Analog and Digital Interphone(150M/400M)
一、Overview
The interphone has two working modes:
1. Transceiver Same Frequency Mode: multiple interphones set the same working frequency for receiving and transmitting, and ground communication dispatching can be carried out after simple networking. The communication distance is about 4km radius.
2. Transceiver Different Frequency Mode : with the help of relay station, the communication distance is about 8 km radius, with better communication quality and longer communication distance.
Walkie talkie appearance, as shown below.

二、Characteristic
1. Working mode: analog or digital trunking.
2. The structure is firm and durable, wear-resistant and anti-aging.
3. TR-P130 walkie talkie supports conventional mode (DMR).
4. TCB-C-236E interphone supports normal mode (DMR/PDT/NXDN) and cluster working mode.
5. TCB-C-236E walkie talkie supports normal mode (DM/RM) and digital and analog services in direct mode (DM). It supports trunking mode (TM) and PDT/DMR digital trunking communication system services, and realizes trunking communication functions such as selective call, group call and individual call. It supports digital and analog services in trunk mode (RM).
6. Support Beidou/GPS positioning function.
7. The 2.4-inch/2.0-inch translucent LCD color display screen is adopted, so that the display information can be seen clearly even in outdoor strong light. The ergonomic appearance design greatly enhances the accuracy and comfort of operation.
8. Support IP68 level dustproof and waterproof.
