Uniden UM725 Radio Owner’s Manual
OPERATING THE RADIO
In order to customize your radio to your specic needs, it is important to understand it's
basic operation. Your radio has three main operation modes:
Normal Scan Weather
Monitors a single channel
and lets you talk on that
channel to another radio.
Sequentially checks
for transmissions on all
channels or channels saved
in memory.
Monitors the selected NOAA
weather channel. Hear
the current or forecasted
weather.
MONITORING A CHANNEL (NORMAL MODE)
To monitor a channel, press either of the
CH buttons to select the desired channel
(press and hold to scroll quickly). The
radio will remain on that channel and you
will be able to hear any transmissions on
that channel.
To save the current channel into memory,
press the
MEM
soft key; MEM appears on
screen for saved channels. (To remove
a saved channel from memory, press the
MEM
soft key again.)

Tip: Saving specic channels to memory enables your radio to scan those channels, expanding
your ability to listen for transmissions in your area. If you discover that a saved channel
has a dierent common name in your local area, you can change the channel name using
the Radio Setup menu.
Seng the Squelch Level
The UM725 recognizes signals as transmissions if they
exceed a signal strength threshold that can be adjusted
using the squelch. The squelch feature reduces static
on the speaker by ltering out any background channel
noise.
Increasing squelch requires a signal to be stronger to be
seen as a transmission, ltering out noise and letting only
actual radio transmissions through. Set too high,
you risk missing transmissions lower than the
threshold.
Reducing the squelch allows weaker signals to be
accepted, but can result in "white noise."
While in Standby mode, press the PUSH/VOL/SQ
and turn to adjust the squelch.
