Mobile Operation
The vehicle battery must have a nominal rating of 12V. Never connect the transceiver to a 24V battery. Be sure to use a 12V vehicle battery that has sufficient current capacity. If the current to the transceiver is insufficient, the display may darken during transmission, or transmitting output power may drop excessively.
Route the DC power cable supplied with the transceiver directly
1.
to the vehicle's battery terminals using the shortest path from the transceiver.
We recommend you do not use the cigarette lighter socket as some
cigarette lighter sockets introduce an unacceptable voltage drop.
The entire length of the cable must be dressed so it is isolated from
8
heat, moisture, and the engine secondary (high voltage) ignition system/ cables.
After installing cable, in order to avoid the risk of damp, please
2.

Important
reading is desired.
Antenna Connection
Before operating, install an efcient, well-tuned antenna. The success of
your installation will depend largely on the type of antenna and its correct installation. The transceiver can give excellent results if the antenna system and its installation are given careful attention.
Use a 50Ω impedance antenna and low-loss coaxial feed-line that has a characteristic impedance of 50Ω, to match the transceiver input
impedance. Coupling the antenna to the transceiver via feed-lines having
an impedance other than 50Ω reduces the efficiency of the antenna
system and can cause interference to nearby broadcast television receivers, radio receivers, and other electronic equipment.
Transmitting without first connecting an antenna or other matched load may damage the transceiver. Always connect the antenna to the transceiver before transmitting.
All xed stations should be equipped with a lightning arrester to reduce the risk of re, electric shock, and transceiver damage.
The possible locations of antenna on a car are shown as following:
Initial Installation
Optional Accessory Connections
External Speaker (not included)
If you plan to use an external speaker, choose a speaker with an
impedance of 8Ω. The external speaker jack accepts a 3.5mm (1/8")
mono (2-conductor) plug.
External speaker adopt double port BTL, please care about the connecting way. The speaker can not connect with the ground, otherwise the speaker
will be fault. The wrong connecting way as the following picture.

Mute Out
Capable of muting the car stereo when you receive incoming traffic on
the tranceiver. This transceiver has a mute out function allowing you to hardwire directly to a compatable head unit with existing mute functionality.
Microphone
For voice communications, connect a microphone equipped with an 8-pin modular plug into the modular socket on the front of the main
unit. Press rmly on the plug until the locking tab clicks. Attach the
supplied microphone hanger in an appropriate location using the screws included in the screw set.

