Operating Instructions
Power On/Off and Volume Control
- Power/Volume Knob: Rotate the top knob clockwise to power on the radio and increase the volume. Rotate counter-clockwise to decrease volume and power off.
Channel Selection
The PX-999S features 38 GMRS channels. Rotate the channel knob on top of the radio to select your desired channel. A voice prompt will announce the channel number.

Figure 3: Connecting to a Repeater for Extended Range.
- Channels 1-14: These are shared with FRS and are typically low power channels.
- Channels 15-22: These are high power channels, offering better range.
- Channels 23-38: These channels are designated for repeater use, allowing for significantly longer communication distances when connected to a GMRS repeater.
Push-to-Talk (PTT) Operation
- To transmit, press and hold the PTT button located on the side of the radio. Speak clearly into the microphone.
- Release the PTT button to listen for incoming transmissions.
VOX Function (Voice Operated Transmission)
The built-in VOX function allows for hands-free communication. When activated, the radio will automatically transmit when it detects your voice.

Privacy Codes (CTCSS/DCS)
The PX-999S supports 260 privacy codes (sub-codes) to help prevent interference and ensure more private conversations. While the manual does not detail programming these codes directly on the radio, they are pre-configured on channels to secure call content and prevent crosstalk.

NOAA Weather Radio/Scan
Stay informed about weather conditions with the integrated NOAA Weather Radio/Scan feature. This function automatically scans 10 weather (WX) band channels and receives weather reports from designated NOAA stations.

Squelch Levels
The PX-999S offers 10 squelch levels to filter out weak background noise and improve sound clarity. Adjusting the squelch level helps ensure clear communication by suppressing static when no signal is present.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Battery depleted or not properly installed. | Charge the battery fully. Ensure the battery is securely attached. |
| Cannot transmit or receive | Incorrect channel selected. Out of range. Battery low. | Ensure both radios are on the same channel. Move closer to the other radio. Charge the battery. |
| Poor sound quality/static | Weak signal. High squelch level. Interference. | Move to an open area. Adjust squelch level. Check for sources of interference. |
| Limited range | Obstacles (buildings, terrain). Using low power channels. | Move to an open area. Switch to high power channels (15-22). Consider using a GMRS repeater for extended range. |
| NOAA Weather Radio not working | Not in range of a NOAA station. | Ensure you are within range of a designated NOAA weather station. |
