Users must be fully aware of the hazards of the exposure and able to exercise control over their RF 
exposure to qualify for the higher exposure limits.   
RF Radiation Profile 
Radio Frequency (RF) is a frequency of electromagnetic radiation in the range at which radio signals are 
transmitted. RF technology is widely used in communication, medicine, food processing and other fields. 
It may generate radiation during use.   
RF Radiation Safety 
In order to ensure user health, experts from relevant industries including science, engineering, medicine 
and health work with international organizations to develop standards for safe exposure to RF radiation. 
These standards consist of:   
  United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 2 
sub-part J;   
  American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE) 
C95. 1-1992;   
  Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999;   
  International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998; 
FCC Regulations 
Federal Communication Commission (FCC) requires that all radio communication products should meet 
the requirements set forth in the above standards before they can be marketed in the U.S, and the 
manufacturer shall post a RF label on the product to inform users of operational instructions, so as to 
enhance their occupational health against exposure to RF energy.   
Operational Instructions and Training Guidelines   
To ensure optimal performance and compliance with the occupational/controlled environment RF energy 
exposure limits in the above standards and guidelines, users should transmit not more than 50% of the 
time and always adhere to the following procedures:   
  RF energy will be generated only when the radio is transmitting.   
  The radio must be at least 2.5 centimeters away from human body when transmitting. 
  Warning! : This DIGITAL PORTABLE RADIO generates RF electromagnetic energy during transmit 
mode. This radio is designed for and classified as “Occupational Use Only,” meaning it must be used

8.14 TDMA Direct Mode  
Description 
TDMA (Time Division Multiple Access) Direct Mode allows the radio to divide the 12.5 kHz channel into 
two alternative slots in direct mode. If the radio operates on a channel with this feature enabled and one 
time slot is already occupied, it can transmit and receive in the other free time slot.   
Operation   
Enable or disable this feature via CPS by your dealer. With this feature enabled, you can manually 
switch to a digital channel in TDMA Direct Mode or enter the TDMA Direct Mode by powering on the 
radio on a digital channel in TDMA Direct Mode. Under TDMA Direct Mode, the radio will display the icon 
.   
8.15 VOX 
Description 
VOX allows you to trigger the voice transmission by speaking directly without holding down the PTT key. 
When the voice detected by the microphone (either external or internal microphone) reaches the volume 
to trigger the transmission, it will be transmitted automatically.   
Caution 
Follow the instructions below when using the VOX feature:   
 To use the VOX feature with an external microphone, make sure the PTT/VOX switch is switched 
to “VOX” before the radio is powered on and the VOX feature is enabled.   

23 
 The VOX feature will be enabled for all the channels.   
 The VOX feature settings will not remain unchanged when the radio is powered on and off.   
 After the VOX feature is enabled, switching the PTT/VOX switch to “PTT” will disable the feature. 
In such case, switching the PTT/VOX switch to “VOX” will keep the radio transmitting. To make 
the radio function properly, reattach the earpiece to enable the feature again.   
Operation   
Activating or deactivating the VOX feature 
 Go to “Menu -> Settings -> Radio Set -> VOX” to enable or disable this feature.   
  Press the programmed VOX key.   
Adjusting the VOX Gain Level 
Go to “Menu -> Settings -> Radio Set -> VOX -> Gain Level” to adjust the transmission sensitivity.   
Higher gain level can bring lower sensitivity and thus larger voice volume.   
Note 
Please adjust the VOX Gain Level properly to avoid unexpected VOX triggering due to high 
sensitivity or triggering failure due to low sensitivity.   
8.16 CDC/CTC Selected  
Description 
CDC/CTC Selected allows you to select and configure the appropriate CDC/CTC manually.   
Operation   
Press the programmed CDC/CTC Selected key on an analog channel to enter the CDC/CTC editing 
mode. Use the Up and Down key to select the appropriate CDC/CTC. If a reversed CDC is needed, 
press the Cancel/Return Key (the last English character of the CDC will be changed from N to I, 
indicating the CDC is reversed). Finally, press the OK/Menu key to save the configuration. 
To restore the CDC/CTC programmed by CPS and exit the CDC/CTC editing mode, press the Call End 
Key in the CDC/CTC editing mode.

Set your TX/RX frequency and signaling to the 
same as that of other members.   
The  channel  type  (digital  and 
analog)  may  be  set 
inconsistently. 
Make  sure  all  members  are  on  the  same 
digital/analog channel.   
You may be too far away from

Irrelevant 
communication  or 
noise  is  heard  on 
the channel.   
You  may  be  interrupted  by 
radios  using  the  same 
frequency.   
Change the frequency, or adjust the squelch 
level.   
The  radio  may  be  set  without
