be recorded when the repeater is restarted. For example, if the
repeater operates in forward directional mode, it will still operate in this mode after re-started.
PC Programming Mode
Connect the PC to the repeater via a programming cable. Data can be transferred from the PC to the
repeater and saved in the repeater memory. The repeater LCD will display “PROGRAMMING” when the
PC is reading/writing data from/into the radio. The LED flashes red, indicating the master radio is being
programmed; then the LED flashes green, indicating the slave radio is being programmed. The repeater
will be automatically reset after programming.

Programming Guide
Overview
This section describes programming and setup of the TM-800 radio and the front panel controller for use
in both uni-directional and bi-directional repeater configurations. In the uni-directional repeater
configuration, one radio operates as the receiver of the repeater and the other radio operates as the
transmitter of the repeater. In the bi-directional repeater configuration, each radio can receive or transmit.
However, the radio that is connected to J0102-Main will be referred to as the “master radio’ and the radio
that is connected to J0104-Slave will be referred to as the “slave radio”. See the “Repeater
Communication Interface & Display Unit” section for additional information.
