200018 User’s Guide Draft
The
PRO18 features a built-in battery charging circuit that will charge Ni-Cad and Ni-MH batteries. The
charger provides a slow rate charge that will fully charge a set of typical Ni-MH AA batteries in
approximately 16 hours. The charger is active when the radio is connected to an external USB power
source and the radio is powered off. When connected to an external USB power source and powered
on, the radio operates using the external power source but does not charge the batteries. Charging is
controlled by a timer. Your PRO-18 provides an indication when the internal battery charge circuit is
active. An animated battery icon indicates that the PRO-18 is connected to external power and the
internal battery charger circuit is active.
Warning: The external DC power input is designed to accept external power from the USB data cable
and from USB power adapters. Turn the PRO-18 off prior to connecting or disconnecting external
power.
Warning: Discontinue use of any battery that exhibits leakage, swelling or abnormal generation of heat.
When you charge rechargeable batteries, do not over charge them. Overcharging shortens battery life
and may cause battery failure.
Connecting an Earphone or Headphones
For private listening, you can plug an 1/8-inch (3.5 mm) mini-plug earphone or headphones (not
supplied) in the HEADPHONE jack on top of the PRO-18. This automatically disconnects the internal
speaker.
Listening Safety
Do not wear headphones, earphones, or earbuds while operating a motor vehicle or riding a bicycle.
This can create a traffic hazard and could be illegal in some areas. To protect your hearing, follow
these guidelines:
. Do not listen at high volume levels. Extended high-volume listening can lead to permanent hearing
loss.
. Set the volume to the lowest setting. Then turn on your scanner and adjust the volume to a
comfortable level.
. Avoid increasing the volume. Your ears will adapt to the volume level, so a level that does not cause
discomfort could still damage your hearing.
Connecting an External Speaker
In a noisy area, an amplified speaker (not included, available at your local RadioShack or
RadioShack.com) might provide more comfortable listening. Plug the speaker cable’s 1/8-inch (3.5
mm) mini-plug into the scanner’s HEADPHONE jack.
Attaching the belt clip
Align the belt clip to the belt clip receptacle on the rear of the radio. Slide the belt clip downward until it
snaps into place. Ensure that the locking clip on the belt clip is fully engaged with the lock tab on the
rear of the radio. To remove the belt clip, squeeze the locking clip on the belt clip to disengage it from
the lock tab on the rear of the radio, and slide the belt clip upward.
