Listening Safely
To protect your hearing, follow these
guidelines when you use an ear-
phone or headphones.
• Do not listen at extremely high
volume levels. Extended high-
volume listening can lead to per-
manent hearing loss.
• Set the volume to the lowest set-
ting before you begin listening.
After you begin listening, adjust
the volume to a comfortable
level.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a
volume level that does not

UNDERSTANDING THE 
SCANNER’S MEMORY
You can store up to 110 frequencies
into your scanner’s memory. You
store each frequency into either a
memory called a channel, or a tem-
porary memory called a monitor. This
scanner has 100 channel memories
and 10 monitor memories.
Channel-Storage Banks
To make it easier to identify and se-
lect the channels you want to listen
to, channels are divided into 10 chan-
nel-storage banks of 10 channels
each. Use each channel-storage
bank to group frequencies, such as...

FREQUENCIES IN 
CHANNELS
You can manually store up to 100 fre-

cluding Fire and Emergency Servic-
es,” “Official Maritime Frequency
Directory” and “Official Aeronautical
Frequency Directory.”
Radio Shack updates these directo-
ries every year, so be sure to get a
