What is the SoundTracker® System on the COBRA HH38 WX ST?
The SoundTracker® System is a patent-pending technology that dramatically improves the transmission and reception of CB signals. It cuts incoming noise and strengthens the outgoing signal.
The system reconfigures the transmission signal to be transferred more efficiently through cluttered airwaves. Simultaneously, it significantly reduces the amount of static on all incoming CB signals. This results in cleaner, clearer-sounding reception and a more powerful transmission.
How do I attach the antenna to my COBRA HH38 WX ST?
1. Insert the antenna into the BNC Antenna Connector on top of the radio.
2. Turn the antenna clockwise a quarter turn (1/4) to lock it in place.
How do I install or replace the batteries in the COBRA HH38 WX ST?
The COBRA HH38 WX ST requires 9 “AA” alkaline or NiCD batteries (not included).
1. To remove the battery chamber cover, press down on the arrow on the back of the unit and slide the cover off.
2. Install the 9 “AA” batteries, ensuring you follow the polarity markings (+/-). Ignoring the polarity markings can cause damage.
3. Replace the cover.
When batteries are low, the BATTERY icon will flash on the LCD display. Replace alkaline batteries or recharge NiCD batteries. NiCD rechargeable batteries should be charged for a minimum of 12 hours with a CA-45C charger.
How do I attach and remove the belt clip on the COBRA HH38 WX ST?
To attach the belt clip:
1. Slide the belt clip up on the rails of the base on the back of the radio until the tab locks.
To remove the belt clip:
1. Lift the tab out and slide the belt clip down.
How do I turn on my COBRA HH38 WX ST?
Rotate the ON-OFF Volume Control knob clockwise. When the radio turns on, a series of tones will be heard, and the icons will briefly appear on the LCD display. The LCD will light up for 5 seconds.
How do I set the squelch on the COBRA HH38 WX ST?
Squelch acts as a “control gate” for incoming signals. When set properly, it filters out background noise while allowing transmissions to be heard.
1. Turn the ON-OFF Volume Control knob clockwise to turn the radio on and set a comfortable listening level.
2. Turn the Squelch control knob fully counterclockwise. This opens the “gate” and you will hear noise (hissing). All signals will enter.
3. To achieve the Desired Squelch Setting (DSS), slowly turn the Squelch control knob clockwise just until the noise stops. This is the DSS setting. Now, only signals stronger than the background noise will be heard.
How do I select a channel on the COBRA HH38 WX ST?
1. Turn the power ON using the ON-OFF Volume Control knob.
2. For a higher channel, push the UP arrow key on the side of the radio.
3. For a lower channel, push the DOWN arrow key on the side of the radio.
For quick channel advance, push and hold the desired arrow key.
Note: When switching from one channel to another, the squelch may need to be reset.

2. Select the first channel you want to monitor (e.g., Channel 11) using the CHANNEL UP/DOWN key.
3. Push and release the FUNC key. The FUNC icon will appear.
4. Push and hold the DW key until you hear a “beep”. The DW icon will flash, and the FUNC icon will disappear.
5. Select the second channel you want to monitor (e.g., Channel 17) using the CHANNEL UP/DOWN key.
6. Push the DW key until you hear a “beep”. The DW icon will stay on solid.
7. The display will now switch between the two selected channels.
