Canada. The RBRC program provides a convenient alternative to placing used Ni-Cd batteries
into the trash or the municipal waste stream, which may be illegal in your area. Please call
1-800-THE-SHACK (1-800-843-7422) for information on Ni-Cd battery recycling and disposal
band/restrictions in your area. RadioShack's involvement in this program is part of the
company's commitment to preserving our environment and conserving our natural resources.
External Power
You can power your scanner using a 9V, 500mA AC/DC adaptor and size C adaptaplug™
(neither supplied).
To use an external power source:
1. Always connect the adaptor (nor supplied) to the scanner first.
2. Plug the adaptor into the power source.
3. To disconnect, unplug the adaptor from the power source first.
If you use an external power source for regular operation, install alkaline batteries for
emergencies. Rechargeable batteries will self-discharge, even when not used, and could have no
usable power.
Caution: You must use a Class 2 power source that supplies 9V DC and delivers at least 500mA.
Its center tip must be set to positive and its plug must fit the scanner's PWR DC 9V jack. Using
an adaptor that does not meet these specifications could damage the scanner or the adaptor.
Headphones and Speakers
You can plug headphones or an amplified speaker (neither included) into your scanner's
headphone jack. This automatically mutes the scanner's speaker.
Even though some earphones/headphones let you hear some outside sounds when listening at
normal volume levels, they still can present a traffic hazard.
Listening Safely
To protect your hearing, follow these guidelines when you use an earphone or headphones.
Set the volume to the lowest setting before you begin listening. After you begin listening, adjust
the volume to a comfortable level.
Do not listen at extremely high volume levels. Extended high-volume listening 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.
