OPERATION

To Use The Desk Charger
CAUTION
To reduce risk of injury, charge only nickel-cadmium
batteries. Other types of batteries may burst causing
personal injury or damage.
1. Turn the radio OFF and place the radio into the charging
sleeve with the speaker facing the front of the charger, or
properly insert the battery into the charger as indicated on
the battery pack making sure the ON-OFF switch on the
battery pack is in the OFF position. (M-RK, Monogram
or Prism HP battery packs do not have an ON/OFF
switch).
2. STANDARD DESK CHARGERe: The CHARGE (red)
indicator will light indicating the battery is being charged.
To charge the battery to maximum capacity, let the battery
pack charge for at least 14 hours.
3. RAPID DESK CHARGER: The CHARGE (red) indica-
tor will light indicating the battery is being charged. (If
the RED indicator is blinking slowly the charger is in the
pre-charging mode. This model results if the battery tem-
8
perature is either too "hot" or "cold", dead or defective, or
if the battery is excessively discharged. If the battery is
excessively discharged, the charger should switch to nor-
mal charge within 10 minutes.)
When the READY (green) indicator lights charging is
complete and the charger is in trickle charge mode.
On occasion when charging a new battery or a battery
which has been out of use for a few months, the charger
will prematurely switch to the trickle charge before the
battery has been fully charged. If this happens, allow
the battery to continue trickle charging overnight. Then
remove and reinsert the battery and observe that the
battery goes through a normal rapid charge before
putting it into service.
To Remove A Battery Pack
Simply reach into the cutouts provided in the sides of
the charging insert and lift the battery pack out.
