Recharging Ni-Cd or Ni-MH Batteries

Average charge time varies, depending on
capacity. Typically, Ni-MH batteries charge
in about 10 hours. Ni-Cd batteries charge in
approximately four hours.

You can use your radio while charging the
batteries if you employ a DC to DC
regulated and filtered adapter (such as
RadioShack catalog number 273-1859), but
not if you employ an AC to DC regulated
adapter (such as 273-1762).

Controls

If you hold down PTT over 2 minutes, the
radio automatically stops transmitting to
save power. The radio will generate an alert
tone and

JN

JN

will flash on the display if you

continue to hold down PTT.

The radio automatically scans through quiet
codes while scanning through the channels.
The quiet code feature automatically turns
on when a signal is detected on a channel
and quiet code, and turns off after the signal
disappears. To stay on the active channel
and quiet code, press PTT to stop scanning
before the signal disappears.

Using Key Lock

When the keys are locked, you can still send a
page to other FRS radios set to the same
channel by holding down

¹ý

/CALL, but you

cannot select a channel by pressing

¹ý

/CALL.

The EPA certified RBRC®
Battery Recycling Seal on the
nickel-cadmium (Ni-Cd) battery
indicates RadioShack is
voluntarily participating in an
industry program to collect and recycle these
batteries at the end of their useful life, when
taken out of service in the United States or
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 bans/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.
