Transmission Management
You can initiate a private call, group call or all call (your radio
must be programmed to allow you to use the all call service)
through the same operations on digital channel. When calling
back, the radio will make a call to the calling party in private call
and all call (your radio must be programmed to allow you to call
back in an all call); but in group call, the radio will make a call to
all parties involved when calling back.
Here we take the private call as example to illustrate the call
process:
1. User A and B select the same digital channel.
2. User A holds down the PTT key to initiate a call.
You preset a regular private call/group call/all call contact
for each digital channel via your dealer.
3. User A can talk to the microphone when the LED indicator on
the radio glows red.
4. User A releases the PTT key to finish talking.
User A can hold down the PTT key to talk when the LED
indicator on the radio is glowing orange.
When receiving, the LED indicator on the radio glows green.
5. User B can receive the call without any operation. When
receiving, the LED indicator glows green.
6. User B can hold down the PTT key to talk when the LED
indicator on the radio is glowing orange.
Note: The duration of LED indicator glowing orange (Call Hold
Time) is preset by your dealer. If neither one talks before this
duration expires, the call will end.
Calling on Digital Channel
Calling on Analog Channel (No Signaling)
On the analog channel without signaling, the calling operations
are the same as on the digital channel. The difference is that
the called parties are all the users on the channel, rather
than the preset contact for the channel.
Please refer to the corresponding Feature Book for calling
operations on the analog channel with signaling.

Ibefore using the Digital portable radio, review the following important RF energy awareness and control information and operational
instructions. Comply with this information and instructions in order to ensure compliance with RF exposure guidelines.e the capability to
access information in that form.
This Digital poartable radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more
users over a distance. It uses RF energy or radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other
forms include, but are not limited to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other
forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high levels of x-rays, for example, can
damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations to develop standards for exposure to RF energy.
These standards provide recommended levels of RF exposure for both workers and the general public. These recommended RF exposure
levels include substantial margins of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend specific operating instructions
to users of digital portable radios. These instructions are important because they inform users about RF energy exposure and provide simple
procedures on how to control it. Refer to the following websites for more information on what RF energy exposure is and how to control
exposure to assure compliance with established RF exposure limits:

RF Energy Exposure Awareness And Control
Information For Fcc Occupational Use Requirements
This radio is intended for use in occupational/controlled conditions, where users have full knowledge of their exposure
and can exercise control over their exposure to remain below RF exposure limits. This radio is NOT authorized for
general population, consumer, or any other use.

RF Energy Exposure Information
To ensure bodily exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use. Always adhere to the
following basic guidelines:
• The push-to-talk button should only be depressed when intending to send a voice message.
• The radio should only be used for necessary work-related communications.
• The radio should only be used by authorized and trained personnel. It should never be operated by children.
• Do not attempt any unauthorized modification to the radio. Changes or modifications to the radio may cause harmful interference and/or
cause it to exceed FCC RF exposure limits. Only qualified personnel should service the radio.
• Always use only authorized accessories (antennas, control heads, speakers/mics, etc.). Use of unauthorized accessories can cause the
FCC RF exposure compliance requirements to be exceeded.
The information listed above provides the user with information needed to make him or her aware of a RF
exposure, and what to do to assure that this radio operates within the FCC exposure limits of this radio.
Occupational Safety Guidelines And Safety Training Information
Federal Communications Commission Regulations
Before it was marketed in the United States, the Digital portable radio was tested to ensure compliance with FCC RF energy exposure
limits for two-way portable radios. When digital portable radios are used as a consequence of employment, the FCC requires users to be fully
aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a
label directing users to specific user awareness information. The radio has an RF exposure product label.
Also, the Product Safety Manual and this Operator’s Manual include information and operating instructions required to control RF exposure
and to satisfy compliance requirements.
