Dual-Bay FAST Charger for GMRS/FRS
SM
2-Way Radios
OWNER’S MANUAL —
Please read before using this equipment.
Ô NOTES Ô
• Fully discharge Ni-Cd batteries before
charging. Repeated partial dischar ging and
recharging may shorten battery life. This
does not apply to Ni-MH batteries.
• It is normal for batteries to become warm
while charging.
• If the LED changes to RED after several
seconds, the radio may not be inserted
firmly.
• For batteries with a capacity of less than
600mA, the charging time may be less than
50 minutes and the batteries can be warmer
(than batteries with a capacity greater than
600mA) during charging.
• Use only the supplied adapter. Use of other
adapters may damage your charger.
• If dead batteries, non-rechargeable
batteries, or batteries installed in the wrong
direction are detected, the LED changes to
red and stops charging. When charging two
radios, if one of the radios is turned on, both
radios enter the slow charging mode and
may not be fully charged after hours of
charging. For the fastest charge, turn both
radios off.
• Never attempt to charge any batteries other
than Ni-Cd or Ni-MH rechargeable batteries.
• Only charge batteries of the same type and
capacity. Do not mix new and old batteries or
batteries of different types or capacities.
• Charge batteries in a location that is
between 50°F and 86°F (10°C and 30°C). If
the location is too cold, the batteries cannot
be fully charged. If the location is too warm,
the batteries may be damaged permanently
and lose their ability to charge.
