Retevis RB67 - Advanced Features and Safety; CTCSS;DCS Code Reference; Keyboard Sound and Roger Beep; Transmit and Receive Procedures

Transmit and receive
1. Hold the walkie-talkie 2-3 cm away from your mouth.
2. Long press the PTT key during talking, and the LCD screen will display the transmit icon .
3. Release the PTT button to receive, when the walkie-talkie receives a signal matching the channel, the LCD screen will display receive

Battery level display
The battery power display icon (0-3 grids) shows the current remaining battery power. When the battery shows that there is no bar, it
will send out a "crack" prompt every 15 seconds. When the power is lower than 3.1V, it will automatically shut down.
Battery capacity maintenance
1.When not in use, charge the lithium battery once a month.
2.When storing, remove the battery from the walkie-talkie.
3.Store lithium batteries in a place with a temperature between -20°C and 35°C and low humidity, avoiding moisture wet conditions and
corrosive materials.
Scan
1. Long press the key, and the screen will display the icon to start scanning.
2. When the channel detected by the walkie-talkie matches the current channel number and CTCSS/DCS, the walkie-talkie will stop scanning.
Keyboard sound
1.Short press the key, the icon will be displayed on the LCD screen.
2. Short press or to select on/off.
3. Short press the PTT button to confirm and exit the menu.
