DANGER

- Never alter the AC cord or plug. If it will not fit in the outlet,
have a proper outlet installed by a qualified electrician. Improper
connection can result in risk of an el ect ric shoc k.

15. The BML 161 54/1,3 charger 120 V ac lin e cord has a g rounding plug
that looks like the plug illustrated in Figure l. A temporary adapter,
which looks lik e the ad apter i llustra ted in sk etches B and C, m a y be
used to connect this plug to a two-pole receptacle as shown in sketch
B if a properly grounded outlet is not available. The temporary
adapter should be u sed only unt il a prop erly ground ed outl et can be
installed b y a qu al if ie d el ect rician .

DANGER

- Before using an adapter as illustrated, be cer tain the
center s crew of the out let plate is grou nded. The green- color rigi d
ear or lug extending from the adapter must be connected to a
properly grounded outlet--make certain it is grounded. If necessary,
replace the outlet cover plate screw with a longer screw that will
secure adapter ear or lug to outlet plate and make ground connection
to grounded outlet.

17. Care should be taken when placing the charger in service to insure
proper top and bottom ventilation. A minimum of 1/4" is required
between the bottom of the charger and the surface on which it sits.

INDICATORS

1. Rear C ha r ge S lot: For fast char g in g o f a Mo no gra m Series radi o w it h
battery or independent charging of batteries. Polarity of battery in
charger must be correct, or no charging will occur.

2. Front Charge Slot: For slow charging of Monogram Series radio with
battery or independent charging of batteries. Polarity of battery in
charger must be correct, or no charging will occur.

3. F AST LED: Flashes when radio or battery is inserted into Rear Charge
Slot.

4. SLO W LED: (in F ront Cha rge Slot) i llumin ates when radi o or ba ttery is
inserted. SLOW LED: (in Rear Charge Slot) will illuminate when fast
charge is complete, or fully charged battery is inserted.

5. Power LED: Indicates AC power is supplied to charger.

NEVER INSERT A RADIO INTO THE CHARGER WITHOUT A BATTERY
INSTALLED

CHARGER OPERATION

Rear Ch arge S lot: Inser t ba ttery or radio wit h batt er y into the Re ar Ch arge
Slot, obser ving corr ect polar ity. The FAST LED will begin to flash and fast
charge begi ns accor din g to the amou nt of cha rge in the batte ry. ( ln the case
of a fully discharged battery, the initial charge is executed during the first
minute. The FAST and SLOW LED’s will not be i lluminat ed. After the init ial
charge, the battery mode will change to fast charge.)

ln the fast charge mode, the BKB 191 204/1 or BKB 191 204/2 battery will
take approximately 1 hour to fully charge.

If the initial charge on the battery is over 95%, then the fast charge mode will
turn to a "trickle-charge" mode. ln the "trickle-charge" mode, the battery will
be maintai ned at full charge , provided the r adio is turned off . The SLOW LED
is turned on continuously, and may tur n off momentarily every 34 seconds
by the "trickle-charging" current. If the battery is charged to 100% of its
capacity, the FAST LED will turn off and the SLOW LED wiIl turn on.

F ront Char ge Slot: Inse rt battery or rad io with ba ttery into F ront Cha rge Slot,
observing correct po larity . The SLOW LED will be i lluminated, and a charging
current of app ro x imatel y 50mA i s pro vid ed to the b attery. In the slo w cha rge
mode, th e BKB 191 2 04/1 or BKB 1 91 20 4/2 bat tery will tak e a pproximatel y
14 hours to fully charge.

NO T E

On occasion when charging a new batter y or a battery which has
been out of use for a few months, the charger will prematurely switch
to the tric kle cha rge before the batt ery has been fully ch arged . If this
happens, allow the battery to continue trickle-charging overnight.
Then remove and reinser t the battery and observe that the battery
goes throug h a no rmal ra pi d cha rge before puttin g it int o service .
