Press the PTT key to talk. When you finish talking, release the PTT key. (Press the key to transmit, release the key to receive).

Featured Function CTCSS/DCS Code The distribution of the CTCSS/DCS code can decrease the interference between radios, but radios can’t communicate with each other with different CTCSS/DCS codes. To ensure your private communication, each channel has 0-121 CTCSS/DCS codes to be set.

##### TOT

To prevent accidental transmission or occupying channel for a long time, if you press the PTT key to continuously transmit for 60s, the device will make a continuous warning tone and stop transmitting.

##### Key Lock

To prevent accidentally changing the setting of the radio, press the CALL/Key Lock for 3s or until the key lock icon is displayed. At this time, you can turn on/off the radio, adjust the volume, receive, transmit, transmit call

tone and monitor channel. But other functions are locked. To unlock the device, press the CALL/Key Lock for 3s or until the key lock icon is not displayed.

Scan Channel Use scan to monitor the reeving of the channel or find the people who accidentally change the channel in your group. Press the SCAN key for 3s and the scan icon appears, the radio starts to scan. When detecting the channel activities, you can hear the receiving. To answer, press the PTT key in 5s and the channel will be confirmed.

Set and Send Call Tone Your device can send different call tones to other devices in your group to remind the people you want to communicate. Set Call Tone

Send to call tone other devices, the device needs to set the same channel and CTCSS/DCS codes as yours, then press the call tone key to call.

Note: the call tone is set to 0, all call tones are ineffective. VOX Function The VOX function allows the user to start transmitting towards the microphone without pressing the PTT key.

|L3 = High sensitivity|

|---| |L2 = Middle sensitivity| |L1 = Low sensitivity| |L0 = Turn off the VOX function|

##### Set Dual Standby Channel

Check Channel Before Transmitting Your device has 21 channels and they display with the cyclic method. To achieve uninterrupted communication, please don’t communicate on the channel if other people are communicating on that channel. To check channel activities before communication, long press the MON/DOWN key, the channel can be used if you listen to the white noise.

#### Remarks:

Exclusions from Warranty Coverage:

Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and 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 circuit different from that to which the receiver is connected.

—Consult the dealer or an experienced radio/TV technician for help.

FCC/ISEDC RF Exposure Requirements: For body-worn operation, this radio has been tested and meets the FCC/ISEDC RF exposure guidelines when used with accessories supplied or designated for this product. Use of other accessories may not ensure compliance with FCC/ISEDC RF exposure guidelines. Normal Position Hold the transmitter approximately 25 mm from your face and speak in a normal voice, with the antenna pointed up and away.

FCC/ISEDC exigences d'exposition aux RF: Pour une utilisation sur le corps, cette radio a été testée et est conforme aux directives FCC /ISEDC sur l'exposition aux RF lorsqu'elle est utilisée avec les accessoires fournis ou spécifiés avec ce produit. L'utilisation d'autres accessoires peut ne pas garantir la conformité aux directives de la FCC/ISEDC sur l'exposition aux RF. Position normale Tenez l'émetteur à environ 25 mm de votre visage et parlez d'une voix normale, avec l'antenne pointée vers le haut et éloignée.

This device complies with Innovation, Science, and Economic Development Canad licence-exempt RSS standard(s). Operation is subject to the following two conditions:

Le présent appareil est conforme aux CNR d' Innovation, Sciences et Développement économique Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes :

Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push-To-Talk (PTT) button.

To receive calls, release the PTT button. Transmitting 50 % of the time, or less, is important because this radio gener ates measurable RF energy exposure only when transmitting (in terms of measuring for standards compliance).

Facteur de cycle nominal ne dépassant pas 50% du temps de transmission. Pour envoyer (appel), appuyez sur le bouton Push to talk (PTT). Pour répondre à un appel, relâchez le bouton PTT. Il est important d'émettre 50% ou moins du temps, car une telle radio ne produit une exposition mesurable à l'énergie RF (en termes de mesure de la conformité aux normes) que lorsqu'elle émet.
