Preparations

Mobile Radio Installation

1. Install mobile radio as following figure
   
   

1. Connect to the power and ensure the correctness. Connect the power cable to the lead accumulator (not take off the fuse wire from the power cable.
   
2. Connect the DC power cable to the power connector of mobile radio
3. Replace Fuse Wire: If the fuse wire is fusing, confirm the reason and problems, then replace fuse wire.
   
4. Antenna Connection: As the figure shown: connect the antenna connector and the mobile radio (Note: ensure the connection between mobile radio and antenna is completed before transmitting).
   
5. Microphone Connection
   Before voice communication, plug the microphone connector into the mobile radio base jack of front panel and press tightly. As shown in the figure:
   
6. PC Programming Cable Connection
   Connect the programming cable in the package to the PC through DATA socket and install the specific programming software to read and write the mobile radio.
7. Use the CL-900 clone or transfer cable to connect two mobile radios (through DATA socket).

Basic Operations

Power On/Off

1. Press (power key) to turn on the mobile radio.
   The mobile radio makes loud dual beeps. The screen displays power message for a moment, then displays frequency and other indicators. To turn off the mobile radio, press (power key) for about 1s. When turning off the mobile radio, the mobile radio makes low-volume dual sound, saves the current frequency and specifications, and calls out specifications next power on.

Main Frequency and Sub-frequency Switch

Main frequency refers to the current operating and working channel. Sub-frequency refers to the receiving and monitor channel.

3 methods to switch main frequency and sub-frequency

1. When menu 14(ECHO) is set to "AUTO", the secondary frequency of the monitored signal automatically switches to the main frequency.
2. When menu 14(ECHO) is set as "MANU", when the secondary frequency monitors the signal, it has the same functions as the main frequency within about 3 seconds, such as: it can carry out transmission scanning priority, etc.
3. Long press the MHZ/SET key to switch main frequency and sub-frequency.
   For example, screen public area originally displays TX-L and displays TX-R after switching.

Volume Adjustment

Clockwise rotate the volume knob to increase the output volume and anticlockwise rotate the volume knob to decrease the output volume.

Squelch Adjustment
Clockwise rotate the squelch knob until the background noise (on the screen) disappears to improve weak signals sensitivity.

Transmitting
When transmitting, press the PTT key and away about 5cm from the microphone to normally speak. If main frequency at the left of screen, it will display TX-L, at the right display TX-R. After speaking, release the PTT key.

Output Power Selection

1. Press FUN, MHZ/SET key in turn, then rotate the coding knob to choose menu number 6 (TXP).
2. Press MHZ/SET key and rotate the coding knob to choose H ( high power; default) or M, L3, L2 and L1.
3. Press MHZ/SET key to save settings, or press any other key to cancel.
4. Press any other key to exit the menu mode, except MHZ/SET key.
5. Continuously press LOW/REV key to switch power.

Note:

• Don't transmit with high power for a long time, or it may cause that the mobile radio is over-heated and doesn't normally work.
  Continuously transmit may cause that the radiator is over-heated. In this occasion, don't touch the radiator. When the mobile radio is over-heated due to the high-temperature environment or continuous transmission, for protection circuit, the mobile radio may automatically switch high output power to low output power.
• Power switch can be proceeded in the power switch allowance channel. Frequency Selection

VFO Mode

VFO mode is a basic mode to change operating frequency. To enter VFO mode, press VFO key. Clockwise the coding knob to increase frequency and anticlockwise the coding knob to decrease frequency. Microphone UP/DWN key can be used to adjust frequency.

• Press microphone UP/ DWN key to continuously up-regulate or down-regulate frequency. UP/ DWN
• MHz Mode

If the needed operating frequency is far away from the current frequency, use MHz tuning mode to adjust quickly.

1. When in VFO mode or call mode, press [MHZ/SET]·MHz digital blinking
2. Turn the encoding knob to select the desired MHz value
3. press any key to set the selected frequency and return to VFO mode
4. Use the coding knob or microphone (UP][DWN] key to continue adjusting the frequency as needed

Directly Input Frequency

1. Press VFO/B key. Directly input frequency must be in VFO mode.
2. Press the microphone PF/D key with Enter function, that is the microphone Enter key.
3. Press the number key 0 to 9 to input the needed frequency.

If only changes MHz numbers and keeps KHz numbers same, press the VFO/B key instead of the microphone Enter key. The input assigned frequency will be confirmed when the microphone Enter key is pressed.

Menu Settings

Menu Visit

1. Press FUN, MHZ/SET key in turn to enter menu interface.
   
2. Rotate the coding knob to choose the needed menu. When changing menu numbers, the screen will display short introduction of each menu and current specifications.

Scan

Normal Scan

When operating the mobile radio in VFO mode, the mobile radio has two scan modes: band scan and programming scan.

Band Scan

Note:

• Programming scan channel (L0/U0~L1/U1) and the call channels be locked.
• Call scan can be proceeded between the call channel and the memory channel, even the memory channel is locked.

Scan Restoration Method

The mobile radio will stop scanning when detecting the frequency or the memory channel signal. The mobile radio will continue or stop to scan according to restoration methods you choose.

• Time Operating Mode (Default)
  The mobile radio stays for about 5s on the busy frequency ( or memory channel). The mobile radio will continue to scan, even the signal still exists.

Fault Elimination

Problems	Reasons	Measures
Connect 13.8V DC power and press (power) key, the mobile radio can't be turned on and screen doesn't display.	Power cable is connected backwards. One or more fuses of power cable cut down.	Connect randomly supplied power cable correct: Red (+) and Black (-). Check the reason of blown fuse and recorrect. Install new fuse wire with the same rating.
Screen is still dark even the higher brightness is chosen.	Supply voltage is low.	Supply voltage needs to be 13.8V DC ±15% (11.7 V to 15.8 V DC). If input voltage is out of the range, adjust stable power supply and check all power cables connection.
Frequency can't be chosen through rotating coding control knob or pressing microphone UP/DWN key.	Memory call out mode is chosen.	Press VFO key.
Most keys and coding control knob don't work.	Lock function is activated. The mobile radio is in channel display mode.	Unlock all lock functions. When the mobile radio is turned off, press (power) key + REV key to exit channel display mode.
Memory channel can't be chosen through rotating coding knob or pressing microphone UP/DWN key.	Memory channel doesn't save data.	Save data in some memory channels.
Mobile radio can't transmit even pressing PTT key.	Microphone plug doesn't fully plug into the connector of front panel. Selected transmitting frequency difference makes transmitting frequency is out of allowance range	Turn off the mobile radio and plug microphone plug until it is fixed. Press FUN and MHZ/SET key, then rotate the coding control knob to choose menu number 5 (SFT). Press MHZ/SET key and rotate the coding knob to choose OFF.
