• Check your TX and RX frequencies of your base station to make sure they are not being stepped
on by other frequencies or tuned in a high noise floor environment. If the frequency is clean,
but there is a higher than normal noise floor, you can attenuate the RX sensitivity at the base
station to help lower the noise floor. The pack will TX out more effectively to the base station.
You can do this individually or globally.
• Check your 50ohm Low Loss RF cables for a short in the connector (shield touching the core) or
possibly a broken pin in the connector. Cables get damaged if not taken care of.
Can I power up a base station without hooking up the
antennas?
It is not recommended unless you power up in TX Off mode.
Details:
It is not a good idea to power up the base station without antennas connected because the TX
amplifier is looking for a load when it is powered up. An amplifier with no load will cause strain on the
amp and shorten its life or cause it to fail.
An alternative is to power up the Base Station in TX off mode. Hold the TALK button on the right while
turning on the Base Station. Let go of the TALK button until you see “TX OFF” in the LCD screen.
Another benefit of doing this is that your base station won’t interfere with any other frequencies at
your location if your base station is not already programmed. You can turn the TX in the base station
back on manually or by using the software to program it.
Will my batteries drain if I leave them in the battery charger turned off over night?
No, your batteries will not drain if left in an unpowered battery charger. Always top off a battery
before an event if left unused in or out of the battery charger for longer than a day.
Why don’t I hear the side tone in my packs from my Slave Linked base stations when I key up?
Make sure all your base station RX inputs are connected to an antenna via a VF-8 or DB-VIC RX multi-
coupler.
Can I wear a 2-way radio right next to my RAD Pack?
RAD recommends the user to wear a two-way radio on the OPPOSITE side of the RAD pack to avoid
interference between each other. The 2-way Radio transmission can potentially damage the receiver
board in the RAD pack if it is a few inches in proximity.
