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 e lectric c ord having an equipment-grounding conductor and a grounding plug. Be sure the outlet is properly installed and grounded in accordan ce with all local codes and ord inan ces.
14. DANGER - Never alter the AC cord or plug. If it will not fit in th e outlet, 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 t he ada p te r illustrated in s ketches B and C, may be us ed to con nect
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 - Be fore 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 t op and bottom ven tilation. A minimum of 1/4" is required between the bottom of the charger and the surface on which it sits.

DESCRIPTION
The Universal Multi-unit Charger is designed to charge Ericsson personal 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
radios:
RADIO TYPE SLEEVE NUMBER
M-PA, M-PD, MTL, PLS, & TPX BML 161 51/001
PCS BML 161 51/00 2
M-RK BML 161 51/00 3
MONOGRAM BML 161 51/004
CAUTION
Recharging any battery pack or batteries other than the ones your
equipment was designed to charge may result in damage to equipm ent,
leakage, or explosion.

PRISM HP BML 161 51/005
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 v erify 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 directly to the wall due to the possible weight (26 lbs max) involved. We suggest mounting the charger on an 18" x 18" plywood panel secured to the
wall st uds. The fo llowing steps describe the proces s for installing the panel
and mounting the charger.
1. Locate the studs, s tuds are normally 16" apart, measured center-to-cen-
ter.
2. Posit ion the top of the panel at the desired height and drill pilot holes
through the panel into the s tuds. Secure the panel to the studs using four
2 1/2" long screws.
3. Using the templat e, 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 charge r w ill hold it firmly to
the wall.
9
Page 10
Solid walls - To install the charger on a brick or concrete wall, first in-
sert four wood dowels or fiber, plastic or masonry mounting anchors. Use
the following procedur e:
1. Using the mounting template provided, locate and mark the charger
keyhole mounting p oints. 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.
