Channels and Sub Codes

• You must set your radios with the same channel and sub code setting to enable communication with other radios.
• The channel setting controls the radio frequency. To avoid jamming, you can select a channel that is not used by others in your area. For more information on selecting unused channel, see Scan in Table 3.
• Match the sub code setting on the transmitting and receiving radios. Otherwise, the receiving radio blocks the received signals. This feature helps you to mute unwanted voices from other radio users transmitting on your channel.
• When sub code is set to zero, radio does not block any signals. Everything that is picked up on the channel is sent to the speaker. Motorola Solutions recommends setting your sub code to zero if you are using T92 H2O radios with radios that do not support the sub code feature. For detailed instructions on ways to change settings, see Navigating the Menu Pages on page 1.You can copy channel and sub code settings from one radio to multiple radios simultaneously with the Easy Pairing feature.

2. Ensure that the speaker volume is set to an appropriate level.

Adjusting Speaker Volume

• Press the + or – button from the home screen.

• If your headset has the 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

Additional Information

iVOX or VOX

The microphone detects if you are talking when using Internal Voice Operated
Transmission (iVOX) or Voice Operated Transmission (VOX). If you are talking, the radio triggers the 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.

To select the VOX/iVOX sensitivity level, select the following settings:

L3| Low Sensitivity for noisy environments. Speak up to trigger the VOX or iVOX transmission

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

Scan

Radio scans for voice activity by cycling through the channels. When signals are detected, the signal is sent to the speaker. Scan feature allows you to find out the channel that is used by other groups and has heavy traffic. Scan feature helps you to avoid busy channels when deciding the 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.

Maintenance

This radio is waterproof to IP-67 standards. The radio can withstand submersion up to 1 meter of water for up to 30 minutes, but only when the battery cover and headset accessory port are sealed.

Open the battery compartment door or headset port cover only when the radio is dry. Installation of batteries and accessories must be in dry environments only. Ensure that the battery compartment and accessory port seals are free of all dirt and debris.

To maintain audio quality, if the radio is submerged in water, shake the radio briskly to remove water trapped inside the speaker grille and microphone port. Motorola Solutions recommends rinsing the radio with fresh water if the radio is exposed to salt water to preserve the life of the radio.

Water Sensor

When the radio comes in contact with water, the white LED begins to flash until the battery is dead. Press the Flashlight button to turn off the flashing LED.

Emergency Alert Mode

You can use the Emergency Alert feature to signal members in your group if you require urgent help. After pressing the Emergency button, a warbling alert tone is emitted from your radio and transmitted to the radios in your group. The T92 H2O radios in your group automatically advance the speaker volume to the maximum setting and sound a warbling alert tone for 8 seconds. After 8 seconds, the alert tone stops. Then, the radio is in hands free mode for 22 seconds, allowing you to talk without pressing the PTT button. For the 30 seconds duration of the Emergency Alert mode, T92 H2O radio controls and buttons are locked to maximize reception of the emergency message.

Warning: Use the Emergency Alert feature in case of emergency only. Motorola Solutions is not responsible if there is no response to the emergency alert from the receiving group.

Battery Information
The rated battery life is measured under the industrial standard 5-5-90 duty cycle under lab conditions. 5% of the time transmitting, 5% receiving with speaker on, and 90% waiting for incoming call. Risk of explosion if the battery is replaced by an incorrect type.

Caution: Use only Motorola Solutions approved batteries.

Battery Capacity Maintenance

• Charge the NiMH batteries once every three months when not in use.
• Do not leave the radio connected to a charger permanently.
• Remove the battery from the radio after using for storage purposes.
• Store the NiMH batteries in a temperature between –20 °C to 35 °C and in low humidity

Push-to-Talk Time-Out Timer
