you begin listening, adjust the volume to a comfortable level.
Do not listen at extremely high volume levels. Extended high-volume
can lead to permanent hearing loss.
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 cause
discomfort might still damage your hearing.
Traffic Safety
Do not wear an earphone while operating a motor vehicle or riding a
bicycle. This can create a traffic hazard and is illegal in some areas.
Even though some earphones are designed to let you hear some outside sounds
when listening at normal volume levels, they still present a traffic
hazard.
CONNECTING AN EXTERNAL SPEAKER
In a noisy area, a properly placed external speaker (such as Cat. No.
21-549) or an amplified speaker (such as Cat. No. 21-541) might make
listening easier. Plug the speaker cable's 1/8-inch mini-plug into the
scanner's headphone jack.
USING THE BELT CLIP
You can use the belt clip for hands-free carrying when you are on the go.
Slide the belt clip over your belt or waistband.
