Status Indicators

The radio indicates its operational status in the following ways:
◆ LED indicators
◆ Prompt tones

LED indicators
The LED indicators show the operational status of the radio.

• Red on: The radio is transmitting signals, and sending encrypting calls or data.
• Green on: The radio is powering on, receiving signals or and encrypting calls or data.
• Flashing jade Green: The radio is scanning.

Prompt Tones
The prompt tones provide voice prompts of the device status or data reception responses. You can enable or disable the related prompt tones on the programming software.

• Call Start of Digital: A Beep can be heard when the PTT key is pressed.
• Voice End of Digital: A Beep can be heard when the voice is end.
• Call End of Digital: A Beep can be heard when the PTT key is released.
• Call Start of Analog: A Beep can be heard when the PTT key is pressed.
• Voice End of Analog: A Beep can be heard when the voice is end.
• Low-battery alarm tone: Repeated tones can be heard when  the battery voltage is low. You can set the duration on theprogramming software.

Advanced Functions

The radio provides the following advanced functions:
◆ DMO dual-time slot
◆ Scanning list
◆ Scanning
◆ VOX
◆ Talkaround
◆ Remote Monitor
◆ Remote Kill and Activate

DMO Dual-Time slot
In a DMO dual-time slot communication, two calls can be made onthe same frequency, making the communication efficiency double and saving the cost for users for frequency request and use. In addition, dual-time slot communication can be ensure smooth  and real time communication even in the peak time.

Scanning List
You can create a scanning list and allocate it to a single channel ora call group. Your radio can check whether there are voice activities on the current channel or in the current call group by cyclically scanning the channels and call groups in the list. Your radio can  support up to 10 scanning list and each list consists of up to 16 members.

Scanning
When you enable scanning, your radio check whether there are voice activities on the current channel by cyclically scanning the prep-rogrammed scanning list.
The LED indicator flashes jade green. Automatic scanning: the radio starts to scan automatically after you select an active channel or call group with automatic-scanning enabled

Starting and Stopping Scanning
Procedure:

1. Start or stop scanning by pressing the pre-programmed scanning key or selecting a channel with a pre-programmed scanning list with the channel selection knob.
2. When scanning is started, the LED indicator flashes jade green. When scanning is stopped, the LED indicator is off.

Transmitting a Response During Scanning
During scanning, your radio stays on the active channel or in the active call group detected. The duration when the radio stays on the channel is called the pre-programmed time limit of the “Hold time”.
Procedure:

1. During the hold time, press the PTT key and talk to the microphone after the LED indicator is red on.
2. Release the PTT key to receive the call.If you do not send a response, the radio starts to scan other channels or call groups.

Setting a Power Level
You can set the power level of each channel to low or high.

A high power level is used for the communication between the radio and a remote portable radio. A low power level is used for the communication between the radio and a near portable radio.
Procedure:

1. Press the pre-programmed power level key.
2. If the radio beeps once, it indicates that high power is transmitted.lf the radio beeps twice, it indicates that low power is transmitted.

Enabling or Disabling the VOX Voice Control Function
VOX allows you to initiate a hand-free voice call without pressing PTT key. Once the microphone detects a voice signal, including VOX earphone or other voice accessories, the radio will automaticly transmit the signals in the time period.
Procedure:

1. Press the programmed VOX key to enable or disable the VOX function
2. Talk to the microphone clearly.

Talkaround
lf the forwarder does not work or if your radio is beyond the operating scope of the forwarder but within the coverage of other portable radios, you can still use your radio for communication.
This is called “Talkaround” Procedure:
Press the programmed Repeater/Talkaround key to switch over between the Talkaround and Repeater mode.

Remote Monitor
This function enables remote listening of the radio.
Procedure:

1. You should program the side key as One Touch Call feature, and setup the Contacts who you want to monitor via. software and Choose Feature type as “Remote Monitor”
2. Press the programmed One Touch Call key to monitor the pre-set channel.

Remote Kill and Activate
This function enables remote kill and activate of radio.
Procedure:

1. You should program the side key as One Touch Call feature, and setup the Contacts who you want to Kill or Activate via. software and set up the Feature type as “Radio Kill / Activate”
2. Press the programmed One Touch Call key to Kill or Activate the pre-setchannel.
