Additional Information
Internal Voice Operated Transmission (iVOX)/Voice Operated Transmission
(VOX)
The microphone detects if you are talking when using VOX. 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 sensitivity level.
L3| High Sensitivity for quiet environments. Speaking softly is enough to
trigger VOX transmission.
---|---
L2| Medium Sensitivity for most environments
L1| Low Sensitivity for noisy environments. You must speak up to trigger VOX
transmission.
Note: Pressing the PTT button cancels the VOX transmission.
Setting up Your Radio
Installing and Charging the Battery
- Observe the polarity before installing the battery.
- 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.
Note: Connect the USB charger to a nearby and easily accessible wall power outlet.
Inserting and Removing Belt Clip
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 set to enable communication with other radios.
-
The H/L (High/Low) icon is part of the Channel Number. Ensure all radios in your group show the same H/L icon.
-
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 an unused channel.
-
The code settings 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 the code is set to zero, the 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 T38 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, “EZ-Pairing” for instructions on how to copy channel and code settings.
Transmission Power
- In some countries, different powers are allowed for different channels. The H/L icon indicates if the current channel is a High or Low power channel. Motorola Solutions
recommends you use high-power channels for more reliable communications. Select low power channels only when your radios are not far from each other and you want to maximize the battery life.
Navigating the Menu Pages
Use the Menu button to scroll through the menu screen. Press PTT to exit any screen and return to the home screen.
Menu Screen| Use the button to perform the
following actions:
---|---
Call Tone
| Start or stop Call Tone transmission.
Monitor
MON| Start or stop condoning the air-wave. You can hear signals
transmitted on the channel setting of your radio. If there is no signal, you
can hear static.
Press the button to monitor and release to stop. After a few seconds of monitoring. you hear a beep sound. After the beep sound, the radio continues to monitor even if you release the button. To stop monitoring, press again.
Scan
| Start or stop scanning the air-wave. The 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
VOX /IVOX| To change the Voice Operated Transmission (VOX) setting,
select OFF an L1 to L3. L3 being the most sensitive, use it in quiet
environments.
Adjust Roger Tone| Enable or disable the roger tone. Roger’s tone is a beep
tone that you hear when PTT is released.
Channel ( Channel number blinks )| Change the radio channel setting.
Adjust Code
(Code number blinks )| Change the radio code setting.
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 the
speaker on, 90% waiting for an incoming call.)
Battery Capacity Maintenance
The T38 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 that 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 that receives minimal
overcharging and averages only 25% discharge, lasts even longer.
Push-to-Talk Time-out Timer
To avoid air-wave traffic congestion, transmission ends after one minute even
if the PTT button is still pressed. To reset the timer, release the
PTT button briefly.
Using Your Radio
Talking/Transmitting
- Press and hold the PTT button, then start talking into the microphone.
- Release the PTT button to stop transmission.
Note: Do not press the PTT button when others are talking. When more than one radio transmits on the same channel, the air-wave is jammed and all transmissions are lost.
Listening/Receiving
- The radio speaker receives a signal automatically if the radio is set to the same channel and code as the transmitting radio.
- Ensure the speaker volume is set to an appropriate level.
Adjusting Speaker Volume
- Press from the home screen.
Using Headsets
- When a headset is connected to the radio, the radio speaker is disabled. You need to wear a headset to monitor and receive messages.
- If your headset has a PTT button, you can use the button to make a transmission with the microphone on the headset.
- You can still use the PTT button on the radio to make a transmission with the microphone on the radio.
