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.

Volume Adjustment: Use the up/down buttons to increase or decrease the volume. Avoid holding the radio close to your ear if the volume is set to an uncomfortable level.
Push-to-Talk (PTT): Press and hold the PTT button to transmit, speaking into the microphone from about 2 inches (5 cm) away. Release the PTT button to listen for a response.
Call Button: Press and release the CALL button to send a three-second call tone to the other party, establishing voice communication.
Lock Function: Press and hold the Lock button for 3 seconds to lock or unlock the MENU, up/down, and MON buttons, preventing accidental operation. A beep confirms the lock status, and a lock icon appears on the display when enabled.
Voice Activated Transmit (VOX): Allows hands-free transmission when speaking. The VOX sensitivity level (1-3, with 3 being most sensitive) can be adjusted via the MENU button.
Key Tone: An audible tone sounds each time a button is pressed. This feature can be turned on or off through the MENU.
Roger Beep Confirmation Tone: An audible tone heard by the listener when the PTT button is released, signaling that the speaker has finished talking. This can be enabled or disabled via the MENU.
Vibra Alert: Alerts the user to incoming signals with an audible call tone or an audible tone with vibration. This feature can be turned on or off through the MENU.
High/Low Power Selection: Accessed through the MENU, allowing users to choose between high power (HI) for extended range or low power (LO) for battery efficiency.
Scan Mode: Press the MON button to automatically search for nearby transmitting channels. The radio will pause temporarily when a channel is found. Users can press PTT or MON to stop scanning or use the up/down buttons to continue.
Monitoring Mode: Hold the MON button for 3 seconds to enter monitoring mode, which is useful for listening to weak or intermittent signals.
Holster: The radio comes with a holster that easily attaches to a belt, purse, or backpack for convenient carrying.

Maintenance Features:

Battery Installation: Involves unscrewing the holster and battery door, connecting the battery with proper polarity, placing it in the compartment, aligning wires carefully to avoid interfering with the O-ring seal, screwing down the battery cover mildly, and re-attaching the holster.
Charging:
- Desktop Charger: Insert the radio(s) into the desktop charger, connect the USB Type-C cable to the back of the charger, and plug it into a USB-compatible power port.
- Direct Cable Charging: Insert the Type-C connector directly into the charge jack at the bottom of the radio.
- The radio displays a flashing battery icon while charging, and the indicator light turns red during charging and green when full. Gowei recommends turning off the radio while charging.
Cleaning: Do not use cleaners or solvents. Use only a damp or dry cloth to clean the exterior.
Battery Care: Do not incinerate, discard in fire, disassemble, crush, puncture, shred, or attempt to change the form of the battery. Do not dry a wet battery with heat sources. In case of leakage, wash skin with soap and water, neutralize with mild acid, and seek medical attention if liquid gets into eyes.
Recycling: Local, state, or federal laws may prohibit disposal of batteries in ordinary trash. Consult local waste authorities for recycling/disposal options.
Factory Reset: In the off state, press the MENU button and MON button simultaneously to restore all settings to their factory default.
