2.0 OPERATION

2.1 GENERAL INFORMATION

The TCR-SPK-DUALv2 can be used for operation once it has been installed, as described in

Section 3.

2.2 CONTROLS

The TCR-SPK-DUALv2 has an intuitive front panel with seven buttons, as shown in Table 2-1:

2.3 POWER ON, INITIALIZATION, AND SET UP

Pressing the front panel PWR pushbutton initiates a Power On Self-Test (POST) process, after

which the speaker is ready for operation.

Net A and Net B volume is adjusted using the A+/A- and B+/B- pushbuttons. The radio

volume control controls handset volume. Set Up is complete once the unit is powered on and

proper volume levels set.

NOTE: A minimum radio volume level, equivalent to that which can be heard on the standard

handset, is required for proper operation of the speaker's auto noise gating and AGC functions.

Ensure receiving radio is set to the proper minimum volume.

Power down (off/bypass) is accomplished by pressing and holding the PWR pushbutton for

greater than two seconds.

NOTE: Upon application of DC Power, the TCR-SPK-DUALv2 returns to its previous

operating state, including all settings.

2.4 PUSHBUTTON FUNCTIONS

PWR Pushbutton – Power On/Off - To turn the speaker on, press the PWR button

momentarily. The speaker will turn on, complete a post process, and is then ready for

operation in the same state as it was last powered off. The PWR button is backlit green when

the speaker is on. Press and hold the PWR button for more than two seconds to power down

the speaker. While off, handset and radio connections are straight pass-throughs enabling

communication using the handsets.

PWR Pushbutton – Brightness - To change the brightness of button backlighting, press the

PWR button momentarily. Each press will cycle through four levels of brightness: bright,

medium, medium-low, low.

EQ Pushbutton – Equalizer – Pressing the EQ button cycles equalizer settings for radio and

auxiliary audio, each with four factory settings: flat, low, mid, and high emphasis. Each

momentary press of the button results in a single tone that corresponds to the setting; a dual

tone indicates the factory setting. Settings for radio traffic are selected by pressing the EQ

button while receiving radio traffic or when no audio is playing. Settings for auxiliary audio

are selected by pressing the EQ button while playing auxiliary audio.

MUTE Pushbutton – Mute – Pressing the Mute button cycles mute conditions: Mute A/B,

Mute A, Mute B, Mute OFF. A single short tone indicates Mute OFF has been selected. The

Mute button is backlit green during any active mute condition.

NOTE: The mute button only mutes radio audio. Any audio played through the Aux port will

not be muted.

A+ Pushbutton – Volume – Momentary presses of the A+ button increases volume in ten

steps (audio logarithmic taper) with each increase indicated by a single short tone. A single

long tone indicates maximum volume has been selected. Holding the A+ button increases

volume through the steps continuously. The A+ button is backlit green anytime Net A is

muted. The A+ button will flash when Net A is muted and radio traffic is detected, alerting

the user to missed radio traffic.

A- Pushbutton – Volume – Momentary presses of the A- button decreases volume in ten

steps with each increase indicated by a single short tone. A single long tone indicates

minimum volume has been selected. Holding the A- button decreases volume through the

steps continuously.

B+ Pushbutton – Volume – Momentary presses of the B+ button increases volume in ten

steps (audio logarithmic taper) with each increase indicated by a single short tone. A single

long tone indicates maximum volume has been selected. Holding the B+ button increases

volume through the steps continuously. The B+ button is backlit green anytime Net B is

muted. The B+ button will flash when Net B is muted and radio traffic is detected, alerting the

user to missed radio traffic.

B- Pushbutton – Volume – Momentary presses of the B- button decreases volume in ten steps

with each increase indicated by a single short tone. A single long tone indicates minimum

volume has been selected. Holding the B- button decreases volume through the steps

continuously.

NOTE: The speaker volume buttons do not change auxiliary audio volume.

2.5 USB CHARGING PORT

The USB charging port is provided for charging USB devices only. The port provides 5 VDC

and up to 2.1A for charging.

2.6 AUXILIARY AUDIO PORT

The TCR-SPK-DUALv2 has a standard 3.5mm auxiliary audio-in port for audio playback.

Audio playback is automatically muted with incoming radio traffic or handset PTT. Auxiliary

audio volume is set by the auxiliary source. The audio playback function has a five second

delay after audio is started and after an automatic mute from incoming radio traffic or handset

PTT. After the five second delay, audio playback ramps back up to the auxiliary source

volume over a five second period.

2.7 HANDSET OPERATION

The handsets connected to the speaker control their respective radios. If single handset cables

(HDST A and HDST B) are used: the handset connected to HDST A will only control Radio

A, and; the handset connected to HDST B will only control Radio B. If dual handset cables

(MAIN A/B and AUX A/B) are used: the MAIN A and AUX A handsets control Radio A,

and; the MAIN B and AUX B handsets control Radio B.

3.0 INSTALLATION

3.1 PREPARATION FOR USE

After unpacking the system and inspecting for physical damage, select an appropriate location

for the speaker. Although the TCR-SPK-DUALv2 is weather-resistant, placing it in a location

where it is protected from rain, sunlight, and salt spray will increase its service life.

3.2 MOUNTING PROVISIONS

The TCR-SPK-DUALv2 can be mounted using the supplied mounting bracket with six #8

through holes, see Figure 3-1. Alternatively, the speaker can be flush mounted using four 8-32

x .25" deep tapped screw holes on the rear panel, see Figure 3-2. Ensure proper access to

connectors and clearance for cables.
