This document describes the Gowei G1pro/G2pro Two-Way Radio, a wireless communication device designed for various uses, including outdoor activities, public events, and professional settings like warehouses or jobsites. The radio is built with durability in mind, featuring waterproof, dustproof, and drop-proof characteristics.
Function Description:
The Gowei G1pro/G2pro is a two-way radio that facilitates convenient and easy communication over short to medium distances. It operates on 22 channels and offers 99 privacy codes (38 CTCSS and 61 DCS codes) to minimize interference from other users. The radio supports hands-free operation (VOX) and includes features like a call ringtone, keystroke tones, Roger Beep confirmation tone, and Vibra Alert for incoming signals. Users can select between high and low power modes, with high power offering greater communication distance at the cost of battery life, and low power providing better power efficiency over shorter distances. The device also includes scan and monitor modes to find nearby transmitting channels and listen to weak or intermittent signals, respectively.
