One of the most popular portable radios in the VECTOR VT-44 line. This model was released in early 2007, after the Master model and shortly before the Military model. This station has only two fundamental differences from the basic Master model: the presence of a display and the use of a lithium-ion battery.
A small display with light green backlight, located on the upper end of the device, greatly simplifies the use of the radio station. So, channel programming and some other settings can be done without using a computer.
The use of a lithium-ion battery with a noticeably larger capacity (1500 mA * h) made it possible to reduce the dimensions of the radio and increase the time battery life, but made it problematic to use the station in the cold.
Less fundamental differences Vector 44 H come down to some functional features of this particular model: the control has been slightly changed and the number of channels has been increased to 77.
The transmitter of this radio station has an adjustable power, the maximum value of which is 5 watts. A flexible antenna with a length increased to 160 mm allows you to establish a stable connection at a distance of up to 14-15 km (under ideal conditions).
Design VECTOR VT-44 H - aluminum chassis in a shock-resistant splash-proof polycarbonate case. This is a standard solution for the entire VT-44 series.

Preparation for operation
Battery charge
Before using the VECTOR VT-44 H radio, you need to charge the battery
It may be necessary to perform 2-3 charge-discharge cycles to restore the normal capacity of the battery after a long period of storage.
Warning:
- Avoid charging a fully charged battery. This may lead to a shortened service life.
- After the battery is fully charged, disconnect it from the charger. Leaving the battery in the charger for more than 2-3 days may shorten the life of the battery due to overcharging.
- The ambient temperature should be between 5° and 40° C. Charging the battery in others.
Note:
- Turn off the Vector VT-44 H radio when charging the battery. Turning on the radio may affect the correct battery charge.
- Battery life is limited even if used correctly. Therefore, over time, the battery will need to be replaced.
Turn on the AC adapter to the 220V network and connect it to the charger | |
Insert the battery or radio with battery into the "glass" of the charger
|
|
The battery charge time is 4-5 hours. |
Installing and removing the battery
Average battery life is 8-16 hours (depending on battery capacity) The VECTOR VT-44 H is assumed to operate in 5% transmit, 5% receive and 90% standby mode.
Warning:
- Do not short the battery terminals as this may shorten the life of the battery or destroy it.
- Never try to disassemble the battery.
Antenna Installation
Screw the antenna firmly onto the Vector VT-44 H by turning it clockwise.
Note: The antenna is not a handle, holder or other attachment. Using it for this purpose may damage the antenna and impair the performance of the radio.
Installing a belt clip
Do not use glue or screws to secure the clip, as this may destroy the battery case or the radio.
Installing a cover on the headset jack
If you are not using an optional headset, install a cap on this jack and secure it with a screw.
Note:For stability against external influences, this plug must be installed.
Installing an optional headset
Insert an external headset into the jack.
Note: When using an external headset, the environmental resistance deteriorates.
3. Controls
4. Operation of the radio station
Turn on the VECTOR VT-44H radio by turning the volume control clockwise. A beep will sound.
Adjust the volume level with the volume control to the desired level by turning off the squelch.
Select the desired channel with the channel selector. If you hold the button for more than 2 seconds, the channel scan mode is activated.
To call, press and hold the PTT button, speak in a normal voice at a distance of about 5 cm. Release the PTT button to receive.
Note: if the battery is low, the transmission stops and the indicator flashes red, the battery needs to be charged immediately.
5. Additional features
Keyboard lock
This feature is designed to prevent channel switching if the buttons are accidentally pressed. To enable this function, you must simultaneously press and hold the channel switch buttons for 3 seconds, after a short beep, the key symbol will appear on the display - the keyboard is locked. To unlock, press and hold the switch buttons again.
Channel scan mode
This function is intended for quick retuning or searching for a busy channel. To rebuild up, press and hold for 3 seconds. button to increase the channel number, to tune down - the decrease button. when a busy channel is detected, scanning stops within 5 seconds. To exit the mode, press any of these buttons or the PTT button.
Voice activation mode - VOX
This feature is designed for hands-free operation. To enable this function, turn on the power of the Vector VT-44 H radio station, while holding down the PTT button, after the second beep, release it. To exit the mode, press the PTT button. VOX sensitivity can be changed by setting the display channel from 1 to 16 (in this case, the sensitivity scale) and writing it to memory by turning on the power while holding the PTT and mute buttons, then press PTT to confirm the sensitivity level selection.
Tone mode
This feature is for ring tone transmission. To enable this feature, press the squelch off button, then the PTT button. After turning on the tone signal, press the channel reorder button down - the signal will be broadcast on the air. To turn it off, press the PTT button.
Low Battery Warning
This function serves to warn that the battery is low. During transmission, if the battery is low, the radio stops transmitting, the indicator flashes red, and a beep sounds. The battery needs to be charged or replaced.
Monitor (noise suppressor)
If there is no signal on the selected channel, the squelch automatically turns the radio off and you cannot hear background noise. To manually turn off the squelch, press and hold the squelch off button. When the button is pressed, you hear the noise of the air, and the indicator lights up green.
CTCSS/DCS mode
Some channels can be programmed with CTCSS tones (DCS). This feature will allow you to receive only those signals meant for you (have the same CTCSS/DCS tone) and ignore other radios and interference. These modes are optional and can be activated from a personal computer using a special program.

FAQ on Vector VT-44 Pro
I suggest adding here everything that is not found in the instructions
1. How to switch from LPD to PMR or change the frequency grid without a computer?
To switch from the first grid, for example, to the second one (and there frequencies starting from 409, .... MHz, you must hold the P0 (monitor) and PTT buttons at the same time and turn on the station. Without releasing them, wait for four beeps and the LED flashes, release, and then turn the channel switch to position 2 (2nd frequency grid).Then press the P0 button and hold it until the beep - this is the exit from the grid switching mode.In the same way, you can quickly switch from LPD to PMR band, for example, by doing the above, only set the channel switch to the seventh position.
Unfortunately software allows you to change only the frequencies of the first grid, but the good thing is that these frequencies are duplicated in the third grid.

2. When you try to switch to another channel, the radio beeps
If you press the P1 button, the one on the left, the station will be blocked and when you try to switch to another channel, it will beep. As a rule, for some reason they forget about it, they try to change the station, it is sewn and read, but it still beeps and works only on one channel. Nalo just remember in time and unlock the station by pressing the P1 button again.
Don't step on this rake...
3. How to switch the power of the walkie-talkie without a computer
By default, the power is regulated by the P4 button located on the right. Pressing this button (and one tone and beep) will put the radio into low power mode, pressing it again (and double beep and light) will return it to "high" output power. The real power will be about 4 -4.5 watts. Forcing the output power by software will not lead to any significant
increasing the communication range, but negatively affecting the reliability of the output stage, the manufacturer of course provided a small margin of safety especially for those who like to turn on the radio without an antenna or use the antenna as a handle for carrying or picking their nose. You can control the output with a simple field indicator. A fluorescent lamp is also suitable, but it is not very informative.