Australian Broardcasting Requirements
Transmit and Receive Procedure
Your two-way radio contains a transmitter and a receiver. To control your exposure and ensure compliance with the general population/ uncontrolled environment exposure limits, always adhere to the
following procedure: • Transmit no more than 50% of the time.
• To receive calls, release the PTT button.
• To transmit (talk), press the Push to Talk (PTT) button.
Transmitting 50% of the time, or less, is important because the radio generates measurable RF energy exposure only when transmitting (in terms of measuring standards compliance).
Radio Operation and EME Exposure
Unauthorised antennas, modications, or attachments could damage
the radio and violate compliance. Do NOT hold the antenna when the radio is “IN USE.” Holding the antenna reduces the effective range.
36
Do not use the radio if the antenna is damaged. If a damaged antenna makes contact with your skin, a minor burn can result.
Electromagnetic Iterference/Compatability
Nearly every electronic device is susceptible to electromagnetic interference (EMI). To avoid the possibility of electromagnetic interference and/or compatibility conflicts, turn off your radio in any location where posted notices instruct you to do so such as health care facilities.
Aircraft
When instructed to do so, turn off your radio when onboard an aircraft. Any use of a radio must be in accordance with applicable regulations per airline crew instructions.
Medical Devices
Pacemakers
The Advanced Medical Technology Association recommends that a minimum separation of 6 inches (15cm) be maintained between a radio and a pacemaker. These recommendations are consistent with the independent research by and recommendations of the U.S. Food and Drug Administration.
People with pacemakers should:
• ALWAYS keep the radio more than 15cm from their pacemaker when
the radio is turned ON.
• Not carry the radio in the breast pocket (Handheld Radio).
• Use the ear opposite the pacemaker to minimise the potential for
interference.
• Turn the radio OFF immediately if there is any reason to suspect that
interference is taking place.
Hearing Aids
Some radios may interfere with some hearing aids. In the event of such interference, you may want to consult your hearing aid manufacturer to discuss alternatives.
Other Medical Devices
If you use any other personal medical device, consult the manufacturer of your device to determine if it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this information.
General Warnings
Keep the radio out of reach of babies and young children.
Transmitting Range
The talk range will depend on your surroundings and environment it will be affected by obstructions such as hills or buildings.
Talk range depends on the terrain. It will be affected by concrete structures, heavy foliage and by operating radios indoors or in vehicles.
Your DB477C is simplex “one way at a time”. While you are speaking, you can not receive a transmission.
Your DB477C is on an open-license band. Always identify yourself when transmitting on the same channel.
IMPORTANT: Before transmitting on a UHF channel listen to ensure it is not already in use.
Australian Broardcasting Requirements
15
Transmitting (sending speech)
The unit is continuously in the Receive mode when the unit is turned ON and not transmitting. When a signal is received on the current channel, “RX” icon will be displayed on the LCD screen. a. Press and hold the PTT (Push to Talk) button to transmit your voice. The transmit signal icon “TX” will display on the LCD screen. b. Hold the unit in a vertical position with the Mic (Microphone) 5 cm away from the mouth. While holding the PTT button, speak into the microphone in a normal tone of voice. c. Release the PTT button when you have finished transmitting.
For others to receive your transmission, they must be on the same channel as you.
Call Ring Tone
You can use the CALL button to send a tone to other users on the same channel. To activate this feature; a. With the unit in normal mode, press and release the CALL button. The unit will transmit a 2-second page tone to the other unit/s set with the same channel within transmitting range. NOTE: This function is only possible every 60 seconds.
Roger Beep
37
This is a tone which is automatically transmitted whenever the PTT button is released. This alerts the receiving party that you have ended the transmission, and you are now in receive mode.
38
Australian Broardcasting Requirements
Channel 5 and 35 (paired for Duplex repeaters) are reserved as emergency channels and should be used only in an emergency. CTCSS and DCS will not operate on channels 5 and 35.
A list of currently authorised channels can be obtained from the ACMA website in Australia and the MED website in New Zealand. Channel 11 is a calling channel generally used to call others and channel 40 is the customary road vehicle channel. Once contact is established on the calling channel, both stations should move to another unused “SIMPLEX” channel to allow others to use the calling channel. Channels 22 and 23 are for Telemetry and Telecommand use, voice communications are not allowed on these channels by law. Channel 9 and above are the best choices for general use in Simplex mode.
Radiocommunications (Citizen Band Radio Stations) Class Licence 2002
No licence is required to own or operate this radio in Australia and New Zealand. The Radiocommunications (Citizen Band Radio Stations) Class Licence 2002 contains the technical parameters, operating requirements, conditions of licence and relevant standards for Citizen Band (CB) radios. CB radios must comply with the class licence for their use to be authorised under the class licence.
UHF channels and frequencies
IMPORTANT NOTE: The operation of your UHF radio in Australia and
New Zealand is subject to conditions in the following licenses: In Australia
the ACMA Radio communications (Citizen Band Radio Stations) and in New Zealand by MED the General User Radio License for Citizen Band Radio.
You may encounter operational issues changing over from 25kHz to
12.5 kHz channel spacing. Operating volumes can vary when receiving wideband (5kHz deviation) transmissions on newer narrow band equipment or narrow band (2.5kHz deviation) transmissions being sent
to older wideband equipment. Older and newer adjacent channels can
cause interference.
