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.
Note: Pressing the PTT button cancels the VOX transmission.
Call Tone
When you send a Call Tone, the receiving radio sounds a tone similar to phone ringing
tone.
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.
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 trans-
mission.
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.
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.
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.)
Battery Capacity Maintenance
The T37 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. Turn off the radio while charging.

Channel and Codes
• Set your radios with the same channel and code setting 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 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 T37 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 instruction 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 to use high power channels for more reliable communications.
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.
Note: Connect the USB charger to a nearby and easily accessible wall power outlet.
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.
