Scanner Setup
Connecting Headphones
For private listening, you can plug a mono earphone or headset into the 
Headphone Jack on the back of your scanner. This automatically disconnects 
the internal speaker. Note that the sound is not in stereo.
Listening Safely
To protect your hearing, follow these 
earphone or headphones guidelines:
• Do not listen at extremely high 
volume levels. Extended high-
volume listening can lead to 
permanent hearing loss.
• Set the volume to the lowest 
setting before listening. Turn 
on the scanner, and adjust the 
volume to a comfortable level.
• After you set the volume, do not 
increase it. Over time, your ears 
adapt to the volume level, so a 
volume level that does not cause 
discomfort might still damage 
your hearing.
Connecting the External Alert Out
To provide additional alerting options for the weather alert, connect a 
switch-closure activated device such as a strobe or siren controller (not 
supplied). The devise can be up to 200mA, AC/DC 20V and must have a
3.5mm mono plug cable. Plug the device into the Alert Out Jack on the back 
of your scnner.
Understanding Your Scanner
We use a few simple terms in this manual to explain the features of the 
scanner. Familiarize yourself with these terms and the scanner’s features, and 
you can put the scanner to work for you right away. 
The scanner scans conventional frequencies. A frequency, expressed in 
MHz, is the tuning location of a station. To find active frequencies, use the 
search function or consult an online resource such as www.radioreference.
