INFORMATION
1. SAVE THIS MANUAL - It contains important safety and operating
instructions for MONOGRAM Series Dual Desk Charger.
2. Beforeusingthebatterycharger,readallinstructionsandcautionary
markings on (1) the battery charger, (2) the battery, and (3) the
product using the battery.
3. CAUTION-Toreducetheriskofinjury,chargeonlyEricsson battery
packs.Charging any other battery pack or batteries may cause the
battery to burst and cause personal injury or damage.
4. Do not expose charger to rain or snow.
5. Do not use auxiliary equipment not recommended or sold by the
manufacturer. To do so may result in a risk of fire, electric shock, or
injury to persons.
6 To reduce risk of damage to electric plug and cord, pull by the plug
rather than the cord when disconnecting the charger.

IMPORTANT SAFETY INFORMATION
13. GROUNDING AND AC POWER CORD CONNECTION -To reduce
the risk of electrical shock use only a properly grounded outlet.The
charger is equipped with an electric cord having an equipment-
grounding conductor and a grounding plug. Be sure that the outlet
is properly installed and grounded in accordance with all local codes
and ordinances.
14. DANGER -NeveraltertheACcordorplug.Ifitwillnotfitintheoutlet,
have a proper outlet installed by a qualified electrician. Improper
connection can result in risk of an electric shock.

adapter should be usedonly until a properly grounded outlet canbe
installed by a qualified electrician.
16. DANGER - Before using an adapter as illustrated, be certain the
center screw of the outlet plate is grounded. The green-color 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

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 Charge Slot: For fast charging of a Monogram Series radio with
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. FAST LED:Flashes when radio or battery is inserted into Rear Charge
Slot.
4. SLOW LED:(in Front Charge Slot) illuminates when radio or battery 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 Charge Slot: Insert battery or radio with battery into the Rear Charge
Slot, observing correct polarity. The FAST LED will begin to flash and fast
charge begins according to the amount of charge in the battery.(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 illuminated. After the initial
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
bemaintainedatfullcharge,providedtheradiois turnedoff.TheSLOWLED
is turned on continuously, and may turn 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.
Front Charge Slot:Insert battery or radio with battery into Front Charge Slot,
observingcorrectpolarity.TheSLOWLEDwillbeilluminated,andacharging
current of approximately 50mA is provided to the battery.In the slow charge
mode, the BKB 191 204/1 or BKB 191 204/2 battery will take approximately
14 hours to fully charge.
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.
