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-ground-
ing conductor and a grounding plug. Be sure the outlet is properly in-
stalled and grounded in accordance with all local codes and ordinances.
14. DANGER - Never alter the AC cord or plug. If it will not fit in the out-
let, have a proper outlet installed by a qualified electrician. Improper
connection can result in risk of an electric shock .
15. The Rapid Charger 120 Vac line cord has a grounding plug that looks
like the plug illustrated in Figure 1. A temporary adapter, which looks
like the adapter illustrated in sketches B and C, may 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 used
only until a properly grounded outlet can be 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 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 be-
tween the bottom of the charger and the surface on which it sits.

DESCRIPTION
The Universal Multi-unit Charger is designed to charge Ericsson per-
sonal radio battery packs. The charger is available either as a Standard or
Rapid Charger and is capable of charging up to six battery packs at one time.
The Standard Multi-unit Charger is capable of fully charging battery
packs in 14 hours and Rapid Desk Charger charges most battery packs in
one hour or less. The use of interchangeable battery sleeves permits charging
different battery pack families at the same time (i.e. two M-RK and four M-
PD sleeve inserts in the same charger).
Both the Standard and Rapid Multi-unit Chargers may be powered by
either a 120 Vac (50/60 Hz) or 230 Vac (50/60 Hz) power source. Power
source selection is made by switching the Voltage Selection switch to the
proper source voltage and using the correct power cable (see Accessories
and Replacement parts).
Battery Pack sleeves are available for the following Ericsson personal ra-
dios:
RADIO TYPE SLEEVE NUMBER
M-PA, M-PD, MTL, PLS, & TPX 344A3072P5
PCS 344A3072P6
M-RK 344A3072P7
Recharging any battery pack or batteries other than the ones your
equipment was designed to charge may result in damage to equipment,
leakage, or explosion.
CAUTION

INSTALLATION
The Multi-unit Charger may be located on a desk or other flat surface or
mounted on a vertical wall in a convenient location. Ensure either a 120 or
230 Vac 50/60 Hz power source is located near the charger. Check the
charger’s voltage selection switch and verify it matches the source voltage.
When locating it on a flat surface be sure to allow 1/4" clearance around the
top and bottom covers to provide adequate ventilation.
When mounting the Universal Multi-charger on a wall be sure the wall is
strong enough to support the charger and a full compliment of radios.
Hollow walls - It is not recommended that the charger be mounted di-
rectly to the wall due to the possible weight (26 lbs max) involved. We sug-
gest mounting the charger on an 18" x 18" plywood panel secured to the
wall studs. The following steps describe the process for installing the panel
and mounting the charger.
1. Locate the studs, studs are normally 16" apart, measured center-to-cen-
ter.
2. Position the top of the panel at the desired height and drill pilot holes
through the panel into the studs. Secure the panel to the studs using four
2 1/2" long screws.
3. Using the template, locate keyhole slots for the Multi-charger mounting
screws. Install the four No. 8 x 1 1/2" mounting screws and mounting
spacers (provided). Install charger on mounting spacers by pressing
down on the charger allowing the mounting spacers to seat into the
charger keyhole slots. The weight of the charger will hold it firmly to
the wall.
9

Solid walls - To install the charger on a brick or concrete wall, first insert
four wood dowels or fiber, plastic or masonry mounting anchors. Use the
following procedure:
1. Using the mounting template provided, locate and mark the charger
keyhole mounting points. Drill the holes to match the anchor’s diameter
and depth using a carbide drill. Insert the anchor into the holes.
2. Screw the four No. 8 x 1 1/2" screws and mounting spacers (provided)
into the anchors.
3. Install the charger on the mounting spacers by pressing down on the
charger allowing the mounting spacers to seat into the charger keyhole
slots. The weight of the charger will hold it firmly to the wall.

INDICATORS
CHARGE (RED) CONTINUOUS: Indicates battery is charging at the se-
lected charging rate
STANDARD MULTI-UNIT CHARGER
11

RAPID MULTI-UNIT CHARGER
If both CHARGE and READY indicators are blinking fast, immedi-
ately unplug the charger and return it for service. If left in this con-
dition, the battery may be severely overcharged causing personal
injury or damage.
WARNING
12

STAND-BY Both indicators are OFF. Battery not installed.
CHARGE (RED) CONTINUOUS: Indicates battery is charging at the se-
lected charging rate.
BLINKS SLOWLY: Indicates a BATTERY FAULT
condition which is preventing an acceptable rapid
charge. This condition may result if the battery is too
hot or cold, weak or dead, or defective. If the blinking
CHARGE indicator does not turn to a continuous RED
after 15 minutes, remove and reinsert the battery.
Weak or Dead Battery - The CHARGE indicator goes to
continuous RED after the battery has an acceptable pre-
charge (typically less than 10 minutes).
Cold or Hot Battery - The CHARGE indicator stays in a
blinking RED condition until the battery temperature
reaches acceptable limits and the battery is removed
and reinserted to clear the fault condition.
Defective Battery - The CHARGE indicator stays in a
blinking RED condition after clearing the fault by re-
moving and reinserting the battery .
READY
(GREEN) CONTINUOUS: Indicates charging is complete and charger has switched to trickle charge.
PROBLEM
(RED/GREEN) BLINKING FAST: When both indicators are blinking fast, either the output has a short circuit or an abnormal
output condition exists.
13

OPERATION
Using The Desk Charger
1. Plug in the charger and turn it on using the ON/OFF power switch lo-
cated in the rear.
2. Turn the radio OFF and place it into the proper charging sleeve with
the speaker facing the front of the charger. If only charging a battery
pack, properly insert the battery pack 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 battery packs do not have an ON/OFF
switch).
3. STANDARD MULTI-UNIT CHARGER: The CHARGE (red) indicator
will light indicating the battery is being charged The proper charge cur-
rent for long or short case battery packs is selected by the insert micro
switch. To charge the battery to maximum capacity, let the battery pack
charge for at least 14 hours
4. RAPID MULTI-UNIT CHARGER: The CHARGE (red) indicator will
light indicating the battery is being charged. (If the CHARGE indicator
is blinking slowly - the charger is in the pre-charging mode. The charger
should switch to normal charge within 10 minutes). When the READY
(green) indicator lights - charging is complete and the charger is in
trickle charge mode.
For indoor use only. To reduce risk of injury, charge only nickel cad-
mium type rechargable batteries. Other types of batteries may explode
causing personal injury or damage. Replace defective cords immedi-
ately.
CAUTION
14

To Remove ABattery Pack
Simply reach into the cutouts provided in the sides of the charging insert
and lift the battery pack out.
DEFINITIONS
Dead Battery Battery pack with low voltage due to long term self
discharge or extreme discharge.
Hot Battery Battery Pack excessively warmed by charging or en-
vironmental temperature conditions.
Cold Battery Battery pack excessively cooled by an environmental
condition.
Defective Battery Battery pack with one or more of the internal cells
shorted.
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 hap-
pens, allow the battery to continue trickle charging overnight. Then re-
move and reinsert the battery and observe that the battery goes
through a normal rapid charge before putting it into service.
