CHAPTER 2 Safety Instruction and Installations
Safety Instructions
WARNING: Hot plug is not allowed since it may cause system halted.
To prevent fire or electrical shock, do not expose the device to rain or moisture.
The encoder modulator is powered with a voltage of 12V DC. The power supply voltage must not exceed the
recommended voltage, which otherwise may cause irreparable damage to the device and the invalidation of the warranty.
Therefore:
lDo not replace power supply with a voltage greater than 12V DC.
lDo not connect the device to the power if the power cord is damaged.
lDo not plug the device into mains supply until all cables have been connected correctly.
lDo not cut the cord.
Avoid placing the device next to central heating components and in areas of high humidity.
Do not cover the device with elements that obstruct the ventilation slots.
If the encoder modulator has been kept in cold conditions for a long time, keep it in a warm room minimum 2 hours before
plugging into the mains.
Mount the device in vertical position with the connectors located on the top side.
When replacement parts are required, be sure the service technician has used replacement parts specified by the
manufacturer or have the same characteristics as the original part. Unauthorized substitutes may result in fire, electric
shock or other hazards.
Safety check- Upon completion of any service or repairs to this device, ask the service technician to perform safety checks
to determine that the device is in proper condition.
Installations
RISK of damage to the unit
Mechanically handling the unit may result in damage. Do not connect the unit to the power supply before or during assembly.
Connect the unit as below instructed.
NO HOT PLUG AND CONNECT THE CABLE AS FOLLOWING STEPS.
1. Mount and tighten the screws and plugs to secure the unit to the wall. Left 10 cm of free space around from each unit.

2. Connect the signal input in the respective connectors. The signal source
can be from a surveillance monitor, DVD, set-top box, CCTV and etc.
3. Optionally, connect the loop-through RF input coaxial cable.
4.Connect cable to RF output to STB/TV.
5.Power supply connection: a) Connect the earth cable; b) Connect the power
plug to the unit mains connector; c) Connect the power plug to the mains
socket.
Cascade Installation
FUTV4624 unit has 1 TV signal to RF output encoded as DVB-T Digital TV signal.
Several FUTV4624 units can be cascaded in order to increase the capacity.
The maximum capacity of a series of N units is 1xN incorporated TV signals.
To cascade 2 or more units, connect the RF output of the preceding unit to
the TVinput (loop-through) of the next unit (see right illustration).

CHAPTER 3 Operations and Management
FUTV4624 is controlled and managed through the key board and LCD display.
LCD Display – It presents the selected menu and the parameter settings. The backlight in the display is on when the power
is applied.
LED – These lights indicate the working status
lPower: It lights on when the power supply is connected.
lAlarm: It lights on when the there is error, such as the signal source loss.
lUSB: It lights on when the USB properly connected and detected.
Left/Right/Up/Down buttons – Use these buttons to turn the screen pages, shift the target items by moving the triangle, or
change the parameter settings in the program mode.
Enter – Use this button to enter a submenu or save a new setting after adjustment; press it to start adjusting the value of
certain items with Up/Down buttons when the corresponding underline flash;
Press it to activate the hidden selections and change the setting with Up/Down (or Left/ Right) buttons.
Menu – Press this button to step back
Lock – Locking the screen / cancelling the lock state, and entering the main menu after the initialization of the device. After
pressing lock key, the system will question the users to save present setting or not. If not, the LCD will display the current
configuration state.
When the power is connected, the LCD will start to initialize the program. The LCD menu goes as below chart.
