The walkie talkie interphone H280 offers a wide range of features and extremely high level of sound clarity.
Feature:
1. long distance communication
With large power range, the communication distance can be as long as 6 km in open spaces.
2. The voice is loud and clear.
The design of creative sound transmission structure, to enable the sound loud and clear.
3. Stable outside case
The outside case is made with thicker material, in order to be safe to be dropped of 1.5m high from the ground.
4. The longer working time
Li-battery of 2050mAh capacity to enable the long working time of 18 hours.
5. High-low power shift
The power of each channel can be set by the high/low power key-board, when the communication range is narrower, it is available to choose the low power to save the battery capacity.
6. 25KHz/12.5KHz the channel interval can be adjusted.
The user can adjust the channel interval between 25KHKz and 12.5KHz by means of software setting, and no need to buy a new one.
7. DTMF ANI (automatic caller ID identify code)
8. 2-Tone decode
Each channel can set this function, when the walkie-talkie receives the signal, the sound and light indication will remind the users.
9. Monitor function
Press MONI key to monitor the current channel status, this function is superior when the receiving signal is weak.
10. Auto power saving function
When theres no signal or no operation, the machine will enter into the power saving mode automatically, to lower down the power consumption and to prolong the battery lifetime.
11. Indication when battery low
Indication when battery low to remind the user of recharge.
12. Lock of busy channel
To avoid the user to receive the signal that is not authorized or to send signal to busy channels, to keep the channel clear and away from disturb.
13. Time-out limitation
To avoid any walkie-talkie to occupy each channel for long.
14. Wireness copy.
To copy the function specification from one walkie-talkie to another by copy wire.
15. Computer programming
User can read and write the frrequency by this function, and set without opening the walkie-talkie.
16. Delete of ending voice
This function will avoid the ending noise while talking off and hanging off.
17. 9 levels adjustment of silent-noise sound.
18. Priority channel scan.
19. Voice indication.
20. Alarming function.
