the risk of ele ctri cal shoc k us e onl y a p rop erly g rou nded ou tlet . The
charger is equipped with an electric cord having an equipmentgrounding cond uct or an d a grou ndin g plug . Be sure that the out let
is properly installed and grounded in accordance with all local codes
and ordin a n ces.
14.
DANGER
- Never alter the A C cord or plug. If it will not fit in the outlet,
have a proper outlet installed by a qualified electrician. Improper
connection can resu lt i n risk of an el ect ric sho c k.
15. The MGCH3K char ge r 1 20 Vac line cord ha s a g ro un ding plug that
looks lik e the pl ug il lustrat ed in Fig ure l . A tempor ary adapter, which
looks like the adapter illustrated in sketches B and C, may be used
to con nec t th is pl ug t o a two -po le r e cep ta c le as sh own i n sket c h B
if a pr operly g rounde d outl et is n ot a vai lable . The tempor ary adapte r
should be u sed only until a properly gr ounded outlet can be install ed
by a qualified electrician.
16.
DANGER
- Before using an adapter as illustrated, be cer tain the
center s crew of the outlet pl ate is grounded . The green-colo r rigid
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 Cha r ge Sl ot : For fast c h argin g o f a Mo no gram Se ries radio 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 Front Charge Slot) il lumin ates when radio 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

CHARGER OPERATION
Rear Charg e Slot : Inser t battery or radio with ba ttery into th e Rear Ch arge
Slot, observ ing correc t polarit y. The FA ST LED wi ll begin to flas h and fast
charge be gins a ccord ing t o the amou nt of charge in t he b atte ry. ( ln the case
of a fully discharged battery, the initial charge is executed during the first
minute. Th e FAST and S LOW LED’s will not be illumin ated. After the initia l
charge, the battery mode will change to fast charge.)
ln the fast charge mode, the BKB 191 204/1 or BKB 191 204/2 batter y 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 char ge, provid ed the radio is t urned 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 Cha rge Slot: Insert battery or rad io with ba ttery into F ron t Charge Slot,
observing correct polarity . The SL OW LED will be illuminated, and a cha rging
current of a ppr o xim atel y 50 mA is pr o vided to th e bat tery. In the slo w cha rge
mode, th e BKB 191 2 04/1 or BKB 191 204/ 2 bat tery will t ak e a pproximately
14 hours to fully charge.
NO T E
On occasion when charging a new battery or a batter y which has
been out of use for a few months, the charger will prematurely switch
to the tric kl e char ge before the batt ery has been ful ly charg ed. If this
happens, allow the battery to continue trickle-charging overnight.
Then remove and reinser t the battery and observe that the battery
goes thro ug h a no rmal r a pi d cha r ge before puttin g it int o service .
