If there's any electromagnetic interference, please keep the mobile radio away from the sources such as TV set, engine generator etc.
Regulations: 47 CFR part 2 sub-part J To control your exposure and ensure compliance with the general population or uncontrolled environment exposure limits, transmit no more than 50% of the time. The radio generates measurable RF energy exposure only when transmitting. The consumer must maintain a minimum safe separation distance of 2 ft from the antenna when transmitting.
Getting to Know The COM-DB90 Please check the packaging of your radio for any signs of damage. Carefully open the box, if you find the radio or the included accessories are damaged or lost, immediately contact your dealer or us at info@utvcom.com Front of the Radio 1. 2. 3. 4. 5. 6. 7. 8. 9.

Antenna Do not transmit without an antenna attached to the mobile radio. This can cause stress and harm to the internal transmitter and damage the mobile radio. Choose an antenna suitable for transmitting on user frequencies with an impedance of 50 ohm. If an antenna is not properly tuned for the frequency you transmit on this could cause reflective damage to the radio. Target an SWR of 1.5:1 and never exceed a SWR of 2.5.
Powering TheCOM It is preferred that TheCOM be connected (the positive lead RED wire) directly to the positive post of the vehicle’s battery. If this is not available a fuse block may be used. If external noises are heard through the radio such as “alternator wine” (could be from pumps, switches, lights, clutch fans, other accessories) it is recommended that the power be re-rout directly to the battery posts. Turning on the Mobile Radio Press and hold the volume knob down until the display lights up.
