Frequently Asked Questions - UHF400R Oricom
What is the maximum range of the Oricom UHF400R?
The maximum range is up to 5 km in open, unobstructed areas. Actual range depends on terrain and weather conditions.
How do I charge the radio?
Insert the radio into the included desktop charger with the battery installed. Connect the charger via the included USB-C cable to a USB power adapter (5V/1A recommended). A full charge takes approximately 3-4 hours.
Can I use non-rechargeable batteries?
No, the UHF400R is designed to work only with the included rechargeable Lithium-Ion battery pack. Using other batteries may damage the radio.
How do I set privacy codes (CTCSS/DCS)?
Press the Menu button, navigate to the CTCSS/DCS setting, and select a code from the list. Both radios must use the same channel and code to communicate privately.
Is the radio waterproof?
The radio has an IP54 rating, meaning it is protected against limited dust ingress and water splashes. It should not be submerged or exposed to heavy rain.
How do I activate VOX (hands-free)?
Press Menu until VOX appears, then select a sensitivity level (0 to turn off, 1-3 for low to high). The radio will transmit automatically when you speak.
What does the Roger beep do?
The Roger beep emits a short tone when you release the PTT button to signal that you have finished speaking. It can be turned on/off via the menu.
Can I charge the radio while it is turned on?
Yes, the radio can be charged while turned on, but charging time may be slightly longer. For fastest charging, turn the radio off.
Why is the transmission range short?
Range is affected by obstacles such as buildings, hills, and heavy foliage. Also, using low power mode (0.5W) reduces range. Switch to high power (2W) for maximum range.
How do I perform a factory reset?
Turn off the radio, then press and hold the Menu button while turning it on. The radio will reset to default settings. All programmed channels and codes will be erased.
