  Consult the dealer or an experienced radio/TV technician for help. 
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: 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 
Hytera's  portable 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 environment 
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), 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 generates measurable RF energy 
exposure  only when transmitting (in terms of measuring  for standards compliance). 
  Hold the radio in a vertical position in front of face with the microphone (and the other parts 
of the radio, including the antenna) at least one inch (2.5 cm) away from the nose. Keeping 
the radio at the proper distance is important because RF exposures decrease with distance 
from the antenna. Antenna should be kept away from eyes. 
  When worn on the body, always place the radio in a Hytera's approved clip, holder, holster, 
case, or body harness for this product. Using approved body-worn accessories is important 
because the use of Hytera's or other manufacturer's non-approved accessories may result 
in exposure levels, which exceed the FCC's occupational/controlled environment RF 
exposure limits. 
  If you are not using a body-worn accessory and are not using the radio in the intended use 
position in front of the face, then ensure the antenna and the radio are kept at least 2.5 cm 
(one inch) from the body when transmitting. Keeping the radio at the proper distance is 
important because RF exposures decrease with increasing distance from the antenna. 
  Use only manufacturer's name approved supplied or replacement antennas, batteries, and 
accessories. Use of non-manufacturer-name approved antennas, batteries, and 
accessories may exceed the FCC RF exposure guidelines. 
  Contact your local dealer for the optional accessories of the product. 
The device has been tested and compliance with SAR limits, users can obtain Canadian information on 
RF exposure and compliance

8. Troubleshooting 
Phenomena   Analysis   Solution  
The radio cannot 
be powered on.   
The battery may be improperly 
installed.  
Remove the battery and then reattach it.   
The battery power may run out.  Recharge or replace the battery.   
The battery may suffer from 
poor contact caused by dirtied 
or damaged battery contacts.   
Clean the battery contacts.   
During receiving, 
the voice is weak, 
discontinuous or 
totally inactive.   
The battery voltage may be 
low.  
Recharge or replace the battery.   
The volume level may be low. 
Increase the volume by rotating the Volume 
Control knob.   
The antenna may get loose or 
may be improperly installed.   
Turn off the radio and reattach the antenna.   
The speaker may be blocked 
or damaged.   
Clean the surface of the speaker.   
You cannot 
communicate with 
other members.   
The frequency or signaling may 
be inconsistent with that of 
other members.   
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 or analog channel.   
You may be too far away from 
the group members.   
Move towards other members.   
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 with no 
signaling.

You may locate in an 
unfavorable position. For 
example, your communication 
may be blocked by high 
buildings or frustrated in the 
underground areas.   
Move to an open and flat area, and restart the 
radio to try again.   
You may suffer from external 
disturbance (such as 
electromagnetic interference). 
Stay away from equipment that may cause 
interference.
