FCC Statement

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates and can radiate radio frequency energy. If not installed and used in accordance with the instructions, it may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. Verification of harmful interference by this equipment to radio or television reception can be determined by turning it off and then on. The user is encouraged to try to correct the interference by one or more of the following measures:

  • Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver.
  • Connect the equipment into an outlet on a different circuit to that of the receiver’s outlet.
  • Consult your dealer or an experienced radio/TV technician for help. Operation is subject to the following two conditions:
  • This device may not cause harmful interference.
  • This device must accept any interference received, including interference that may cause undesired operation.

Note: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

Compliance with RF Exposure Standards

The radio complies with the following RF energy exposure standards and guidelines:

  • United States Federal Communications Commission, Code of Federal Regulations; 47 CFR § 1.1307, 1.1310 and 2.1093
  • American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE) C95. 1:2005; Canada RSS102 Issue 5 March 2015
  • Institute of Electrical and Electronic Engineers (IEEE) C95.1:2005 Edition

RF Exposure Compliance and Control Guidelines and Operating Instructions

To control your exposure and ensure compliance with the occupational/controlled environmental exposure limits, always adhere to the following procedures

Guidelines:

  • Do not remove the RF Exposure Label from the device.
  • User awareness instructions should accompany device when transferred to other users.
  • Do not use this device if the operational requirements described herein are not met.

Operating Instructions:

  • Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), press the Push-to-Talk (PTT) key. To receive calls, release the PTT key. Transmitting 50% of the time, or less, is important because the radio generates measurable RF energy only when transmitting (in terms of measuring for standards compliance).
  • Keep the radio unit at least 2.5 cm away from the face. Keeping the radio at the proper distance is important as RF exposure decreases with distance from the antenna. The antenna should be kept away from the face and eyes.
  • When worn on the body, always place the radio in an approved holder, holster, case, or body harness or by use of the correct clip for this product. Use of non-approved accessories may result in exposure levels which exceed the FCC’s occupational/controlled environmental RF exposure limits.
  • Use of non-approved antennas, batteries, and accessories causes the radio to exceed the FCC RF exposure guidelines.
  • Contact your local dealer for the product’s optional accessories

Basic Operations

Turning On or Off the Radio

To turn on or off the radio, press and hold the On-Off key.

Adjusting the Volume

Press the Volume Up key to increase the volume, or Volume Down key to decrease the volume.

Selecting a Zone

A zone is a group of channels within the same operational area. The radio supports 2 zones, each of which consists of up to 16 channels.
To select a zone, press the preprogrammed Zone Up or Zone Down key.

Selecting a Channel

The radio receives and transmits voice and data on the selected channel. Before selecting a channel, make sure that the current zone contains the channel.
Rotate the Channel Selector knob to select a channel

Call on Analog Channel (Without Signaling)

When you are speaking during a call, keep the microphone about 2.5 cm to 5 cm away from your mouth. This ensures optimal voice quality on the receiving radio.
On an analog channel without signaling, you can initiate a call to all the other users on the channel.
Rotate the Channel Selector knob to select the analog channel, and then press and hold the PTT key.

Supplementary Features

VOX

When the voice detected by the microphone reaches the value to trigger the transmission, the radio automatically transmits the voice without the PTT key pressed. The VOX Gain feature preprogrammed by your dealer is used to control the sensitivity of microphone transmission.
Press the preprogrammed VOX key to enable this feature.

Power Level

The Power Level feature allows you to set the TX power level to high or low. High power enables communication with radios far away from you but consumes more battery power. Low power enables communication with radios close to you and saves battery power.
Press the preprogrammed Adjust Power Level key to adjust the power level.

Scan

The Scan feature allows you to listen to activities on other channels, keeping track of your team members.
Press the preprogrammed Scan key to enable this feature.
With this feature enabled, the radio scans according to the scan list preset for the current channel. The LED indicator flashes orange slowly. When detecting activities on a channel, the radio stays on the channel and the LED indicator glows green.

Talk Around

The Talk Around feature allows you to continue communication in direct mode when the repeater malfunctions or your radio is out of the coverage of the repeater.
With this feature preprogrammed by your dealer, press the preprogrammed Talk Around key to switch between direct mode and repeater mode.

Squelch Level

The squelch level refers to the squelch threshold required for the speaker of the radio to be turned on. The higher squelch level requires stronger signal. Press the preprogrammed Adjust Squelch Level key to adjust the squelch level.

Scrambler

The Scrambler feature allows the radio to invert the frequency spectrum of transmitted audio signals. Only the receiving radio with the same Scrambler settings can restore the audio signals. This prevents eavesdropping and ensures communication privacy.
Press the preprogrammed Scrambler key to enable this feature

Monitor

The Monitor feature allows the radio to receive more signals including weak signals, and helps you to recognize weak voices in the speaker.
Press the preprogrammed Monitor key to switch between monitor squelch mode and receive squelch mode.

Squelch Off

With the Squelch Off feature enabled, the speaker will keep unmuted regardless of whether carrier exists. Then the radio sounds background noise.
Press the preprogrammed Squelch Off key to enable this feature.
