Additional Information

Internal Voice Operated Transmission (iVOX)/Voice Operated

Transmission (VOX)

The microphone detects if you are talking when using VOX/iVOX. If you are

talking, the radio triggers transmission automatically.

• When iVOX is displayed, the radio uses the built-in microphone to detect

your voice.

• When a VOX headset is connected to the radio, VOX is displayed and the

headset microphone is used to detect your voice.

You can turn off or select the following settings to select the

VOX/iVOX

sensitivity level.

Note: Pressing the PTT button cancels the VOX/iVOX transmission.

L3

High Sensitivity for quiet environments. Speaking softly is

enough to trigger VOX/iVOX transmission.

L2 Medium Sensitivity for most environments

L1

Low Sensitivity for noisy environments. You must speak up to

trigger VOX/iVOX transmission.

Call Tone

When you send a Call Tone, the receiving radio sounds a tone similar to

phone ringing tone.

Scan

Radio scans for voice activity by cycling through the channels. When signals

are detected, the signal is sent to the speaker. This feature allows you to find

which channel is being used by other groups and have heavy traffic. This

helps you to avoid the busy channels when deciding which channel to use for

your group.

Monitor

You can hear everything including noise on your current radio channel. This

feature allows you to monitor a channel for weak signals.

Roger Tone

This feature adds a beep to mark the end of a transmission when you release

the PTT button. When the receiver hears the roger tone, it is a confirmation

that complete message has been received.

Weatherproof

This radio is weatherproof to IP54 standards. The radio is resistant to

occasional splash of water only when the battery and connector covers are

sealed. Do not expose the radio to water for extended period of time. Do not

submerge the radio in water.

Installing and Charging the Battery

Turning your Radio On and Off

To turn the radio on or off, hold the Power/Menu button until the display turns

on or off.

Channel and Codes

• Set your radios with the same channel and code setting to enable communication

with other radios.

• The channel setting controls the radio frequency. To avoid jamming, select a

channel that is not used by others in your area. See table in Section 3, “Scan” for

more information on selecting unused channel.

• The code setting on the transmitting and receiving radios need to match, otherwise

the receiving radio blocks the received signal. This feature helps you to mute

unwanted voices from other radio users transmitting on your channel.

• When code is set to zero, radio does not block any signal and everything that is

picked up on the channel is sent to the speaker. Motorola Solutions recommends

setting your code to zero when using XT185/T72 with radios that do not support the

code feature. See Section 3, “Navigating the Menu Pages” for detailed instructions

on how to change settings.

• Channel and code settings can be copied from one radio to multiple radios

simultaneously with a shortcut feature called Easy Pairing. See table in Section 1,

“Easy Pairing” for instruction on how to copy channel and code settings.

2. Setting up Your Radio

1. Observe the polarity before installing the battery.

2. Charge the battery using the desktop charger or USB. Charging is

completed when the battery icon on the radio stops blinking. Charging

takes up to 8 hours.

Battery Information

The rated battery life is measured under industrial standard 5-5-90 duty cycle

under lab conditions. (5% of the time transmitting, 5% receiving with speaker

on, 90% waiting for incoming call.)

Caution:

Use only Motorola Solutions approved batteries. Risk of explosion if

the battery is replaced by an incorrect type.

Battery Capacity Maintenance

This radio comes equipped with a rechargeable Li-Ion battery. This battery

should be fully charged before initial use to ensure optimum capacity and

performance. Battery life is determined by several factors. Among the more

critical are the regular overcharge of batteries and the average depth of

discharge with each cycle. Typically, the greater the overcharge and the

deeper the average discharge, the fewer cycles a battery will last. For

example, a battery which is overcharged and discharged 100% several times

a day, lasts fewer cycles than a battery that receives less of an overcharge

and is discharged to 50% per day. Further, a battery which receives minimal

overcharging and averages only 25% discharge, lasts even longer.

Note: Connect the USB charger to a nearby and easily accessible wall power

outlet.

Note: Charge only Li-Ion type rechargeable batteries. Other types of

batteries may burst, causing personal injury or damage. Turn off radio before

charging.

Use the Menu button to scroll through the menu screen. Press PTT to exit any screen

and return to home screen.

Menu Screen

Use the or button to perform the following

actions:

Call Tone Start or stop Call Tone transmission.

Monitor Start or stop monitoring the air-wave. You can hear

signals transmitted on the channel setting of your radio.

If there is no signal, you can hear static.

Scan Start or stop scanning the air-wave. Radio scans all the

channels one after another. When a signal is detected,

you hear the signal on the speaker and the radio

displays the channel of the detected signal.

Adjust VOX To change the Voice Operated Transmission (VOX)

setting, select OFF or L1 to L3.

L3 being the most sensitive, use it in quiet

environments.

Adjust Roger Tone Enable or disable the roger tone. Roger tone is a beep

tone that you hear when PTT is released.
