Preparation for use
Battery charge
Before using the VECTOR VT-44 H radio, you must charge the battery
It may be necessary to perform 2-3 charge-discharge cycles to restore the battery to normal capacity after long-term storage.
Warning:
- Avoid charging a fully charged battery. This may result in a shorter service life.
- Once the battery is fully charged, disconnect it from the charger. Leaving the battery on the charger for more than 2-3 days may shorten the battery life 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. The radio being turned on may affect whether the battery is charged correctly.
- The battery life is limited even if used correctly. Therefore, the battery will need to be replaced over time.
 |
Turn on the power adapter to a 220V network and connect it to the charger |
 |
Insert the battery or radio with battery into the “cup” of the charger
|
| The battery charging time is 4-5 hours. |
Installing and removing the battery
The average battery life is 8-16 hours (depending on battery capacity). It is assumed that the VECTOR VT-44 H radio operates in 5% transmit, 5% receive and 90% standby mode.
Warning:
- Do not short-circuit the battery terminals: this may shorten its service life or destroy it.
- Never attempt to disassemble the battery.
Antenna installation
Screw the antenna tightly onto the Vector VT-44 H radio station by rotating it clockwise.
Note: The antenna is not a handle, holder or other attachment. Using it for these purposes may damage the antenna and impair the performance of the radio.
Installing a Belt Clip
Do not use glue or screws to attach the clip; this may destroy the battery or radio housing.
Installing a cover on the headset jack
If you are not using an additional headset, install a cover on this jack and secure it with a screw.
Note:To ensure resistance from external influences, this plug must be installed.
Installing an additional headset
Insert the external headset into the jack.
Note: If you use an external headset, the resistance to external influences will deteriorate.
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, turning off the squelch.
Select the desired channel using the channel selector. If you hold the button for more than 2 seconds, the channel scanning mode is activated.
To make a call, press and hold the PTT button, speak in a normal voice at a distance of about 5 cm. To receive, release the PTT button.
Note: If the battery is low, transmission stops and the indicator flashes red, the battery needs to be charged immediately.
5. Additional features
Keypad lock
This feature is designed to prevent switching channels when buttons are pressed accidentally. 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 designed to quickly change or search for a busy channel. To move up, press and hold for 3 seconds. button to increase the channel number; to change downwards, use 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 function is designed for hands-free operation. To enable this function, turn on the power of the Vector VT-44 H radio station, holding down the PTT button, and after the second beep, release it. To exit the mode, press the PTT button. VOX sensitivity can be changed by setting the display to channel 1 to 16 (in this case, the sensitivity scale) and storing it in memory by turning on the power while holding down the PTT and squelch mute buttons, then pressing PTT to confirm the sensitivity level selection.
Tone mode
This function is designed to transmit a tone signal. To enable this function, you must press the squelch off button, then the PTT button. After turning on the tone signal, press the button for changing channels down - the signal will be transmitted on air. To turn off, press the PTT button.
Low Battery Warning
This function serves to warn you 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 off the radio receiver so you can't hear background noise. To manually turn off the squelch, press and hold the squelch off button. When the button is pressed, you hear the air noise and the indicator light turns green.
CTCSS/DCS mode
Some channels may have CTCSS (DCS) tones programmed into them. This feature will allow you to receive only those signals that are intended for you (have the same CTCSS/DCS tone) and ignore signals from other radio stations and interference. These modes are additional and can be activated from a personal computer using a special program.

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 a light green backlight, located on the top end of the device, significantly simplifies the use of the radio station. Thus, channel programming and some other settings can be made 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 size of the radio and increase battery life, but made using the station in the cold problematic.
Less fundamental differences between the Vector 44 H come down to some functional features of this particular model: the controls have been slightly changed and the number of channels has been increased to 77.
The transmitter of this radio station has adjustable power, the maximum value of which is 5 W. A flexible antenna increased to 160 mm in length allows you to establish stable communications at a distance of up to 14-15 km (in ideal conditions).
The design of VECTOR VT-44 H is an aluminum chassis in a shock-resistant splash-proof polycarbonate case. This is a standard solution for the entire VT-44 series.

Vector VT-44 Pro FAQ
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 (and there are frequencies starting from 409,.... MHz), you need to hold down the P0 (monitor) and PTT buttons at the same time and turn on the station. Without releasing them, wait for four sound signals and the LED blinks, release, and then turn the channel switch to position 2 (2nd frequency grid). Then press the P0 button and hold it until the sound signal - this exits the grid switching mode. In the same way, you can quickly switch, for example, from LPD to PMR range by doing the above, only set the channel switch to the seventh position.
Unfortunately, the software only allows you to change 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 locked and when you try to switch to another channel it will beep. As a rule, for some reason they forget about this, try to change the station, it is sewn and readable, but it still beeps and works only on one channel. It’s easy to 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 a walkie-talkie without a computer
By default, the power is adjusted 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 beeping and beeping) will return it to “high” power output mode. The actual 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 will negatively affect the reliability of the output stage. The manufacturer, of course, has provided a small margin of reliability 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.
